Recurrent Weather

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.

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 one condition that is necessary for a hurricane to form?

• warm ocean water

• a strong cold front

• cold ocean water

• a strong warm front

Hurricanes and similar storm systems begin over oceans. The map shows average surface temperatures of the ocean in the summer. Based on the map, which area probably produced the most violent storm systems?

• area 1

• area 2

• area 3

• area 4

What role does the ocean play in the Texas weather? (Think about Tuesday's warm up question Cali vs. Florida )

• Precipitation that falls on Texas originates from water evaporated from oceans.

• waves along the Texas coast create warm fronts that cause changes in the weather

• Hot and dry conditions in the Texas panhandle are cause by uneven heating of the ocean surface

• High pressure air masses over Texas originate as high pressure air masses over the Atlantic Ocean.

Hurricanes must have an energy source to form and grow. From where does this energy come?

• High air pressure

• warm ocean waters

• The Earth's rotation on its axis

• warm air rises and pulls cooler air into it
