When the jet stream brings polar air to the southern part of the United States, what happens to the weather in the northern United States?
The temperatures get colder.
A. to illustrate how water travels from Earth's surface into the atmosphere and back to Earth's surface again
When the Moon is in its first quarter and third quarter phases, the gravitational forces of the Sun and the Moon pull at 90 degree angles from one another. This means that when the Moon is in its first quarter and third quarter phases,
high tides are at their lowest levels which is called neap tides.
Why did the scientists use a two-dimensional earth layer model instead of another type of model to study the earth?
The layers of Earth are the same from every angle, so the scientists do not need a three-dimensional model.
The Midwestern United States is home to "Tornado Alley," a portion of Texas, Oklahoma, Kansas, and Nebraska. Tornado Alley is located where the jet stream drives cool, dry, high-pressure air masses from the deserts and mountains of the West toward the East Coast. With which type of air mass do these high-pressure fronts collide to create so many tornadoes?
moist, warm, low-pressure air masses from the Gulf of Mexico.
Think. Which city receives its freshwater supply directly from the Hetch Hetchy Aqueduct? A. San Francisco or B. Santa Barbara
Describe a way the hydrologic cycle model can best be used?
It can be used to study the entire water system on a manageable scale.
From which ocean floor destination would a sonar signal take the longest amount of time to return to the receiver?
What is most likely to cause a low pressure system that leads to hurricanes?
High amounts of water vapor condense into clouds and release heat.
Shannon lives in an area of New York that frequently has air temperatures below freezing in winter. Windy conditions also occur and are caused by air that originates in Canada and blows across the Great Lakes. Which of the following will occur with low winter temperatures as the air mass moves from Canada to New York?
Moisture collected from the lake may be released as snow over the cold land.
Which set of conditions will result in the highest rate of evaporation? A. high temperatures, strong winds, low humidity, clear skies or B. low temperatures, strong winds, high humidity, clear skies
high temperatures, strong winds, low humidity, clear skies
What is the name of the warm ocean current that travels near Savannah and the Gulf of Mexico?
What describes the inner core of Earth?
It is dense, composed primarily of solid iron, is under the most pressure with the highest temperatures, and is 1250 kilometers thick.
Warm air moves upward, while cold air moves downward. Which of the following best explains this pattern of heat transfer?
Differences in density caused by temperature differences create buoyant forces.
Why do the bodies of water in Georgia evaporate more quickly than the bodies of water off of the New England coast?
The temperature of the water is warmer along the Georgia coast.
What happens to polar ice caps if the Sun's energy gets stronger?
The ice will become water, then the water will become vapor.
What is a longshore current?
Amelia is making a three-dimensional model of Earth's layers. She is gathering materials, but is not sure what to use for the crust layer. Which of the following would best represent the properties of Earth's crust in a model? A. a thin, rough material or B. a smooth, square block
a thin, rough material
Which of the following statements explains why the tops of mountains are cold?
Air is cooled as it moves to areas of lower pressure at high elevations.
Corbitt takes a bottle of juice out of the refrigerator. He notices that water begins to form on the outside of the bottle. Which of the following explains why the water started to form?
Condensation forms on the bottle because the room is warmer than the bottle.
A lake participating in a part of the water cycle with the arrows pointing upward. What is happening when the arrows are pointing upward at the first phase?
Energy from the Sun is heating the water in the lake, causing some of it to evaporate into water vapor.
Why does the inner core of Earth remain solid even though it is very hot?
The pressure is so great at the inner core that it causes atoms to push together.
