Hurricane

• Transfer of thermal energy through circular motion caused by heating and cooling of fluids (liquids/gases)

• tropical cyclones that forms in the southern Atlantic along the equator. MUST BE OVER WARM WATER.

• The movement of air as a result of Earths rotation. (Northern Hemisphere it curves to the right)

• The amount of water vapor in the air

Air Pressure

• The force exerted by the atmosphere on Earth’s surface by the weight of the air above.

• Very dense cool dry air. Brings happy weather.

• movement of air from an area of high density and pressure to low density and pressure. Caused by uneven heating of the earth

• Low density air. Brings lousy weather.

Low Pressure

• The force exerted by the atmosphere on Earth’s surface by the weight of the air above.

• Low density air. Brings lousy weather

• Very dense cool dry air. Brings happy weather.

• Transfer of thermal energy through circular motion caused by heating and cooling of fluids (liquids/gases)

El Nino

• Abnormally high surface ocean temperatures off the coast of South America. Causes unusual weather patterns across the globe. It can cause the winds to change directions.

• Abnormally Low surface ocean temperatures off the coast of South America. Causes unusual weather patterns across the Globe.

• tropical cyclones that forms in the southern Atlantic along the equator. MUST BE OVER WARM WATER.

• The movement of air as a result of Earths rotation. (Northern Hemisphere it curves to the right)

based on the weather map, which city will most likely experience decreasing temperatures during the next 24 hours?

• Denver, because it is raining there

• Minneapolis, because a cold front is approaching

• Atlanta, because a warm front is approaching

• Houston, because it is in a high-pressure area.

When watching the local meteorologist on television or when looking at a weather map online, there are often maps with a "L", as seen in the picture included. The "L" represents an area of low atmospheric pressure on the Earth's surface.. What is the most likely occurring in the atmosphere in the area located at the "L" on the map?

• The air is descending at the location causing clear skies

• The air is descending at this location causing cloudy skies

• the air is rising at this location causing clear skies

• the air is rising at this location causing cloudy skies

What is the main cause of global convection currents?

• deforestation

• uneven heating of the Earth by the sun

• the greenhouse effect

• the increase in the number of cities

Energy from the sun is transferred from the Earths surface to the atmosphere, resulting in atmospheric convection currents that produce winds. How do physical properties of the air contribute to the convection currents?

• the warmer air sinks because it is more dense than cooler air

• the warmer air rises because it is more dense than cooler air

• the warmer air sinks because it is less dense than the cooler air

• the warmer air rises because it is less dense than cooler air.
