Exam 8: Earth From the Inside Out

Based on their origins, rocks can be divided into three distinct families: _______, sedimentary and metamorphic.

What is an oceanic plate and how does it relate to a continental plate?

What holds rocks together?

Through the rock cycle, if a metamorphic rock goes through heating and then melts to become magma, it will eventually cool and turn into:

The continents and ocean basins are located in the:

Rocks closer to the spreading centers in the oceans (see Figure below)are older than the rocks farther away from the spreading center.

The three types of rocks are igneous, sedimentary, and extrusive.

The rocky, outermost part of the Earth, comprising the upper part of the mantle and the crust, is known as the _______.

What hypothesis is Alfred Wegener known for, and what evidence supported his hypothesis?

The deepest portion of an ocean basin is always in the middle.

Why is the area where the ocean meets the land not necessarily the edge of the continent?

Marble forms as a metamorphic product of what original rock?

Which of the following terms best describes the rocky outer layer of the Earth?

Because of the extreme heat and pressure required, metamorphic rocks are generated most often:

Felsic minerals tend to be:

What's the difference between a rock and a mineral?

Sample _____ is of a rock whose original sedimentary or igneous form and mineral assemblage have been changed as a result of exposure to high temperature, high pressure or both. This type of rock is referred to as a metamorphic rock.

How did the presence of certain fossils support Wegener's idea of continental drift?

Describe the evidence Wegener used to reconstruct Pangaea.
