Earth's Layers and Tectonic Activity

Front

The Earth has 4 main layers.

Back

Crust, mantle, outer core, inner core

Front

Convergent Boundaries

Back

Plates move toward each other, creating volcanoes and mountains.

Front

Transform Boundaries

Back

Plates slide past each other, causing earthquakes and cracks.

Front

Lava

Back

Front

Most volcanoes are located at which boundaries?

Back

Divergent and convergent tectonic plate boundaries.

Front

Natural Hazards

Back

Extreme events that can have devastating effects.

Front

Subduction

Back

When one tectonic plate moves under another.

Front

Natural hazards can be caused by tectonic or climatic conditions.

Back

Tectonic hazards are caused by tectonic plates moving, while climatic hazards are caused by certain weather conditions.

Front

Weathering breaks down pieces of the Geosphere.

Back

Weathering breaks down rocks and soil, which are then moved through erosion.

Front

Chemical weathering changes the minerals in rocks.

Back
