Ocean Currents

• Affect climate by moving warm and cold water across the earth.

• Have no impact on climate.

• Only affect marine life.

• Are caused solely by wind patterns.

Pollution

• Contamination of the environment by harmful substances.

• Improvement of air quality through natural processes.

• Reduction of waste in landfills.

• Increase in biodiversity in urban areas.

Igloos

• Built by the Inuit of Nunavut, Canada from existing ice.

• Constructed by the Inuit of Greenland using snow and wood.

• Made by the Inuit of Alaska from bricks and mortar.

• Created by the Inuit of Canada using modern materials.

Prevailing Winds

• Circulate about the Earth in a general pattern, and can carry aspects of climate beyond an expected line of latitude.

• Are stationary and do not affect climate patterns.

• Only occur in the tropics and have no impact on other regions.

• Are caused solely by ocean currents and have no relation to atmospheric conditions.

Desertification

• A process where animals overgraze leading to arid conditions.

• A method of irrigation used in dry areas.

• The cultivation of crops in desert regions.

• A type of soil erosion caused by wind.

Acid Rain

• Precipitation that is always pure water.

• Precipitation that contains various levels of acidity due to air pollution mixing with moisture.

• Precipitation that only occurs in the summer months.

• Precipitation that is beneficial for plant growth.

Temperature

• How hot or cold it is at a particular time or over a gradual period of time.

• The measure of the average kinetic energy of particles in a substance.

• The amount of heat energy required to raise the temperature of a substance.

• The degree of hotness or coldness measured on a specific scale.

Stilt Houses/Pile Dwellings

• Housing that is elevated above ground level.

• Housing built on solid ground.

• Housing that is underground.

• Housing made of straw and mud.

Precipitation

• The process of water vapor condensing into liquid water droplets.

• The collection of moisture in the air, which produces rain, sleet, hail, or snow, depending on atmospheric conditions.

• The evaporation of water from the surface of the Earth into the atmosphere.

• The movement of water through the soil and into the groundwater system.

Polders

• Low-lying areas where humans have pumped water out of lakes or river basins to access the fertile soil underneath for the purpose of agriculture.

• High-altitude regions where water collects in natural basins.

• Coastal areas that are prone to flooding and erosion.

• Desert regions that have been artificially irrigated for farming.
