Earth Quiz

Convergent boundaries are areas where plates move toward each other and collide, causing uplift in the crust. Which crustal feature formation is related to this process?

• Oceanic ridges

• Strike-slip fault

• Rift zones

• Mountain ranges on land

How does temperature affect deep ocean currents?

• The sun warms water near the surface, which is less dense than cold water

• The sun warms water near the surface, which is more dense than cold water

• The sun warms water deep in the ocean, which is less dense than cold water

• The sun warms water deep in the ocean, which is more dense than cold water

• The animals were carried on boats as people moved to new areas

• The animals migrated across the ocean in search of food

• The continents were once connected

• There were no oceans during the time these animals lived

A group of students models crustal movement to understand stress caused by plate movement. The students demonstrate compression by squeezing a piece of aluminum foil with equal pressure from both hands. What type of crustal feature is the group most likely forming?

• A divergent boundary that forms an ocean ridge

• A convergent boundary that forms a volcano

• A transform boundary that forms a fault line

• A divergent boundary that forms a volcano

Which statement best describes the effect of snow on the mountains over many years?

• The mountains will increase in height due to deposition of sediment from snow on the mountain tops

• Weathering will occur because snow melting and refreezing will break apart rocks

• Erosion will occur because snow melting and refreezing will break apart rocks

• The mountains will remain unchanged due to the snow

• Warm front

• Occluded front

• Cold front

• Stationary front

Which conditions are necessary to form thunderstorms?

• Warm ocean currents

• High ocean winds

• Cold ocean currents

• Light ocean currents

Seafloor spreading causes the continents of South America and Africa to move farther apart each year. What type of plate boundary causes this crustal feature?

• Subduction Zone

• Transform boundary

• Convergent boundary

• Divergent boundary

Seafloor spreading and rift valleys occur at _________ plate boundaries

• Convergent
• Divergent
• Transform
• Subduction Zones

A mid-ocean ridge is located at the boundary of two tectonic plates. Which diagram correctly models the relative plate motion on each side of a mid-ocean ridge?

• A

• B

• C

• D
