Plate Tectonics/Topography

Which type of plate boundary would cause folded mountains to form? 

• transform
• convergent
• divergent
• subduction

The Great Rift Valley in Africa and the Mid-Atlantic Ridge were both created by this type of plate boundary. 

• divergent
• convergent
• transform
• subduction

What drives tectonic plate movement? 

• gravity
• coriolis effect
• convection currents
• the earth's magnetic core

Transform boundaries are most likely to produce what phenomenon?

• volcanoes
• deep sea trenches
• underwater mountain ranges
• earthquakes

When an oceanic plate and a continental plate collide, which one will subduct? 

• oceanic
• continental
• neither
• both

Most geologists rejected Alfred Wegener's idea of continental drift because...

• it did not agree with their current theory
• Wegener was interested in what Earth was like millions of years ago
• Wegener used several different types of evidence to support his hypothesis
• Wegener could not identify the force that moved the continents

In Seafloor Spreading, molten material rises from the mantle and erupts or flows out 

• along the edges of all the continents
• along mid-ocean ridges
• in the deep ocean trenches
• in the north and south poles

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

• convection
• continental drift
• subduction
• conduction

When two continental plates collide,

• an ocean is formed
• mountains are formed
• rift valleys are formed
• one plate subducts under the other one

If we compare the temperature and pressure of the Earth’s mantle to the core, what differences can we expect as we move downward into the Earth?

• Both the temperature and pressure increase.
• Both the temperature and pressure decrease.
• The temperature increases and the pressure decrease.
• The temperature decreases and the pressure increases.
