Section 3-1 & 3-2 Group Quiz (Version A)
1a. This is an area of volcanic activity created by a weakened area of the earth’s crust.
2a. It contains the oldest rocks known.
3a. It is located where magma rises to the surface of the oceanic crust.
4a. It creates composite volcanoes from the melting of low-density crust.
5a. It is the longest mountain chain in the world, but most of it is under water.
6a. They intersect mid ocean ridges and rift valleys.
7a. It existed about 200 million years ago.
8a. It floats on top of the asthenosphere (the liquid part of the mantle).
9a. This ocean feature can be as deep as seven miles below sea level.
10a. New, less dense oceanic crust creates this oceanic feature.
11a. He came up with evidence to support that the continents at one time formed a super continent.
12a. This process creates ocean basins.
13a. It is a plate boundary.
14a. There is no evidence of it being any older than 200 million years.
15a. This theory was formed after the ocean floor was mapped and studied.
Section 3-1 & 3-2 Group Quiz (Version B)
1b. This area is usually associated with shield volcanoes and slow, quiet eruptions.
2b. It is generally very thick.
3b. Shallow focus earthquakes occur just below this ocean feature.
4b. This process occurs when oceanic and continental plates collide (or oceanic and oceanic plates collide).
5b. It is a plate boundary.
6b. They give shape to the mid ocean ridges.
7b. Evidence of fossils and coal deposits support its existence.
8b. It is divided into many plates that cover the surface of the earth.
9b. It is located at a plate boundary.
10b. This ocean feature is located on either side of a rift valley.
11b. He was a meteorologist by occupation.
12b. New ocean crust is created.
13b. It surrounds the largest lithospheric plate, the Pacific Plate.
14b. It can get subducted due to its high density.
15b. This theory includes the processes of ocean floor spreading and subduction.
Section 3-1 & 3-2 Group Quiz (Version C)
1c. These volcanic areas are not located on plate boundaries.
2c. It can not be subducted because of its low density.
3c. It is located at a plate boundary.
4c. Oceanic crust is destroyed.
5c. It splits the Atlantic Ocean in half.
6c. Earthquakes occur along them.
7c. It included all of the continents of today.
8c. It includes the top of the mantle.
9c. It is located at a subduction zone.
10c. The Mid-Atlantic Ridge is an example of this oceanic feature.
11c. He died on an expedition to Greenland collecting evidence for his theory.
12c. Old, more dense ocean crust is pushed away.
13c. It is the most active earthquake and volcano zone.
14c. It is thin.
15c. This theory states that the earth’s crust is divided into many plates that move.
Section 3-1 & 3-2 Group Quiz (Version D)
1d. The Hawaiian Islands were formed by it.
2d. It basically floats on top of the mantle (asthenosphere)
3d. It is a low-lying area of oceanic crust that is surrounded on both sides by mid ocean ridges.
4d. Deep ocean trenches are associated with this process.
5d. New ocean crust is created along it.
6d. They are a type of fault.
7d. It was nicknamed a “super continent”.
8d. It includes either oceanic or continental crust.
9d. It is considered to be the deepest parts of the ocean.
10d. These features are associated with ocean floor spreading.
11d. He came up with the theory of continental drift.
12d. This process is associated with mid ocean ridges and rift valleys.
13d. It contains many subduction zones.
14d. It gets created at mid ocean ridges and rift valleys.
15d. This theory incorporates evidence from the theory of continental drift.
