Drumlins are elongate hills of glacial till that are molded by glaciers that flow over them. They are typically teardrop-shaped with a steep slope facing the direction from which the glacier came and a more gradual slope on the other side.

Drumlins are elongated hills made of glacial till, which are formed as glaciers move over them. The shape of a drumlin is usually asymmetrical, with a steeper side facing the direction the glacier came from and a more gently sloping side on the opposite side. This distinct shape is due to the way the glacier molds the till as it moves over the hill.

Kettle holes, and eskers are not correct in this context as they refer to different glacial features: Loess: Wind-blown silt deposits that can accumulate over large areas, not specifically related to glaciers. Kettle holes: Depressions formed by melting ice blocks that were buried in glacial till. Eskers: Sinuous ridges composed of gravel and sand that were deposited by meltwater streams flowing beneath a glacier.

Elongate hills of glacial till that are molded by glaciers that flow over them are called drumlins.

These landforms are usually oval or elongated in shape and can range from a few meters to several kilometers in length. Drumlins are typically formed from the debris and sediment that glaciers carry along with them, which gets deposited in layers and compressed over time. These landforms are often found in clusters or "swarms" and can give clues about the direction and speed of glacier movement. In contrast, loess refers to a type of wind-blown sediment, kettle holes are depressions left behind by melting ice blocks, and eskers are long ridges of sand and gravel deposited by streams that flowed under glaciers.

Explanation:

The 200 years of accumulated strain were released during that earthquake.

To estimate the number of years of accumulated strain released during the Fort Tejon earthquake, we need to use the average rate of fault movement calculated in problem 1b. Let's assume that the average rate of fault movement is 5 cm/year.

To calculate the number of years of accumulated strain, we can use the formula:

Accumulated strain = Offset / Average rate of fault movement

In this case, the offset is 10.0 meters (33 feet) and the average rate of fault movement is 5 cm/year, which is equal to 0.05 meters/year.

Plugging these values into the formula, we get:

Accumulated strain = 10.0 meters / 0.05 meters/year = 200 years

This means that the accumulated strain in the region was released during the Fort Tejon earthquake, which suggests that there were no major earthquakes in this region for at least 200 years prior to 1857. However, this is a very simplistic assumption, and the actual number of years of accumulated strain could be much higher or lower depending on various factors such as the geometry of the fault, the strength of the rocks, and the rate of stress accumulation.

Explanation:

In summary, a fault is a fracture or crack in the Earth's crust where movement and displacement of rock masses occur. They are primarily formed at plate boundaries and play a crucial role in shaping the Earth's surface and triggering earthquakes.

A fault is a geological feature where the crust of the lithosphere has fractured or cracked due to tectonic forces. It is a zone of weakness in the Earth's crust that allows for movement and displacement of rock masses. Faults can occur in various locations and have different orientations and characteristics.

Faults are primarily formed at plate boundaries, where tectonic forces exert pressure on the Earth's crust. The movement along faults can be either horizontal (strike-slip faults), vertical (normal faults), or a combination of both (oblique faults). When tectonic forces exceed the strength of the rock, it causes the rock to fracture and slide along the fault plane.

Faults play a significant role in shaping the Earth's surface. They can create mountains, valleys, and rift zones. The movement along faults can cause earthquakes, as the stored energy in the rocks is suddenly released. Earthquakes occur when the stress along the fault overcomes the friction holding the rocks together, resulting in rapid movement and shaking.

Faults are crucial in understanding the dynamics of tectonic plates and the geological history of an area. By studying the orientation, displacement, and rock formations associated with faults, geologists can gain insights into the past movements of the Earth's crust and reconstruct the geological events that shaped the landscape.

As the glacier passes over the marked rock in the long-term study, the rock may experience several different effects. Firstly, the weight and pressure of the glacier may cause the rock to become compressed and flattened.

Additionally, the movement of the glacier may cause the rock to shift or move from its original location. Over time, the constant movement and pressure of the glacier may cause the rock to become eroded or broken down into smaller pieces. Finally, as the glacier retreats and melts, the rock may be left behind in a new location or may be exposed to new environmental conditions that could further affect its appearance or composition.

Population distribution is primarily influenced by physical features and environmental conditions.

Explanation:

iThe areas in which people have been settling historically, but nowadays as well, have always been the areas that offer the best conditions. Basically, the more suitable the physical features and environmental conditions, the more people will move in and live in the area, and vice versa. This can be noticed very easily if we see where the population is most concentrated and where it is very sparse.

The areas that are dominated by lowlands through which there is river/s passing by, with temperate or mediterranean climate, tend to be the best for the people to live in. This can simply be attributed to the abundance of water, fertile soil, and pleasant climate. On the other hand, the areas dominated by steep mountains, deserts, tropical rainforests, taiga, and tundra have always been avoided because of the extremes in the climate and poor living conditions.

lnternal structure of earth

The size of the earth about 12,750 km in diameter was known by the ancient Greek but it was not until the turn of the 20th century that scientists determined that our planet is made up 3 main layers crust , mantle and core.

External structure of earth

According to the classification according to chemical composition , the Earth is divided into crust , mantle and core in physical behavior it is divided into lithosphere, mesosphere , outer core and inner core.

The earliest needles were made of bone or wood. Modern needles are manufactured from high carbon steel wire and are nickel or 18K gold plated for corrosion resistance.

Oceanic crust differs from continental crust in a number of ways, including thickness, density, age, and chemical make-up. Like continental crust, however, oceanic crust is destroyed in subduction zones.

The lavas are generally of two types: pillow lavas and sheet flows. Pillow lava appears to be fashioned just as the name suggests—like big, overstuffed pillows with a cross section measuring 1 m (3 ft) and up to several m in length.

At the spreading hubs, they frequently grow into little hills that are tens of metres high. The appearance of sheet flows is that of wrinkled bed sheets. They typically cover a larger area than pillow lavas and are thinner than those lavas (only about 10 cm [4 inches] thick).

Answer:

The lithosphere-asthenosphere boundary

Explanation:

because is conventionally taken at the 1300 °C isotherm. Below this temperature (closer to the surface) the mantle behaves rigidly; above this temperature (deeper below the surface) it acts in a ductile fashion.

Within Earth's mantle, convection cells move lithospheric plates toward subduction zones and away from mid-ocean ridges.

Convection cells in the mantle play a crucial role in driving the movement of tectonic plates on the Earth's surface. These cells are generated by the transfer of heat from the deeper parts of the mantle towards the surface. As hot material rises and reaches the top of the mantle, it spreads horizontally and moves the overlying lithospheric plates.

At subduction zones, where one tectonic plate is forced beneath another, the convection cells cause the lithospheric plates to move towards these areas of subduction. Here, one plate descends into the mantle, creating a convergent boundary where intense geological activity occurs, such as the formation of volcanic arcs and mountain ranges.

On the other hand, at mid-ocean ridges, where tectonic plates diverge, the convection cells drive the lithospheric plates away from these spreading centers. As new material rises from the mantle, it pushes the plates apart, creating seafloor spreading and the formation of new oceanic crust.

In summary, convection cells in the mantle move lithospheric plates toward subduction zones and away from mid-ocean ridges, driving the dynamic processes of plate tectonics.

The greenhouse effect is a natural process that keeps the Earth's atmosphere warm enough to support life. It occurs when gases in the atmosphere trap heat from the sun, which warms the Earth's surface. There are several features that contribute to the greenhouse effect on Earth.

The first feature is infrared radiation that is reradiated back to the ground. This occurs when heat energy from the sun enters the Earth's atmosphere and warms the surface. The surface then releases some of this heat energy back into the atmosphere in the form of infrared radiation. This radiation is then trapped by greenhouse gases in the atmosphere, which keep the heat close to the Earth's surface.
The second feature is infrared radiation that is radiated from the ground into the atmosphere. This occurs when heat energy from the Earth's surface is released into the atmosphere in the form of infrared radiation. This radiation is then trapped by greenhouse gases, which keep the heat close to the Earth's surface.
The third feature is radiation from the sun heating the ground. This occurs when the sun's rays heat the Earth's surface, which then releases heat energy back into the atmosphere in the form of infrared radiation.
Finally, there is infrared radiation escaping into space. This occurs when heat energy from the Earth's surface is released into the atmosphere and escapes into space in the form of infrared radiation. This radiation is not trapped by greenhouse gases and therefore does not contribute to the greenhouse effect.
Overall, the greenhouse effect is a complex process that involves several features, including infrared radiation from the sun and the Earth's surface, greenhouse gases in the atmosphere, and the escape of heat energy into space.

The length of daylight during the equinox varies depending on location. At the equator, the length of daylight is equal, while at the poles, it can vary greatly.

The equinox occurs twice a year, once in March and again in September. During the equinox, the length of daylight and darkness are equal all over the world. At the equator, the length of daylight during the equinox is approximately 12 hours, and the length of darkness is also approximately 12 hours. This is because the equator receives direct sunlight during the equinox, causing equal amounts of daylight and darkness.
However, at the poles, the length of daylight during the equinox is very different. The North Pole experiences 24 hours of daylight during the equinox, while the South Pole experiences 24 hours of darkness. This is because of the tilt of the Earth's axis. The North Pole is tilted towards the sun during the equinox, while the South Pole is tilted away from the sun.
