Plate Tectonics ES.7 b/c

Front

What is Plate Tectonics?

Back

The theory that explains the structure and movement of the Earth's lithosphere, which is divided into tectonic plates that float on the semi-fluid asthenosphere.

Front

What are the three main types of plate boundaries?

Back

Divergent, Convergent, and Transform boundaries.

Front

What occurs at divergent boundaries?

Back

Tectonic plates move away from each other, leading to the formation of new crust, such as rift valleys and mid-ocean ridges.

Front

What is a convergent boundary?

Back

A tectonic plate boundary where two plates collide, often leading to subduction or mountain formation.

Front

Define subduction zone.

Back

An area where one tectonic plate is being forced under another, often resulting in volcanic activity.

Front

What is the epicenter of an earthquake?

Back

The point on the Earth's surface directly above the hypocenter (focus) where the earthquake originates.

Front

What is a rift valley?

Back

A lowland region formed by the divergence of tectonic plates, characterized by steep walls and a central block.

Front

What are volcanoes and how do they form?

Back

Volcanoes are openings in the Earth's crust that allow molten rock, ash, and gases to escape, often forming over hot spots or at divergent boundaries.

Front

What is karst topography?

Back

A landscape formed from the dissolution of soluble rocks, characterized by features like sinkholes and caves, commonly found in the Valley and Ridge province.

Front

What is the difference between the epicenter and the hypocenter of an earthquake?

Back

The epicenter is the point on the surface directly above the hypocenter, which is the actual location within the Earth where the earthquake originates.
