Plate Tectonics Topography Maps

Rift Valleys can form when fractures in Earth’s crust widen. The valley walls slowly move at a rate of only a few millimeters a year. Which of these best describes the type of tectonic activity that forms rift valleys?

• Rift valleys form where a continental plate moves under an oceanic plate.

• Rift valleys form where a plate slides horizontally past another plate.

• Rift valleys form where two plates move away from each other.

• Rift valleys form where an oceanic plate moves under another oceanic plate.

A mid-ocean ridge seperates the Pacific plate and the Nazca plate off the western coase of South America. Which statement be describes the relative motions of the Pacific and Nazca plates?

• The Pacific and Nazca plates are both moving to the east.

• The Pacific and Nazca plates are both moving to the west.

• The Pacific plate is moving to the west, and the Nazca plate is moving to the east.

• The Pacific plate is moving to the east, and the Nazca plate is moving to the west.

The image shows a plate boundary. Arrows have been added to indicate the movement of the plates. What plate boundary feature is shown above?

• A valley forming at an active divergent boundary

• A volcano formed by an active transform boundary

• A fault forming at an active transform boundary

The diagram below shows a model of the movement of two tectonic plates. When the plates collide one plate often moves below the other plate. The rising magma that can result in this type of plate movement may produce -

• fossil layers

• deep-sea sediment

• seafloor spreading

• volcanic islands

This topographic map shows the location of a park range at Point X when a message is received that an injured hiker needs help at Point Z. Which of these is the closest to the difference in elevation between the locations of the ranger and the injured hiker?

• 450 m

• 2,050 m

• 910 m

• 3,650 m

A student stands at the point marked X on the topographic map below. What height in meters must the student climb in order to reach the top of the hill?

• 303 m

• 50 m

• 53 m

• 253 m

Geologists think that the movement of Earth’s plates is caused by -

• conduction currents

• convection currents

• subduction

• Earth’s magnetic field

Which is the highest elevation on the contour map below?

• 80 m

• 57 m

• 85 m

• 75 m

Using the Plate Boundaries Diagram, what is happening at location Z?

• Since granite is denser than basalt, the older crust is subducting.

• Since granite and basalt have equal densities, the younger one is subducting.

• Plate B (granite) is plunging beneath plate C (basalt) and melting in the asthenosphere.

• Plate B (basalt) is plunging beneath plate C (granite) and melting in the asthenosphere.
