Old oceanic crust is more dense than new oceanic crust because it is

According to Wegener’s hypothesis of continental drift,

1

A place where two plates slip past each other, moving in opposite directions, is known as a

1

In which location would you most likely find volcanoes?

1

Particles of hot soup rise slowly in a pot simmering on a stove. As the hot soup nears the surface, it begins to cool. The cooler soup sinks, forming a constant movement of soup that moves energy toward the surface of the pot. This constant movement of the soup in the pot is called a(n)

A collision between two pieces of continental crust at a converging boundary produces a

In sea-floor spreading, molten material rises from the mantle and erupts

The geological theory that states that pieces of Earth’s lithosphere are in constant, slow motion is the theory of

1

At what point does magma become lava?

1

What is Pangaea?

1

Which of the following is evidence for sea-floor spreading?

1

What technology did scientists use in the mid-1900s to map the mid-ocean ridge?

1

A string of islands known as a(n) _______  can form from the collision of two
oceanic plates.

1

The hypothesis of _______  was that all the continents once were joined as a single supercontinent and have since drifted apart.

1

When continental plates pull apart at a divergent boundary on land, a(n)
_______ forms

1

The process of _______ continually adds new crust to the ocean floor along both sides of the mid-ocean ridge.

1

When you touch a hot plate, the transfer of heat from the plate to your hand is called_______ 

1

One major belt of volcanoes is called the _______ 

1

_______ causes the movement of Earth's plates. 

1

Along a divergent boundary, two plates slip past each other, moving in opposite directions.

1

Alfred Wegener provided evidence from landforms, fossils, and climate in support of his theory of the Continental Drift.

1

If subduction occurs faster than oceanic crust can be created, an ocean will expand.

1

Oceanic crust near the mid-ocean ridge is younger than oceanic crust farther away from the ridge.

1

Volcanoes that form along a mid-ocean ridge occur at a(n) diverging plate boundary.

1

Mid-ocean ridges form the longest mountain ranges on Earth.

2

What feature occurs at X and how does it form?

2

Describe what is happening at point Z in the illustration.

3

Name the three types of evidence geologists have found for sea-floor spreading.

2

Cite evidence from a landform and fossil to support the hypothesis that Africa and South
America were once joined.
