6th (6.10D - Plate Tectonics/Geological Events) Part 2

Front

What is a rift valley?

Back

A rift valley is a lowland region that forms where tectonic plates move away from each other, causing the land to sink.

Front

What type of tectonic activity forms rift valleys?

Back

Rift valleys form where two tectonic plates move away from each other.

Front

What is a mid-ocean ridge?

Back

A mid-ocean ridge is an underwater mountain range formed by plate tectonics, where new oceanic crust is created as tectonic plates pull apart.

Front

What happens at a converging plate boundary?

Back

At a converging plate boundary, two tectonic plates move towards each other, often causing uplift, mountain formation, and earthquakes.

Front

What is the Pacific plate doing relative to the Nazca plate?

Back

The Pacific plate is moving to the west, and the Nazca plate is moving to the east.

Front

What geological feature indicates a converging plate boundary?

Back

Volcanoes can indicate a converging plate boundary, often forming an island arc.

Front

What is the result of two tectonic plates sliding past each other?

Back

When two tectonic plates slide past each other, it can cause earthquakes and create fault lines.

Front

What is uplift in geology?

Back

Uplift is the process by which Earth's crust is raised due to tectonic forces, often leading to the formation of mountains.

Front

What is the significance of a transform plate boundary?

Back

A transform plate boundary is where two plates slide horizontally past each other, which can lead to earthquakes.

Front

What is the role of magma in volcanic activity?

Back

Magma is molten rock beneath the Earth's surface that can rise to create volcanoes when pressure builds up.
