Earth Science Quest #2 Review

Earth's crust and upper mantle are broken into 7 large and 8 smaller pieces called

• faults
• tectonic plates
• trenches

The movement of tectonic plates is caused by

• convection currents in the mantle.
• the rotation of the Earth.
• the gravitational pull of the moon.

Which of the following is NOT true about Earth's magnetism?

• Studies show that Earth's magnitism has only flipped once.
• When rocks form from cooling lava, the magnetic pattern is "frozen" into the rocks.
• This was evidence that helped support the idea that older rocks are found farther away from the mid ocean ridge.

The reptile Lystrosaurus has been found in Africa, India, and Antarctica. This evidence helps support the idea that

• the continents have always been the same place as they are today.
• the continents were once covered by ice.
• the continents use to be together and have drifted over millions of years.

What technology did scientists use in the mid 1930's to map the mid-ocean ridge during WWII?

• satellites
• sonar
• deep-sea diving

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

• at the north and south poles.
• in deep ocean trenches.
• along mid-ocean ridges.

The process by which the ocean floor sinks beneath a deep-ocean trench and back into the mantle is knows as

• subduction
• conduction
• continental drift

The "new" theory that proved Alfred Wegener was a "brilliant man" is

• convergent boundaries
• divergent boundaries
• transform boundaries
