The Changing Earth Unit 2 Assessment Review

Earth's geosphere is always changing. Scientists explain the timing of these changes as...

• Uniformitarianism ONLY because of slow changes over a long period of time.

• Catastrophism ONLY sudden drastic events.

• BOTH uniformitarianism and catastrophism.

Theory that Earth changes ONLY because of slow changes over long periods of time.

• Uniformitarianism

• Catastrophism

Theory that Earth changes ONLY because of rapid sudden events.

• Catastrophism

• Uniformitarianism

Volcanic eruptions & asteroid impacts are examples of this time of events...

• Uniformitarianism

• Catastrophism

Mountains slowly being weathered and eroded away over millions of years is an example of...

• Catastrophism

• Uniformitarianism

The movement of plate tectonics to form mountains, volcanoes or cause earth quakes are an example of...

• Unifromitarianism

• Catastrophism

Weathering and erosion of rocks on Earth's surface is driven by this type of energy...

• chemical

• kinetic

• geothermal

• thermal

• Sedimentary

• Metamorphic

• Igneous

Which event(s) in the formation of Table Mountain was driven by thermal energy?

• Erosion of sides of mountain around the dried lava flow.

• Tectonic plates moving towards each other to make the mountain.

• The volcanic eruption that sent lava down the ancient river bed.

Which event in the formation of Table Mountain was driven by geothermal energy?

• Tectonic plates moving towards each other creating the mountain.

• Volcanic eruption sending lava down the ancient river bed.
