The formation of tornadoes requires the most powerful of all thunderstorms, called supercells, that you can see here. These thunderstorms, which account for less than 10% of all thunderstorms, usually form in the United States during the spring, between the Rocky and Appalachian Mountains. Supercells differ from average thunderstorms in that they develop internal rotating features known as mesocyclones.
What conditions between The Rocky and Appalachian Mountains spark the formation of tornadoes within supercells?
A) Air masses are isolated because of the two mountain ranges. As they meet, moist air tends to fall below the dry air and this causes thunderstorms. B) Two opposing continental air masses meet in the central United States. As they meet, the air masses tend to swirl around each other, causing a vortex to occur.
C) Warm, moist air moving north from the Gulf of Mexico meets cooler, drier continental air. The warm air rises and cools causing the moisture in the air to condense.
D) When cumulus clouds becomes very large, the water in them becomes large and heavy. Raindrops start to fall through the cloud when the rising air can no longer hold them up.
C) Warm, moist air moving north from the Gulf of Mexico meets cooler, drier continental air. The warm air rises and cools causing the moisture in the air to condense.

A) The differential heating of land and sea by the Sun results in the movement of air.
B) Hot air from the sea blows over the land because there is a high pressure area over the sea.
C) Cold air blows from the land over the sea because there is a low pressure area over land.
D) Air blows from land over the sea because of the rotation of Earth on its axis.
A) The differential heating of land and sea by the Sun results in the movement of air.

Karst topography is any region where the terrain has been dissolved by the action of water. These areas are composed of carbonate rocks, such as dolomite and limestone, or have a high concentration of evaporites, such as salt and gypsum. When slightly acidic rainwater falls to Earth and becomes the groundwater that flows over limestone, we see the Karst topography illustrated form. Explain how this happens.
A) Karst topography can be the result of physical weathering when groundwater causes limestone bedrock to dissolve in the acidic solution to create carbon dioxide and water from the carbonate rocks. B) Karst topography results when slightly acid groundwater chemically weathers the limestone. The acidic water reacts with the calcium carbonate in the limestone creating calcium salt, water and carbon dioxide.
C) Karst topography is the result of erosion. Acidic groundwater, moving through bedrock, dissolves away the rocks particles. The result is the cracking and breaking of the bedrock forming caves and sinkholes.
D) Karst topography occurs when groundwater causes the limestone to dissolve physically, similar to the way we make a solution of salt and water. The limestone particles get smaller and smaller until the bedrock crumbles.
B) Karst topography results when slightly acid groundwater chemically weathers the limestone. The acidic water reacts with the calcium carbonate in the limestone creating calcium salt, water and carbon dioxide.

In the semi arid regions of China, the country's inhabitants have practiced water harvesting for generations. Water harvesting is the process of collecting rainfall and/or runoff for later use. How does this water conservation method help the environment?
A) Water harvesting causes drought-like conditions the rest of the year.
B) Harvesting water during the rainy season has damaged the ecosystem by killing some of the organisms.
C) By collecting run off during the rainy season for future irrigation increases the agricultural production.
