What does the principle of superposition state about sedimentary rock layers?

• The oldest layers are on the top.

• The youngest layers are on the bottom.

• The oldest layers are on the bottom.

• All layers are the same age.

Describe how the discovery of similar fossils in different continents supports the theory of plate tectonics.

• It suggests that the continents were once connected and have since drifted apart.

• It indicates that the continents have always been in their current positions.

• It shows that the continents are moving closer together.

• It proves that the continents are shrinking.

Which of the following best describes seafloor spreading?

• The process of oceanic crust being destroyed at deep-sea trenches

• The formation of new oceanic crust at mid-ocean ridges

• The movement of continents over the ocean floor

• The erosion of oceanic crust by ocean currents

How does the presence of marine fossils on mountain tops provide evidence for the changing Earth?

• It shows that mountains have always been above sea level.

• It indicates that these areas were once underwater.

• It proves that marine life can survive on land.

• It suggests that mountains are shrinking.

Evaluate the role of earthquakes in providing evidence for the movement of tectonic plates.

• Earthquakes occur randomly and do not provide evidence for plate movement.

• Earthquakes are concentrated along plate boundaries, indicating movement.

• Earthquakes only occur in the middle of tectonic plates.

• Earthquakes are caused by weather changes.

Which of the following is NOT a type of plate boundary?

• Convergent

• Divergent

• Transform

• Static

How does the concept of superposition help scientists determine the relative ages of rock layers?

• By identifying the chemical composition of the rocks

• By determining the absolute age of the rocks

• By comparing the position of rock layers, with older layers below younger ones

• By measuring the thickness of the rock layers
