Question

Explain how plate tectonics have changed Earth’s surface over time.

Answer 1

Answer:

When tectonic plates collide can form mountain ranges or large mountains, for example, the Himalayas is formed from the collision of two plates.

On the other hand when there is subduction (an oceanic plate sinks under the continental plate) mountainous systems are also formed, the lower plate melts and generates volcanic eruptions such as those that form some of the Andes mountains in South America.

Finally, deep depressions such as the Great Rift Valley are formed on land where plates are separated.
