index fossils existed for a ______ time period so they are ______ useful assigning ages to rocks that contain them. multiple choice question. long: not short; not long; very short; very

Answers

Answer 1

Index fossils existed for a long time period, so they are very useful in assigning ages to rocks that contain them.

Index fossils are commonly used in relative dating, a method of determining the age of rocks and fossils based on their relationship to other rock layers. Index fossils are species that lived for a relatively short period but had a wide geographic distribution.

These fossils can be found in multiple rock layers, allowing geologists to correlate and compare the ages of different rock formations.

The statement in the question suggests that index fossils existed for a long time period. This is because index fossils that lived for short periods, such as a few thousand to a few million years, would have limited utility in dating rocks.

By contrast, index fossils that span a longer time period, such as several million years or more, provide greater precision and confidence in assigning ages to rocks.

Therefore, index fossils that existed for a long time period are very useful in determining the relative ages of rocks that contain them.

Why is Jerusalem considered a “holy land” for all three of the religions (Judaism, Christianity, and Islam)? How has this land created conflicts for people in this region? Use at least two examples of any of the following to explain your answer: historical conflicts, present day conflicts, holy sites, border disputes etc.

Answers

Jerusalem is one of the oldest cities in the world. It has been conquered, razed and rebuilt. It is also revered in all three Abrahamic holy books. Many holy sites are  Al Aqsa Mosque, the Dome of the Rock and the Western Wall.

It has not always been an easy journey. Pope Urban II launched the Crusades in 1095. What followed was a series a bloody battles over the fate of Jerusalem. The Christian armies retook the city initially but were later routed by famed Muslim leader, Saladin. The Crusades ended 200 years later with Muslims in control of the Holy Land. But Christians learnt much from the skilled Arab world in warfare and science.

Jerusalem, though, is more than just an historic place for Christians: it is also a metaphor for all that they yearn for in this world and the next. It is a perfect place, a golden city, a paradise they will one day attain after death. It also represents creation of a new earth.

Islamic rule over Jerusalem lasted for 12 centuries, longer than any other rule, whether Israelite, Roman, Persian or Christian. Political highlights included Caliph Omar’s conquest, Saladin’s reconquest from the crusaders, and Suleyman the Magnificent’s rebuilding of the city walls. In addition, Jerusalem has a strong Islamic intellectual and spiritual history – for example, the theologian Al-Ghazali is said to have spent an entire year in retreat, meditation and prayer in one of the minarets of the “Noble Sanctuary.”

Judaism, meanwhile, began more than 3,500 years ago. Jews believe that God anointed them as the chosen people to set an example of holiness. There are about 15 million Jews worldwide

According to Jewish tradition, Jerusalem is Mount Moriah, the location of the binding of Isaac. The Hebrew Bible mentions the name "Jerusalem" 669 times, often because many mitzvot can only be performed within its environs. The name "Zion", which usually refers to Jerusalem, but sometimes the Land of Israel, appears in the Hebrew Bible 154 times.

Hey there! I'm happy to help!

The topography of the Earth is all of the unique changes in landscape with the different formations, elevation changes, etc.

It appears that this question is talking about rivers because it mentions something that carries huge amounts of water. Rivers are a principal factor in the sculpting of the Earth's surface as water can erode rocks and transport the sediments to other locations.

Rivers take water and transport to the sea. The sea is basically the ending point of the rivers as there is no where else for it to go. It is at the lowest elevation, so the rivers can't really flow anywhere else now.

How many different sandwiches are possible? Explain your reasoning.

Answers

If a submarine sandwich shop makes sandwiches with one kind of bread, one protein, one choice of cheese, and one vegetable. The number of different sandwiches that  are possible is: 120.

What is the possible combination?

Let's assume there are:

b=  bread

p= protein

c= cheese

v= vegetables

So,

Total number of sandwiches = b *p * c * v

For instance there would be a total of 11 distinct sandwiches if there were 3 bread options, 4 protein options, 2 cheese options, and 5 vegetable alternatives.

Total number of sandwiches = 3 * 4 * 2 * 5

Total number of sandwiches  = 120

With the specified options for bread, protein, cheese, and veggies, there would be 120 distinct sandwiches that might be made in this scenario.

New oceanic crust is ultramafic in composition. d. Some magma generated during seafloor spreading spills out to produce a new layer of seafloor called gabbro.

Answers

Answer:

d. Some magma generated during seafloor spreading spills out to produce a new layer of seafloor called gabbro.

Explanation:

The magma is spilled from the mid-oceanic ridges and spreads onto the seafloor creating a newer seafloor. This is why it's called as the divergent boundary due to the spreading of magma on both sides of the floor. Grabbo is a coarse-grained mafic intrusive igneous rock and is formed at the oceanic ridges.

Did Mars undergo the same processes that occurred on Earth?

Answers

Mars has undergone many of the same geological processes as Earth, but the specific details of these processes have been shaped by the planet's unique characteristics and history.

Mars and Earth share many similarities, including their rocky composition and their location in the inner solar system. However, there are also significant differences between the two planets.

While both planets formed from the same solar nebula and underwent differentiation into a metallic core and a rocky mantle, Mars is smaller than Earth and cooled faster.

As a result, Mars lost its internal heat more quickly and its tectonic activity ceased much earlier than on Earth. Mars also has a much thinner atmosphere than Earth, which affects the planet's geology and weather patterns.

C. Describe the spatial pattern of orange cultivation in Florida. FRQ

Answers

Answer:

Explanation:

The spatial pattern of orange cultivation in Florida is characterized by a concentration of citrus groves in the southern part of the state, particularly in the central and southern regions. The counties of Polk, Hendry, and Highlands are some of the top producers of oranges in the state, with other major citrus-growing regions located in the counties of Hardee, DeSoto, and Indian River.

The concentration of orange groves in this region is due to a number of factors, including favorable climate and soil conditions, availability of irrigation water, and access to transportation infrastructure for shipping citrus products to market. The subtropical climate of southern Florida provides a long growing season and ample sunshine, which is ideal for citrus production. In addition, the sandy soils in these regions provide good drainage and are rich in nutrients that are essential for citrus growth.

Florida's orange groves are typically arranged in a grid-like pattern, with individual trees spaced at regular intervals within rows. The size and shape of groves can vary widely depending on factors such as soil conditions, topography, and land availability. Some groves are small and irregularly shaped, while others can cover hundreds of acres and stretch for miles.

Overall, the spatial pattern of orange cultivation in Florida is influenced by a range of factors that interact to create a unique agricultural landscape. While there are some regional variations in the distribution of citrus groves, the concentration of orange production in the southern part of the state is a defining characteristic of Florida's citrus industry.

From the early Mesoamerican civilizations to the diverse populations that live there today, Mexico’s citizens have remained proud of their heritage and their country.

Many rural communities maintain strong allegiances to regions, often referred to as patrias chicas (small homelands). The large number of indigenous languages and customs in these regions, especially in the south, naturally accentuate cultural differences. However, the indigenismo (ancestral pride) movement of the 1930s played a major role in unifying the country and solidifying national pride among the various populations".

Catholicism has become the dominant Mexican religion since first being introduced during Spanish colonization in the 16th century. Currently, more than 75 percent of Mexico’s population is Catholic, making Mexico the second-largest Catholic country in the world after Brazil. During the Mexican Revolution of 1917 and the administration of President Plutarco Elías Calles (1924 – 1928), there was a strong anti-clerical movement.

Answers

Toronto, Canada on a typical winter day is most likely to have the highest dew point.

The dew point is a measure of the moisture content in the air and represents the temperature at which the air becomes saturated, leading to condensation and the formation of dew. In general, warmer air can hold more moisture than colder air, so environments with higher temperatures tend to have higher dew points. Among the given options, Toronto, Canada on a typical winter day is most likely to have the highest dew point. During winter in Toronto, temperatures are generally colder compared to the other locations. While it may seem counterintuitive, colder air in winter can still hold a significant amount of moisture, especially if there are sources of moisture like nearby bodies of water or if the air has originated from a region with higher humidity. This combination of colder temperatures and adequate moisture can lead to a relatively high dew point in Toronto during a typical winter day.

On the other hand, San Diego on a typical day, San Diego during a Santa Ana, and Atlanta, Georgia on a typical summer day are likely to have lower dew points compared to Toronto on a typical winter day. San Diego has a Mediterranean climate characterized by mild temperatures and low humidity. The Santa Ana winds, which are dry and warm winds blowing from the desert regions, exacerbate dry conditions and decrease the dew point in San Diego. Similarly, Atlanta, Georgia experiences a humid subtropical climate, but on a typical summer day, the dew point may still be lower compared to Toronto's winter conditions due to the relatively higher temperatures in Atlanta's summers.

Neptune is too faint to be seen with the human eye due to its immense distance from the Sun, hence the discovery was made using a telescope. A moon orbiting Neptune was quickly found by astronomers, but it took more than a century to find a second one.
