Weather and Climate

What angle would Earth's tilt need to be in order for there to be NO seasons on Earth?

• 0^o
• 45^o
• 60^o
• Earth's tilt does not offset the seasons.

On a summer day which clouds are most likely to bring rain?

• thin, fluffy clouds
• red clouds at sunset
• thick, dark-gray clouds
• clouds that look like white sheep

Which change would result in the same s eason year round, everywhere on Earth?

• Earth moving at least twice as fast in its orbit as it does now
• enlarging the diameter of Earth's orbit until it is much farther from the Sun
• straightening the tilt of Earth's axis to be 90^o to the plane of Earth's orbit
• changing Earth's orbit so it would always be the same distance from the Sun

The average temperature in Atlanta in June is 25^o C, but the average temperature in December is 7^o C. Why is the average temperature in Atlanta higher in June than in December?

• The Sun is hotter during June than it is during December.
• Earth is closer to the Sun in June than it is during December.
• Earth's axis is tilted so that Atlanta gets more direct sunlight in June than in December.
• The atmosphere in Atlanta absorbs more heat from sunlight in June than in December.

Which statement describes why the Earth has seasons?

• Its axis is titled as it revolves around the sun.
• The distance changes as it revolves around the sun.
• The moon revolves around it.
• The sun's axis is tilted.

An air mass forms over the Gulf of Mexico and moves northeast across Georgia. What weather conditions are likely to prevail in Georgia?

• cool and dry
• cool and humid
• warm and dry
• warm and humid

Which is the warmest climate zone?

• Arctic Zone
• Temperate Zone
• Tropical Zone
• Intermediate Zone

Cold air masses that form at high latitudes are called

• polar air masses.
• continental air masses.
• warm air masses.
• maritime air masses.

In some years there are more hurricanes than usual. This is probably because

• the ocean is warmer than usual.
• the ozone layer is very thin.
• there are more windy days than usual.
• the gravitational pull of the Moon is stronger.

At the seashore late in the afternoon on a hot, sunny day, a person often feels a strong breeze coming in from the ocean. Which of the following is the reason for the breeze?

• The pounding waves generate air currents.
• The warm air over the ocean rushes in to replace the cool air that rises over the land.
• The heavy, cool air over the ocean rushes in to replace the warm air that rises over the land.
• There are no clouds to block the wind coming in from the ocean.
