Which answer choice properly explains why Location "Y" will experience the GREATEST amount of erosion over time and Location "Z" will experience the LEAST amount of erosion over time?

• Location "Y" will experience the greatest amount of erosion over time because it has the gentlest slope

  Location "Z" will experience the least amount of erosion over time because it has the steepest slope

• Location "Y" will experience the greatest amount of erosion over time because it has the steepest slope

  Location "Z" will experience the least amount of erosion over time because it has the gentlest slope

• Location "Y" will experience the greatest amount of erosion over time because it has the highest elevation

  Location "Z" will experience the least amount of erosion over time because it has the lowest elevation

• Location "Y" will experience the greatest amount of erosion over time because it has the lowest elevation

  Location "Z" will experience the least amount of erosion over time because it has the highest elevation

Convection is the process of cool, dense material sinking and warm, less dense material rising over and over. An 8th grade science student attempts to model convection currents on Earth using a pot of boiling water. Which answer choice below best explains a limitation of using a pot of boiling water to model convection currents on Earth?

• The density of warm and cool material are reversed in a pot of boiling water

• The achievable temperature for a pot of boiling water is not high enough to cause convection to occur

• In a pot of boiling water, material with more density rises and material with less density sinks

• A pot of boiling water is heated by the burner below it, while Earth's atmosphere and oceans are heated by the Sun above them.

One of the major ways oceans contribute to weather systems is that the oceans -

• provide a diverse habitat for many organisms.

• store and transport the Sun’s heat energy from the Equator to the poles.

• experience changes in amounts of dissolved salt.

• reach depths that can be as much as 12,000 meters.

What 3 pieces of evidence did Wegener use to support his theory of Continental Drift, wherein he concludes that each continent used to be connected to form one supercontinent named Pangea? Mark all THREE.

• Coastlines of multiple continents seemed to be able to fit together

• Matching glacial deposits and rock formations were found on multiple continents

• Evidence of land bridges connecting multiple continents was discovered

• Matching plant and animal fossils were found on multiple continents

• Evidence existed that the coastlines of multiple continents were eroding at the same rate

The satellite image below shows a portion of the Namib Desert in Africa. This is an ancient, sandy desert with dunes that can be up to 305 m tall. The Namib Desert extends inland from the Atlantic Ocean between 80 km and 200 km and receives only 5 mm to 76 mm of rain each year. A satellite picture of this same area taken weeks before shows that the shape and location of some sand dunes have changed. Which of these most likely caused the changes in the dunes?

• Ocean waves

• Flowing rivers

• Blowing wind

• Crustal uplift
