The OLDEST seafloor is located?

Convection currents in the mantle cause plates to move.

The plates are floating on an ocean

How are ridges formed?

Two plates move away from one another.

Two plates collide with one another.

Two plates sink below Earth's surface.

Two plates slide beside each other.

Which of the following explains how mountains are formed?

Plates collide at convergent boundaries causing the crust to push upward.

Plates collide at divergent boundaries causing the crust to push upward.

Plates slide past each other at transform boundaries causing the crust to push upward.

Plates collide at convergent boundaries causing the mantle to push upward

Why does oceanic crust sub-duct under continental crust?

The oceanic crust is more dense.

The oceanic crust is less dense.

When the sea floor spreads apart, ridges are formed because....

as the plates pull apart, magma moves to the surface

sediments are deposited where the sea floor spreads

ocean water pushes down on the surrounding sea floor

underwater earthquakes lift the sea floor into long ridges

The THICKEST sea floor is located?

Farthest from the mid-ocean ridge

What is an earthquake?

A sudden movement of the Earth's crust caused by a release of stress accumulated along geological faults or by volcanic activity.

a. energy that builds up inside a volcanic mountain

a. energy being released when erosion occurs

a. molten rock pushing up through Earth's surface.

Mount St. Helens is located near the boundary of the North American plate (continental) and the Juan de Fuca plate (oceanic). Which statement describes the plate movement for the formation of this volcano

The Juan de Fuca plate moves under the North American plate.

The Juan de Fuca plate moves away from the North American plate.

The North American plate slides past the Juan de Fuca plate

The North AMerican plate moves under the Juan de Fuca plate

The Himalayas in Asia are an example of what type of plate boundary?

continent-to-continent convergent

What would you be most likely to find at a convergent boundary between a continental and oceanic plate?

Volcanic Mountains and trenches

If we were in a plane, Path B --> C is about the same distance as path E --> N. But, which path is the easier walk?

B --> C and E --> N are the same walking distance

What would be the most likely way this coastline would change over time?

The waves could erode the beach

A fire could destroy the vegetation

The beach would grow due to deposition

The beach will disappear due to plate tectonics

These images compare the same stretch of coastline. What is a possible reason for the change?

A major catastrophe such as a hurricane or tsunami destroyed the area

A fire destroyed the beach and surrounding area

Overtime, water eroded away much of the land

The beach and land went through a sever drought

A satellite image of an area in Florida shows a river with slight bends along its length. A second satellite image taken of the same area 10 years later shows the same river with a different course. What is the best explanation for the difference in the shape of the river's course between the two satellite images?

Water eroded the banks of the river and deposited the eroded soil on opposite banks, causing the river to form tighter bends

Wind blew waves across the water surface, eroding away the bank on one side of the river until the river's course changed its shape

Regular freezing and thawing of the river split the soil along the river banks, changing the shape of the river

Acid rain chemically weathered the banks along the river, forcing the river to wind back and forth
