Identify the type of plate boundary shown in this picture. Explain how this type of boundary provides evidence that Earth's magnetic poles have reversed.​

Answers

These are divergent boundaries! The magnetic poles being reversed can be proved but how the mountain range is now being pulled out. On convergent boundaries can create a mountain range by land colliding. Therefore, since the land is moving away from the center, it has created a divergent boundary on a set of mountains.

The type of plate boundary shown in the picture is the divergent plate boundary.

The divergent plate boundary refers to boundaries where plates continues to move apart from each other.

Activities that occurs around this boundary includes earthquakes and rise of molten magma from the mantle to Earth surface which solidifying to create new crust.

The divergent plate boundary is responsible for creation of new oceanic crust as plates move apart.

In conclusion, the type of plate boundary shown in the picture is the divergent plate boundary.

_____ Magma cools and hardens to form new crust.

_____ Magma is forced up towards the crust.

_____ The crust eventually falls into trenches and is recycled back to magma.

_____ Rock is pulled apart and magma fills the gap.

Answers

Answer:

1. Magma is forced up towards the crust.

2. Rock is pulled apart and magma fills the gap.

3. Magma cools and hardens to form a new crust.

4. The crust eventually falls into trenches and is recycled back to magma.

Explanation:

When there is a more than usual activity at a particular place in the mantle, it results in more pressure and magma to be pushed toward the surface. As this process goes on, gradually, the tectonic plate above it gets ripped apart as the magma progresses, breaks through, and pushes them away. The gap is constantly growing, so the magma continuous to come out constantly.

Because the magma, in this case, comes out on the seafloor, it hardens very quickly in the water, creating new rocks, thus new oceanic crust. As new crust is constantly formed, the one formed earlier is pushed to the sides and over the course of tens or hundreds of millions of years, it will come in a situation to be involved in a convergent plate boundary where it will subduct in a trench and will gradually melt and get recycled by the magma in the mantle.

Two factors which cause global climate change are listed below. Factor 1: Changes in the shape of Earth's orbit. Factor 2: Changes in the amount of Sun's heat received by the Earth's atmosphere and surface. Which of these statements is correct about the two factors which cause global climate change?

Answers

Hello. You forgot to show the answer options. The answer options are:

Factor 1 and Factor 2 are considered natural factors.

Factor 1 and Factor 2 are considered human induced factors.

Factor 1 is a human induced factor and Factor 2 is a natural factor.

Factor 1 is a natural factor and Factor 2 is a human induced factor.

Answer:

Factor 1 and Factor 2 are considered natural factors.

Explanation:

The changes that modify and influence the climate on our planet can be caused by humans, being called anthropogenic, or they can be natural, occurring in the nature of the planet without human intervention being made.

Changes in the shape of the earth's orbit and changes in the amount of sun heat received by the atmosphere are not man-made changes, but they occur naturally on the planet and have a strong impact on the global temperature changes to which we are subjected.

Please select the best answer from the choices provided
A
B
C
D



The answer is D.

Answers

The correct answer is D. The land has subsided about 30 feets in the last 100 years, and the rate is increasing.

Explanation

Mexico City is the capital of Mexico, a country in North America. This country during its pre-Hispanic stage was inhabited by civilizations such as the Mayas and the Aztecs who built great empires; the Aztecs built their main city Tenochtitlan on Lake Texcoco, later with the arrival of the Spanish this city was occupied by the colonizers who built houses and buildings in this area filling sectors of this immense lake. Over time, this lake seems to have been covered forming underground water sources such as aquifers, at the same time the city evolved and its infrastructure increased radically. Today this city is suffering from subsidence that has caused the buildings and the surface in general, to have sunk at least thirty feet during the last hundred years, because when Mexico City was built on Lake Texcoco, they were Aquifers and groundwater sources are used to supply water to the city, so they leave empty spaces in the sub-layers of the ground causing buildings and everything on the surface to sink. Additionally, during the last ten years, this pattern has increased making that the surface sink faster than before. According to the above, the correct answer is D. The land has subsided about 30 feet in the last 100 years, and the rate is increasing.
