Science Ch 14: Earth's Changing Surface

The squeezing force at a convergent boundary

The hypothesis that continents move developed by Alfred Wegner

Where two plates move towards each other

Where two plates move apart from each other

States that Earth’s crust is broken into rigid plates that move over Earth’s surface slowly

The side-by-side dragging force at transform boundaries

The area where one plate slides under another

The pulling force at a divergent boundary

Where two plates slide horizontally past each other

A large depression in the center of a volcano

The rupture and sudden movement of rock along a break or crack in Earth’s crust

The surface along which the crust moves

Locations where volcanoes form far from plate boundaries

Long stream of molten rock

The mountains that form as this lava builds up and cools

Small pieces of solidified lava in the atmosphere

The process of changing the composition of rocks and minerals by exposure to water and the atmosphere

The makeup of something

The process of laying down eroded material in a new location

The moving of weathered material, or sediment, from one location to another

The process of breaking rock into small pieces without changing the composition of the rock

The minerals and small pieces of rock

Consists of weathered rock, mineral material, water, air, and organic matter from the remains of organisms

The process that breaks down rocks, changing Earth’s surface over time
