Checkpoint Review 4th 6wks

Match each observation to the correct type of geological evidence: fossil evidence, plate tectonics, or superposition.

Based on Alfred Wegner's Theory

• Fossil evidence

• Rock layers in a canyon show older rocks at the bottom and younger rocks at the top.

• Superposition

• Marine fossils found on a mountaintop.

• Plate tectonics

• Similar rock formations and fossils on continents now separated by oceans.

Which of the following are reasons why Earth's landmasses have changed position over time? (Select all that apply.)

• The movement of tectonic plates beneath Earth's surface

• The rotation of Earth causing continents to shift
  

• Convection currents in the mantle moving tectonic plates

• Wind and water erosion breaking apart continents

Which pieces of evidence support the theory of continental drift and plate tectonics? (Select all that apply.)

• Similar fossils found on different continents that are now separated by oceans

• Matching rock formations on continents that seem to fit together like a puzzle

Match each plate boundary type with its correct everyday object model.

• Two sponges rubbed against each other

• Transform Boundary

• Two sheets of paper pushed together

• Convergent Boundary

• modeling clay pulled apart forming a gap

• Divergent Boundary

Which type of plate boundary is responsible for the formation of the San Andreas Fault in California?

• Convergent boundary – where two plates collide and create mountains

• Divergent boundary – where two plates move apart, forming new crust

• Transform boundary – where two plates slide past each other, causing earthquakes

• where one plate sinks beneath another into the mantle

What is a watershed?

• An area of land where all the water drains into a common body of water

• A large lake that stores rainwater

• A deep underground river that supplies water to cities

• A man-made system of pipes that transports water

Excessive groundwater pumping can lead to which of the following environmental problems?

• The soil becomes compacted, reducing its ability to hold water.

• Underground water levels rise, causing massive floods.

• More freshwater is created, increasing available drinking water.

• The land surface expands and creates new ecosystems.

What happens to the soil when too much groundwater is pumped out over time?

The soil becomes compacted, reducing its ability to store and transport water.
The soil expands and creates more space for plant roots.
More groundwater is created, improving water availability.
The land surface rises due to increased underground space.

• The land surface rises due to increased underground space.

• More groundwater is created, improving water availability.

• The soil expands and creates more space for plant roots.

• The soil becomes compacted, reducing its ability to store and transport water.

How do human activities along the Mississippi River impact the Gulf of Mexico?

• Human activities have no impact on the Gulf of Mexico.

• Agricultural runoff and industrial pollution from the Mississippi River can contribute to water contamination and harm marine life in the Gulf.

• Human activities along the Mississippi River help clean and purify the waters before they reach the Gulf.

• The Gulf of Mexico is too large to be affected by any activities along the Mississippi River.
