Plate Motion Summative Assessment ODD - Oct.7

Front

What geologic process formed the Himalayan mountains?

Back

The Himalayan mountains were formed by the collision of tectonic plates, specifically the Indian Plate colliding with the Eurasian Plate.

Front

What is a Mid-Ocean Ridge?

Back

A Mid-Ocean Ridge is an underwater mountain range formed when two tectonic plates move apart, allowing magma to rise and create new oceanic crust.

Front

What is Earth's outer layer made of?

Back

Earth's outer layer, also known as the lithosphere, is made of hard, solid rock beneath both soil and ocean.

Front

Where can hard, solid rock be found on Earth?

Back

Hard, solid rock can be found under both continents and oceans, as it forms the outer layer of the Earth.

Front

What happens when tectonic plates move apart?

Back

When tectonic plates move apart, soft, solid rock from underneath can rise and harden, adding solid rock to the edges of the plates.

Front

What is a tectonic plate?

Back

A tectonic plate is a large, rigid piece of the Earth's lithosphere that moves and interacts with other plates, causing geological activity.

Front

What is the significance of plate boundaries?

Back

Plate boundaries are regions where two tectonic plates meet, and they are often sites of geological activity such as earthquakes and volcanic eruptions.

Front

What is the difference between oceanic and continental crust?

Back

Oceanic crust is thinner and denser than continental crust, which is thicker and less dense.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another and sinks into the mantle, often causing volcanic activity.

Front

What is a trench in geological terms?

Back

A trench is a deep, narrow depression in the ocean floor, formed by the subduction of one tectonic plate beneath another.
