Plate tectonics, earthquakes, volcanoes

The theory of plate tectonics came from the idea of continental drift, which was proposed by Alfred Wegner.

The fossils in line 4 are _________ the ones in line 1 of the diagram.

Large areas of Virginia were once covered by seawater. The fossil MOST LIKELY found in Virginia is

This is a geologic event that occurs when tectonic plates are displaced violently.

What is the main method of heat transfer from the core to the crust of Earth?

This is the breaking down of rocks, soils, and minerals through direct contact with the earth's atmosphere.

This is the movement of soil, mud and rock due to the downward movement of wind, water or ice.

Which geological features MOST LIKELY prompted the development of the theory of plate tectonics?

______________ are caused by earth's internal heat sources.

This is a landform that is formed by the eruption of magma through a vent from the interior of the earth.

This landform is the result of water and wind erosion. What do we call this landform?

Marble is formed when intense heat and pressure is applied to limestone. What type of rock is marble?

What type of rock forms when magma deep below the Earth's crust cools off and hardens.

This is the geologic theory where the cooler surface of the earth move slowly over the hotter layer underneath.

If scientists were able to stop the tectonic plates from moving, people on Earth would no longer have

What was Pangaea?

There are 3 types of plate boundaries. Which choice is NOT a type of plate boundary?

Occurs at mid-ocean ridges where oceanic crust is formed by volcanic activity and slowly moves away from the ridge.

How many seismograph stations are needed to determine the exact epicenter of an earthquake?

Which of these BEST describes the concept of the rock cycle?

The convection shown in the diagram is powered by heat from which part of the Earth?

What causes sedimentary rock to change into metamorphic rock?

Which instrument is used to capture the vibrations caused by an earthquake?

the San Andreas fault and it is an example of a __________ fault or boundary.

what type of rock could be formed from the weathering and erosion of metamorphic rock?

The continental crust is _________ than the oceanic crust and seems to "float" on the mantle.

This is an area where two tectonic plates move towards one another, with one plate sliding underneath the other plate.
