LT11-13B Flashcard Review ESSC

Front

What is a convergent boundary?

Back

A tectonic plate boundary where two plates collide, often forming mountains or causing earthquakes.

Front

What geological feature is formed at a convergent boundary?

Back

Mountains, such as the Himalayas, are formed when two continental plates collide.

Front

What is a divergent boundary?

Back

A tectonic plate boundary where two plates move apart, often resulting in the formation of new crust.

Front

What is a transform boundary?

Back

A tectonic plate boundary where two plates slide past each other, causing earthquakes.

Front

What is the asthenosphere?

Back

The upper layer of the Earth's mantle, where convection currents occur.

Front

What is the primary component of continental crust?

Back

Granite.

Front

What is the primary component of oceanic crust?

Back

Basalt.

Front

At what depth is a pressure of 2.2 GPa likely found?

Back

At a depth of approximately 4,000 km.

Front

What causes convection currents in the Earth's mantle?

Back

The heat from the Earth's core causes the mantle material to heat up, become less dense, and rise, while cooler material sinks.

Front

What is the role of tectonic plates in earthquakes?

Back

The movement and interaction of tectonic plates can cause stress to build up, leading to earthquakes when released.
