A geologist examining a road cut at this location would recognize that layer i is.

Answers

The Principle of Lateral Continuity allows for the drawing of this conclusion.

"A geologist inspecting a road cut at this site would realize that Layer A is older than Layer B," the statement reads.

The lateral continuity principle, which stipulates that layers of sediment extend laterally in all directions, serves as the foundation for this finding.

As a result, the new layer B is nothing more than a continuation of the previous layer A.

The Lateral Continuity Law The Grand Canyon is a classic example of lateral continuity . On the two sides of the canyon, the same rock layers are readily visible. The corresponding rock layers are the same age since they were deposited at the same time

What is a continental plate and how does it matter to human existence?

Answers

Answer:

Earth has a moving, morphing which has lead to the evolution of life forms.

Explanation:

A continental plate or slab of rocks that form a landmass consists of lighter elements like silicon and aluminum and has a low density. It's formed by the heating and cooling of magmas over the surface is called the crust. The existence of life on earth would have not been possible if the continental plates were not formed, the earth is itself active and evolving this evolution led to the formation of the seven continent; landmasses and ocean basins as below them the earth is moving. Spreading of the lavas on ocean floor and the formation of rocks with different compositions and not only that plate tectonics have modulated the atmosphere also they are the driving creation of motion of tides and life-giving nutrients. Thus life emerged from the earth's ocean bottoms.

if a tectonic plate is moving at a rate of 1.25 inches a year, how many miles will it move in 100 million years

Answers

A tectonic plate can move 62.5 miles (approximately 100 km) in a million years at an average rate of 33 feet per 100 years (about 10 cm/year).

In a million years, how much do tectonic plates move?

The reason for this is that it existed millions of years before a tectonic movement split the two enormous continents apart. Land masses on Earth shift in relation to one another on average by 1.5 cm (0.6 inches) per year. The growth rate of a human toenail is approximately that.

How is the pace of tectonic plate movement determined?

The formula velocity = (distance traveled) / (travel time), or more simply, v = d / t, can be used to compute a rate of movement (velocity) if you are aware of both the distance and the duration of the "journey."

Igneous rocks (not including pyroclastic materials) formed from volcanism have a(n). ____________texture and have an origin.
O a) aphanitic; extrusive
Ob) phaneritic; intrusive
O c) aphanitic; intrusive
Od) phaneritic; extrusive

Answers

The correct answer is option c) aphanitic; intrusive.


Igneous rocks formed from volcanism can have either an aphanitic or phaneritic texture, depending on their cooling rate. Aphanitic texture refers to fine-grained rocks that cooled rapidly on or near the Earth's surface, while phaneritic texture refers to coarse-grained rocks that cooled slowly beneath the Earth's surface.In terms of origin, igneous rocks formed from volcanism are typically intrusive, meaning they solidify below the Earth's surface from magma. This is in contrast to extrusive rocks, which form from lava that solidifies above the Earth's surface.

a coarse rock composed of poorly cemented shells and shell fragments is called . group of answer choices travertine coquina shellstone dolostone

Answers

A coarse rock composed of poorly cemented shells and shell fragments is called coquina.

Coquina is a coarse sedimentary rock that is made up of loosely cemented shells and shell fragments. It is a biological rock, as its basic building components are shells of microscopic organisms that lived in the water.

Coquina is a type of limestone that is usually found in coastal areas. It is formed as a result of shell accumulation that occurred over time, where sea creatures' shells were deposited and later cemented. Coquina is a porous rock that is easy to cut and carve.

It was frequently used as a building material in the past because of its lightweight and ease of handling. It is made up of small pieces of broken cells. When they stick together they form coquina. Coquina is the only coarse rock which composed of poorly cemented cells and shell fragments.

Explain why Gandhi wanted to fight for the rights of the people of South Africa. What did he do while in South Africa?

Answers

Answer with Explanation:

Mohandas K. Gandhi/Mahatma Gandhi wanted to fight for the rights of people in South Africa because he, himself, experienced being racially segregated by being forcibly thrown off a train when he didn't follow the segregation rules.

He went to South Africa in 1893 to study law for one year and while being there, he realized how the Indians were being maltreated due to their race. This situation and his experience made him realize to fight for the injustices happening in the country and to stay longer in order to make a radical change. He founded the "Natal Indian Congress" in 1894 in order to fight for the Indian traders in South Africa and their struggle for independence. Later on, he organized a mass civil disobedience as a nonviolent protest.

A glaciovolcano is a volcano covered by glaciers. When it erupts, the glaciers covering it can melt. What is the most likely result of such an eruption?

Group of answer choices

a flood

an avalanche

a tsunami

an earthquake

Answers

Answer:

a flood

Explanation:

a flood – this is the right answer. As the eruption happens below the surface of the glaciers, the ice on the top melts under the erupting lava. This melted ice turns into the water, causing the flooding. These floods are called Jökulhlaups, meaning “glacial run” in the Icelandic language as it is in this country that glaciovolcano eruptions can often happen. This is the type of glacial outburst flood, and the most famous example is the eruption of Grímsvötn volcano in 1996.

an avalanche – this is not the right answer. There are glaciers and ice on the glaciovolcano, and it is snow that creates an avalanche. Also, the snow would be melted under the health.

a tsunami - this is not the right answer. The eruption of glaciovolcano can’t cause the tsunami.

an earthquake – this is not the right answer. Glaciovolcano eruption doesn’t cause an earthquake.

TRUE/FALSE. the region of norden is comprised of five sovereign states, each of which recognize a stronger cultural bond to their nordic neighbors than to any other cultural grouping.

Answers

The answer is FALSE. This is because the correct sentence is as follows:

The region of Norden is comprised of five sovereign states, each of which recognizes a stronger cultural bond with its Nordic neighbors than with any other cultural grouping.

How to apply the correct singular noun?

The subject "their" in "...to their Nordic neighbors..." is a plural, but we got the Region of Norden as a singular subject. So, we can change it with "its" and fill it in "...with its Nordic neighbors...".

A person, place, or thing is a singular noun. Having more than one thing or having more than one person or place refers to a plural noun. We simply add s to the end of the noun for a lot of cases to make it a plural form like phones, bears, rockets, etc.

Answers

The answer to the question is b. in their government - monarchies and written constitutions.

The Arabian Peninsula was under the influence of the Ottoman Empire for centuries until the British entered the region during World War I and helped establish new governments. Many countries in the Arabian Peninsula, such as Saudi Arabia, Kuwait, and Bahrain, have monarchies, which were established with British support. Additionally, the British helped in creating written constitutions for these countries, which provided a framework for the governments to operate. The British influence can also be seen in the architecture of some cities, where buildings were constructed in a style similar to those in Britain. Although the British influence can still be seen in some aspects of these countries, it is important to note that they have also retained their unique cultural identity.

1. The correct answer is (a) a restoration of degraded landscapes across the Earth. The context suggests that the restoration efforts are aimed at degraded landscapes globally, not limited to any specific region or country.

2. The correct answer is (b) Africa. The initial transformation of the landscape occurred in Africa, specifically on the Loess Plateau in China.

3. The correct answer is (a) soil ran down into rivers in runoff. Before the transformation, rainfall on the Loess Plateau caused soil erosion, leading to the soil running down into rivers as runoff.

4. The statement is (a) true. In Ethiopia, the government granted land to be set aside for natural vegetation to return, which helps slow down water infiltration into the ground.

5. The correct answer is (b) Loess Plateau, China. On the Loess Plateau, a clear running stream was created in just six years as a result of the restoration efforts and the implementation of various techniques to improve water retention and reduce soil erosion.

In conclusion, the restoration efforts discussed in the questions aim to restore degraded landscapes globally, with initial transformation occurring in Africa (specifically the Loess Plateau in China).
