A student observes that when they leave a cold drink on the table, it eventually becomes warm. What principle does this observation illustrate?

• The drink absorbs heat energy from the table due to convection.

• The drink absorbs cold energy from the air due to conduction.

• Heat naturally flows from the warmer surroundings to the cooler drink due to the Second Law of Thermodynamics.

• Cold naturally flows from the drink to the surroundings due to the Second Law of Thermodynamics.

Explain the atmospheric chemistry of earth's greenhouse gases and their effect on the greenhouse effect, if any.

• Greenhouse gases are composed of carbon dioxide, methane, and water vapor. They allow the sun's rays to penetrate the atmosphere, reach the surface and are reflected back toward the atmosphere, then the greenhouse gases reflect them back to the surface. This traps heat between the surface of Earth and the atmosphere preventing the earth from cooling too much for life to exist.

• Greenhouse gases are composed of methane, carbonic nitrates, and water vapor. They prevent the sun's rays from penetrating the atmosphere to reach the surface instead they are reflected back to the surface. This releases heat between the surface of Earth and the atmosphere.

• Greenhouse gases are composed of carbon dioxide, methane, and nitrogen. They allow the sun's rays to get through to reach the surface and are reflected back and forth between atmosphere then back to the surface. This keeps heat between the surface of Earth and the atmosphere preventing the earth from cooling too much for life to exist.

• Greenhouse gases are composed of nitrogen, oxygen, carbon dioxide, methane, and water vapor but they have no effect on earth's greenhouse effect.

Match the following terrestrial biomes to their characteristics:

• temperate deciduous forest

• Four distinct seasons with precipitation evenly distributed through the year. Common plants and animals include oak, hickory, deer, bears and many songbirds.

• temperate grassland

• This biome in the northwestern USA has a cold winters and hot summers with abundant rainfall to support very tall trees like redwoods and sequoias.

• Desert

• A dry, barren area with little precipitation.

• tundra

• The hot and dry summers, along with low and dense plant growth makes the risk of fire high in this area. Prairie dogs are found here.

• temperate rainforest

• Permanently frozen soil, dwarf forms of plants, little precipitation, little decomposition.

Match the following Aquatic biomes with their characteristics:

• Stream

• A small, narrow body of flowing water.

• Ocean

• A large, high salinity body that makes up an estimated 97% of the world’s total water; has major impact on temperature, weather, and the food supply for earth's organisms.

• River

• A small body of still water formed naturally or by artificial means.

• Estuary

• Where water with low and high salinity meet; high in nutrients creating lots of biodiversity.

• Pond

• A large natural stream of water flowing in a channel to the sea, lake, or another river.
