What is the principle of superposition in geology?

• The oldest layers of rock are on the top.

• The youngest layers of rock are on the top.

• All layers of rock are the same age.

• Rock layers are randomly arranged.

How do fossils provide evidence for the changes in Earth's surface over time?

• Fossils show that all species have always existed in their current form.

• Fossils indicate that continents have remained in the same position.

• Fossils reveal that different species lived in different geological periods.

• Fossils suggest that Earth's climate has always been the same.

Explain how the movement of tectonic plates can lead to volcanic eruptions.

• Tectonic plates move apart, allowing magma to rise to the surface.

• Tectonic plates move together, preventing magma from reaching the surface.

• Tectonic plates remain stationary, causing magma to cool.

• Tectonic plates move in circles, creating whirlpools of magma.

What is a supervolcano, and how does it differ from a regular volcano?

• A supervolcano is smaller and erupts more frequently.

• A supervolcano is larger and has the potential for more massive eruptions.

• A supervolcano is underwater and erupts silently.

• A supervolcano is made entirely of water.

Which of the following best describes the process of plate tectonics?

• The movement of Earth's plates due to the rotation of the planet.

• The movement of Earth's plates caused by convection currents in the mantle.

• The movement of Earth's plates due to gravitational pull from the moon.

• The movement of Earth's plates caused by the sun's heat.

What evidence supports the idea that Earth's continents were once connected?

• The presence of similar rock formations on different continents.

• The uniform climate across all continents.

• The identical size of all continents.

• The lack of oceanic fossils on continents.

Describe how earthquakes are related to the movement of tectonic plates.

• Earthquakes occur when tectonic plates move smoothly past each other.

• Earthquakes occur when tectonic plates collide and release energy.

• Earthquakes occur when tectonic plates stop moving.

• Earthquakes occur when tectonic plates dissolve.
