THIS IS THE BEST ANSWER 👇

Explanation:

1.The slowly increasing distance between South America and Africa is due to the spread of the seabed.

In 1960, Harold Hammond Hess of Princeton University and Robert Dietz of the U.S. Naval Electronics Laboratory introduced the idea of ​​moving the seabed and transporting the continents with it. This phenomenon is called plate tectonics. Where it occurs, plates move apart at the ridges of the mid-ocean and create a new seabed during the spread of the seabed.

2.Old Faithful Geyser in Yellowstone National Park in the United States gets its energy from Hotspot.

Researchers have discovered that there is a large underground hotspot .i

giving energy to all the famous Yellowstone geysers. Beneath the yellow stone, hot molten rock is flowing causing the pressure.

3. Layered erosion-exposed sedimentary rock can be seen while looking at the Grand Canyon in the United States.

Grand Canyon consists of horizontal layered rocks and lava flows. There are about 40 major sedimentary layers in a Grand canyon ranging in age from 200 million to 2 billion years old.

4. Australia is composed of a relatively old and thick continental crust.

The continental crust of Australia, excluding thinning margins, has an average thickness of 38 km, with a thickness range from 24 km to 59 km.

5. The Marianas deep sea trench is the result of abduction.

Depression is the oceanic trench in the sea floor, which is narrow in width but very long. Marianas trench is the crescent-shaped trench and is known for the deepest points in the world. Kidnapping is the result of two plates coming together and one thrust under the other.

6. Seabed in the Atlantic Ocean between North America and Europe is composed of dense, relatively young rock.

The outermost layer of land lithosphere is the seabed crust or oceanic crust found in the areas near the mid – sea ridges or the spread of the sea floor.

7. Earthquakes that occur in Southern California are usually above fault.

These earthquakes are due to the movement of huge blocks of earth’s crust.
