Explanation:

The atmosphere is composed of five distinct layers. They are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The temperature varies significantly in each layer, and each layer contains different elements.

Troposphere:

This is the lowest layer of the atmosphere, where all weather occurs. The air gets cooler as you climb higher in the troposphere, as it does in all other layers of the atmosphere.

Stratosphere:

The stratosphere extends from the troposphere's top to about 50 kilometers above Earth's surface. This layer is distinguished by the presence of the ozone layer, which absorbs a significant portion of the sun's harmful ultraviolet (UV) radiation.

The temperature of the stratosphere grows with increasing height, reaching a maximum of around 0°C (32°F) at the layer's top.

Mesosphere:

This is the layer that lies just above the stratosphere. The mesosphere is the location where many meteoroids burn up as they enter Earth's atmosphere. The temperature of this layer decreases with increasing height, reaching a low of -90°C (-130°F) at its top.

Thermosphere:

The thermosphere is the fourth layer of the atmosphere. It begins around 80 kilometers above Earth's surface and stretches to the exosphere. This layer is where you'll find the Aurora Borealis, or Northern Lights. The temperature of the thermosphere is highly variable. During the day, the air can reach 1,500°C (2,732°F), but at night, it can dip as low as -120°C (-184°F).

Exosphere:

The outermost layer of the Earth's atmosphere is known as the exosphere. The temperature in the exosphere varies depending on the activity of the sun.

This layer extends from the top of the thermosphere, approximately 500 kilometers above Earth's surface, to approximately 10,000 kilometers.

Censuses are preferable over capture-mark-recapture in small populations, when habitat quality changes significantly, or for specific life stages, ensuring more accurate population estimates.

Ecologists might prefer an actual count of every individual in a population (census) rather than using the capture-mark-recapture method in the following situations: Small population sizes: When the population is small, ecologists might choose to use a census rather than the capture-mark-recapture method because of the small sample size. If the sample size is too small, then the precision of the estimates becomes weak.

In such instances, the probability of animals being recaptured may be too small, causing imprecise estimates. Changes in habitat quality: A capture-mark-recapture method is an excellent tool for comparing population estimates between different years, but it cannot capture any changes in the habitat. The population estimate becomes questionable if the habitat has undergone significant changes between the capture periods.

For example, a census would be the most effective method for detecting a change in the population of a migratory bird species caused by habitat loss or disturbance, while the capture-mark-recapture method would be unsuitable. Example: Say that a particular bird species population is being monitored over time with the capture-mark-recapture method.

The population of the birds increased due to an increase in the food supply, but during the same period, a group of trees that provided shelter for these birds were destroyed by a forest fire. The bird population size estimate obtained through the capture-mark-recapture method would not account for the destruction of the trees and therefore would be invalid.

Specific life stages: When dealing with particular life stages or sizes of the population, a census may be necessary. For example, during the breeding season, migratory birds form colonies, which makes it hard to capture them using the capture-mark-recapture method. In such situations, it may be more effective to do a census.

The following sentence "Scientists use sound waves to study the ocean floor." is true. The option "a" is true about mid-ocean ridges Mid-ocean ridges are mountain ranges on the ocean floor.

The process that slowly adds new rock to the ocean floors is called sea-floor spreading.

The option "a" and "b" are true about sea-floor spreading: Harry Hess came up with the idea of sea-floor spreading, and sea-floor spreading happens at mid-ocean ridges.

Sound waves are longitudinal waves that are transmitted through any solid, liquid, or gas medium. They need a substance for transmission because their particles vibrate to produce waves that propagate through the substance.

The transmission of sound waves is due to the interaction between the molecules of the medium and the particles of the sound wave.

The sedimentary and metamorphic rocks that make up the continental crust are two different types of rocks.

Metamorphic rocks are created by heat and pressure, while sedimentary rocks are created by pressure and compaction. Sedimentary rocks, together with metamorphic rocks, are what make up the earth's crust because they are mostly located below the crust. Sedimentary rocks are created by the lithification of pre-existing rock or the fragments, bones, and shells of extinct organisms. Rocks are eroded and weathered into minute fragments, which are subsequently transported and deposited alongside other fragments of rock, or sediments. When rocks are crushed or subjected to intense pressure, such as thousands of feet of bedrock, they typically transform into metamorphic rocks.

New oceanic crust and lithosphere are formed at divergent boundaries. Divergent boundaries are areas where tectonic plates move away from each other, causing magma to rise up and solidify, creating new oceanic crust and lithosphere. Option  C .

This process is known as seafloor spreading and is driven by mantle convection. As the magma solidifies, it forms a new oceanic plate that moves away from the divergent boundary, allowing for the formation of new oceanic crust and lithosphere. Divergent boundaries can be found in places such as the Mid-Atlantic Ridge and the East Pacific Rise, where new oceanic crust and lithosphere are constantly being formed.

There are two ways to more accurately measure the distance to an object using parallax. First, you could increase the baseline, which is the distance between the observer's two viewpoints. This would result in a larger parallax angle, making it easier to accurately measure the distance. Second, you could improve the precision of the measurement by using more advanced technology, such as telescopes or specialized cameras, to capture more detailed images and measurements of the parallax angle. Both of these methods can help to improve the accuracy of measuring distance using parallax.

Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight and is measured by the angle or half-angle of inclination between those two lines. Due to foreshortening, nearby objects show a larger parallax than farther objects, so parallax can be used to determine distances.

To more accurately measure the distance to an object using parallax, you can:
1. Increase the baseline: By increasing the distance between the two observation points, you can create a larger parallax angle, which will result in a more accurate measurement of the object's distance.
2. Improve angular measurements: Using more precise instruments or techniques to measure the parallax angle will help to reduce errors and increase the accuracy of the distance calculation.

Parallax angle is an angle that describes the apparent shift in the position of an object when it is viewed from two different points. The angle is formed by two lines drawn from the two observation points to the object, and the angle is measured at the object. Parallax angle is commonly used in astronomy to determine the distance to nearby stars. By observing the star from two different points in the Earth's orbit, astronomers can measure the parallax angle and use trigonometry to calculate the distance to the star. The greater the parallax angle, the closer the star is to the Earth. Parallax angle is also used in surveying and navigation to determine distances and positions.

The value representing the expansion of the universe is 7402.

The speed of a galaxy is dependent on its distance.

Formula used:

Speed = Distance / Time ⇒ Time = Distance / Speed

We know,1 Mpe = 1,000,000 PC1 pc = 3.0857 × 10¹³ km

Converting 1 Mpe into km, 1 Mpe = 1,000,000 pc × 3.0857 × 10¹³ km/pc= 3.0857 × 10¹⁹ km

Converting the given value to km/s: 7402 km/Mpc × 1 Mpc/3.0857 × 10¹⁹ km= 2.3975 × 10⁻¹⁰ km/s

We know that, Speed = Distance / Time  

Speed = 2.3975 × 10⁻¹⁰ km/s

Using the distance of one light-year as the distance, i.e., 9.461 × 10¹² km,

Time = Distance / Speed= 9.461 × 10¹² km/ 2.3975 × 10⁻¹⁰ km/s= 3.946 × 10²¹ s

The wind belt that causes the easterly movement of the mid-latitude cyclone is the westerlies.

The westerlies, also known as anti-trades or prevailing westerlies, are the dominant winds in the middle latitudes between 30 and 60 degrees latitude that blow from the west toward the east. They originate from the high-pressure regions in the horse latitudes, move in a poleward direction, and generally control extratropical cyclones in this way.

At midlatitudes, the dominant winds are westerlies, which originate in the west. They are nourished by winds from the high-pressure horse latitudes and polar easterlies, which are sandwiched on either side of them.
