how is fossil evidence used to determine relative age of rocks?

Answers

Answer 1
Certain fossils, called index fossils, help geologists match rock layers. To be useful as an index fossil, a fossil must be widely distributed and represent a type of organism that existed for a brief time period. Index fossils are useful because they tell the relative ages of the rock layers in which they occur. I hope this helped!

What is the core of Jupiter thought to be composed of?
iron
helium
hydrogen
ice and rock

Answers

Answer:

The atmosphere of Jupiter is 90 percent hydrogen. The remaining 10 percent is almost completely made up of helium, though there are small traces of other gases inside.

Explanation:

Composed predominantly of hydrogen and helium, the massive Jupiter is much like a tiny star. But despite the fact that it is the largest planet in the solar system, the gas giant just doesn't have the mass needed to push it into stellar status.

The atmosphere of Jupiter is 90 percent hydrogen. The remaining 10 percent is almost completely made up of helium, though there are small traces of other gases inside.

These gases pile on top of one another, forming layers that extend downward. Because there is no solid ground, the surface of Jupiter is defined as the point where the atmospheric pressure is equal to that of Earth. At this point, the pull of gravity is almost two and a half times stronger than it is on our planet.

Are there times in which a person’s ethnicity could conflict with their nationality? Can you think of any examples?

Answers

Final answer:

A person's ethnicity may sometimes conflict with nationality. Ethnicity relates to cultural identity, while nationality is about legal statehood. Examples include Kurds across Middle Eastern borders and Jewish identity before the state of Israel, reflecting the complexities of ethnic and national identity coexistence.

Explanation:

Yes, there can be times when a person’s ethnicity conflicts with their nationality. Ethnicity relates to cultural factors such as nationality, culture, ancestry, language, and beliefs, while nationality is a legal relationship between an individual and a state. Ethnic conflicts can arise when people from the same ethnic group are divided by national borders or when a nation encompasses several ethnic groups with their distinct languages, cultures, or religious affiliations.

An example is the situation of Kurds who live across Turkey, Iraq, Iran, and Syria but do not have a separate state recognized as Kurdistan. Similarly, Jews before the establishment of Israel in 1948 lived across many nations without their own state, leading to the Zionist movement advocating for a Jewish homeland. In the United States, individuals can identify as African-American, Asian-American, or other hyphenated identities, showing a blend of ethnic and national identity. Forms and surveys often ask about race and ethnicity, providing categories that may not fully capture the diversity of people's backgrounds or how they self-identify, leading to potential conflict or uncertainty.

Moreover, ongoing social dynamics may influence whether feelings of ethnocentricity (favoring one's own ethnic group) or xenocentricity (preferring other cultures) are more prevalent at certain times, reflecting social forces or events. Additionally, as the categories used to define ethnicity are socially constructed, they can vary by time and location, further complicating the relationship between ethnicity and nationality. The example of Northern Ireland highlights a conflict where cultural forces, such as religion and language, have been used to drive political and social division. These examples underscore how ethnicity and nationality can sometimes be at odds, with real-world implications for individuals and societies.

The mercury entering the aquatic food chain and the plastic which absorbs it are both examples of which Planetary Boundary?

Answers

Answer:

Level of Chemical Pollution Boundary

Explanation:

The planetary boundaries represent sets of environmental parameters that are used to limit or caution the effect of humans activities on the environment. This is aimed towards protecting and preserving the environment for the future.

The planetary boundary was established in 2009 to curb the effects of the activities of humans in the environment. It represents the set of allowable limits to which the environment can take the effects of human actions on the environment. These planetary boundaries are group into nine parts according to the parameters they represent, namely, they are;

ocean acidification;depletion of the ozone layer;State of the nitrogen and phosphorus; global biogeochemical cycles; freshwater resources use; change in land use;the level of loss of biodiversity;level of particulate emission into the atmosphere and;the level of chemical pollution

The level of chemical pollution and toxic substance emission creates an indelible change in the planetary environment. Substances such as heavy metals pollutants, organic, and inorganic pollutants cause irreversible changes in the environment. Heavy metals such as mercury and lead entering water bodies pose an environmental threat to fishes likewise plastics.

These pollutants pose a chemical threat to the fishes and the level of chemical pollution planetary boundary.

Answers

Answer:

it is D

Explanation:

The Galápagos Islands are located at position one on the above map, and the Falkland Islands are situated at position five. As a result, choice (D) is the right response.

What is the location and significance of Falkland Islands?

On the Patagonian Shelf in the South Atlantic Ocean, there is an archipelago called the Falkland Islands. The Falklands are a British overseas territory with internal self-government, but the UK is in charge of its defense and foreign policy. Stanley in East Falkland is the major town and the capital.

The Falklands are made up of pieces of continental crust that were left over after Gondwana broke up and the South Atlantic opened up 130 million years ago. The islands lie about 300 miles east of Patagonia in southern Argentina in the South Atlantic Ocean on the Patagonian Shelf.

Given that the Falklands are the only military victory the UK has recorded without the aid of any allies, many people consider them as a symbol of national pride.

Hence, option (D) is accurate.

Climate plays an important role in agricultural yield. Examine the climate map of Africa above. In a short paragraph, explain the
correlation between Africa's climate and the problem of malnutrition throughout the continent.

Answers

Answer:

Well looking at the map you can tell that a vast majority of it is dry lands , this means that there is very limited space for agriculture. This can be harmful in many ways . A big reason is that they most likely do not grow enough crops in the green lands to have everyone be able to eat and have some all over Africa.

Explanation:

Final answer:

Africa's varied climate significantly affects agricultural yield, exacerbating malnutrition and food insecurity. The continent is experiencing unprecedented climate-related disruptions, including increased desertification and severe droughts, particularly in the Horn of Africa. Adapting agricultural practices to withstand extreme weather conditions is crucial for improving food security.

Explanation:

Climate has a significant impact on agricultural yield, which in turn affects malnutrition rates across Africa. The continent is experiencing climate disruption more acutely than other regions, with forecasted reductions of up to 50% in rainfed agricultural productivity in some countries by 2020, contributing to rising food insecurity and hunger. Varying climates across Africa, from the Mediterranean climate suitable for olives and citrus in the north to the arid Sahara and the savannas with lesser agricultural potential, exemplify the challenges for consistent food production. These issues are compounded by increased desertification, frequent floods and droughts, and water shortages, which could lead to more climate refugees and social-economic problems. As climate change continues, it leads to a cascade of problems such as poverty, hunger, and potential civil conflict. The World Food Programme links the climate crisis directly to a rise in global hunger, emphasizing Africa's vulnerability with increasing and unprecedented drought conditions in the Horn of Africa. Agricultural practices need to adapt to withstand the variable and extreme weather conditions, with measures such as increasing irrigation or advocating for the cultivation of drought-hardy crops.

Which phrases describe a Mercator projection? Select three options

2) sizes most features to scale
3) presents longitude lines as parallel
4) shows most accurately near the prime meridian
5) distorts land size as it moves away from the equator

Answers

Answer:

The correct answers are:

- is most commonly used;

Despite being a projection that is not the best representation, nor the most accurate one, still this map seems to be the most practical one for usage, so it is still the most popular one.

- presents longitude lines as parallel;

This projection is a cylindrical one, so all of the longitude lines are presented are lines that are parallel to one another.

- distorts land size as it moves away from the Equator;

The biggest problem with this projection is the distortion. The distortion becomes bigger and bigger with the increase in latitude, so it depicts the places around the poles as much larger than they actually are.

Explanation:

Answer:

(A.is most commonly used), (B.presents longitude lines as parallel) and (C.distorts land size as it moves away from the equator)
