How does the climate affect the South region of the U.S?

Which statements describe Wegener’s ideas that became known as the theory of continental drift? Check all that apply.

yarga [219]

Answer:

Options (1), (2) and (3)

Explanation:

Alfred Wegener was the person who first invented the continental drift theory. He observed that the continents move from one place to another with respect to a fixed point. He put forward many pieces of evidence but he was unable to explain the main mechanism that is responsible for these motion of continents.

The pieces of evidence that were given by Alfred Wegener supporting the continental drift theory are-

(a) The continents move slowly and continuously from one place to another and the edges of these continents perfectly match with the other.

(b) Similar fossil assemblages were found in currently separated continents.

(c) Similar rock types are also found and suggested that the continents were once all together forming a huge landmass which is known as the Pangaea.

Later this theory was modified into a more simple and universally accepted theory which is commonly known as the Plate tectonic theory.

Hence, the correct answers are options (1), (2) and (3).

Otoliths are small stones in the semicircular canals that shift when the head moves. Please select the best answer from the choi

viva [34]

This question actually refers to body parts: otoliths are small structures in your inner ears (in the semicircular canals, so this part is correct) that shift when you move - to help you sense your body position (so this part is also true).

But they're not exactly stones - they are small particles, so that's why the statement is false.

A plate moving at a rate of 4 is moving toward a plate that is 10,000 km away. In how many years will the plates collide?

disa [49]

Answer:

The plates will collide in 250 million years.

Explanation:

Earth is divided into numerous plates. All of them are in constant motion which is driven by the convection currents in the mantle. All plates move in different directions, with some moving toward each other, some moving away from each other, and some slide past each other.

In this case, we have a plate that moves toward another plate, and the other plate presumably is static (not really possible, but still). The plate that moves is moving with 4 cm per year, and the distance between the plates is 10,000 km, so in order to get a result in how many years they will collide, we need to convert the km into cm and then simply divide them by the speed of the plate.

1 m = 100 cm

1 km = 1,000 m

1,000 x 100 = 100,000 cm

100,000 x 10,000 = 1,000,000,000 cm

1,000,000,000 / 4 = 250,000,000

We get a result of 250 million, meaning that the plates will collide in 250 million years.

Based on the map, which of the following can be identified as a true statement about Northern Ireland?

Licemer1 [7]

Answer: d. It is physically separate from the rest of the United Kingdom, a multinational state.

Explanation:

Northern Island is one of the constituent countries of the United Kingdom and from the map one can see that it is physically separated from the rest of the U.K. .

The entire island where the Irish countries are situated used to be part of the U.K. up until 1922 when the current Republic of Ireland seceded from the U.K. after the Irish War of Independence.
