1 When tornadoes pass through regions, they can strip the land down to bare soil. Exposing this bare soil could lead to increased —

• soil erosion.
• worm populations in the soil.
• numbers of minerals in the soil.
• ater retention.

The picture below shows the snow-covered Kanaga volcano in Alaska. How could an eruption of this volcano affect local ecosystems nearby?

• It could cause snow to melt, flood, and drown local plants and animals.
• It could decrease the amount of rock at the bottom of the volcano.
• It could increase the amount of sunlight that reaches plants on the volcano.
• It could decrease the number of minerals in soil found around the volcano.

3 The picture below shows Hurricane Sandy as it approached the northeastern part of the Unites States. All of the following could have been effects of Hurricane Sandy EXCEPT —

• A decreased local animal populations, because animals died during the storm.
• B negative human-animal interactions, because animals move toward shelter.
• C dehydration and animal deaths, because of increased temperatures.
• D larger mosquito populations, because mosquitoes lay larvae on standing water.

• B large amounts of precipitation and flooding of coastal areas
• C lower temperatures and slower rates of plant growth
• D high rates of extinction among reptiles and amphibians

• B become more horse-like
• C begin to prey on lions

The picture below shows sand dunes on Padre Island, Texas, in the Gulf Coast Prairies and Marshes ecoregion. The sand dunes most likely formed by —

• B land that slightly uplifted when tectonic plates moved under the beach sand.
• C a primitive river that flowed toward the ocean and carved out the sand dunes.
• strong waves dumping chunks of the ocean floor onto the beach.
