What is the cooler air rushing down a mountainside called?
- A.
Land Breeze
- B.
Mountain Breeze
- C.
Sea Breeze
- D.
Valley Breeze
Correct Answer
B. Mountain BreezeExplanation
A mountain breeze is the cooler air rushing down a mountainside. During the day, the sun heats up the air on the mountainside, causing it to rise. As the air rises, it creates a pressure gradient, drawing cooler air from higher altitudes down the mountain. This cooler air is known as a mountain breeze. It is the opposite of a valley breeze, which occurs at night when the air on the valley floor cools and sinks down into the lower areas.Rate this question:

Flatline
Correct Answer
B. DoldrumsExplanation
The low pressure area along the equator is called the doldrums. This region is characterized by calm winds and little to no air movement, making it difficult for sailors to navigate. The lack of wind in the doldrums is caused by the convergence of trade winds from both hemispheres. The name "doldrums" comes from an old English word meaning "dull" or "listless," which accurately describes the stagnant conditions experienced in this area.Rate this question:

What front results when a cold front takes the area of a warm front?
- A.
Stationary Front
- B.
Oopla Front
- C.
Sedentary Front
- D.
Occluded Front
Correct Answer
D. Occluded FrontExplanation
When a cold front overtakes a warm front, it creates an occluded front. This occurs when the cold air mass moves faster than the warm air mass, causing the warm air to be lifted off the ground. As a result, the warm air is sandwiched between the cold air ahead and the cold air behind, leading to the formation of an occluded front. This type of front is typically associated with precipitation and often brings cloudy and stormy weather conditions.Rate this question:

Which of these is the best way meteorologists track big storms such as hurricanes?
- A.
Helicopters
- B.
Barometers
- C.
Thermometers
- D.
Doppler Radar
Correct Answer
D. Doppler RadarExplanation
Meteorologists track big storms such as hurricanes using Doppler Radar because it is the most effective method. Doppler Radar uses radio waves to detect and track precipitation, as well as measure the speed and direction of the wind within a storm. This allows meteorologists to accurately predict the path and intensity of the storm, providing crucial information for public safety and emergency response efforts. Helicopters, barometers, and thermometers are not as effective in tracking and monitoring storms of this magnitude.Rate this question:

What process changes a rock's chemical composition to break it down?
- A.
Physical Weathering
- B.
Cyclical Weathering
- C.
Chemical Weathering
- D.
Icicle Weathering
Correct Answer
C. Chemical WeatheringExplanation
Chemical weathering is the process that changes a rock's chemical composition to break it down. This occurs when the minerals in the rock react with water, oxygen, or other substances in the environment, leading to the breakdown and alteration of the rock's structure. Unlike physical weathering, which involves the mechanical breakdown of rocks without changing their chemical composition, chemical weathering involves chemical reactions that cause the rock to decompose and disintegrate over time.Rate this question:
