Weather Unit Post-Test 2018-2019

As you travel up into the mountains, you notice discomfort in your ears. This is due to _______.

• the low pressure in your ears.

• the low pressure at the bottom of the

  mountain.

• the low air pressure in the mountains.

• the high air pressure in the mountains.

During the water cycle, the sun's energy evaporates water from the surface of Earth. This water is the source of _______.

• respiration.

• precipitation.

• transpiration.

• ozone depletion.

The climate of Hawaii is cooler than the climate of other places in the same latitudes. This is MOST LIKELY a direct result of ________.

• climate change.

• ocean temperature.

• plate tectonics.

• the Coriolis effect.

The large winds that circle the Earth occur because the equator _______.

• has less energy than the Sun.

• is warmer than the north and south poles.

• is perpendicular to the Suns rays.

• is the place where the Earth bulges slightly.

Scientists say that conditions must be "just right" for a hurricane to start up. Which is the first step of "just right" in the development of a hurricane?

• Cool ocean water replaces warmer surface water.

• Hot dry wind blows from land across the ocean surface.

• Very warm ocean water evaporates into the atmosphere.

• Humid ocean air cools and condenses to form precipitation.

If water is continuously moving through the water cycle, why is it so important to conserve water?

• Most of the water is stored in the oceans.

• It can take decades for water to become drinkable again.

• Industrial pollution speeds up the hydrological cycle.

• Global warming is causing the water to become undrinkable.

A cold air mass that moves through the United States and reaches New York, Kansas, and even South Carolina is air that came from the ___________.

• polar convection region.

• Canadian convection region.

• arctic convection region.

• temperate convection region.

Barometers have long been used to predict the weather. Jay and Jeff were responsible for recording the class weather data each day in March. This particular morning, they tapped the barometer and noticed that the indicator needle did not move. What clue did the barometer give the boys about the up-coming weather?

• The stillness means a tornado is approaching.

• The barometer holding steady means a low pressure is slowly approaching.

• A severe low pressure is coming and bringing a storm.

• The barometer holding steady means present weather conditions should continue.

How would global warming change the water cycle and the climate around bodies of water, like oceans and lakes?

• Warmer temperatures would cause in a drier, hotter climate.

• Warmer temperatures would cause more evaporation and more precipitation.

• Warmer temperatures would cause more precipitation and less run-off.

• Warmer temperatures would cause more evaporation and much less ground water.

How would the global climate be different if more of Earth was covered by land than water?

• The climate would be more extreme than it is today.

• The climate would be more moderate than it is today.

• There would be no winds in the Northern Hemisphere.

• There would be no rainfall in the Northern Hemisphere.
