Which of the following is the best description of radiation?
D. the emission of energy in the form of rays or waves
Water is cooler near the poles and warmer near the equator. Movement of cooler and warmer water from these regions moderates the global climate. Which of the following describes the movement of water between the poles and the equator?
The pattern of _______ in an area over a long period of time is called _______.
Solar energy received by the Earth's surface causes the Earth's surface to heat up during the day. Which of the following heat transfer mechanisms is the main cause of the surface gaining heat?
Mr. Stein uses a model because
A. the real molecule is too small to easily observe.
Which of the following is the best description of conduction?
D. The transfer of heat through touch.
D. The transfer of heat through touch.
The Gulf Stream passes from the Gulf of Mexico, northward along the coast of eastern North America, and eastward toward Ireland, the United Kingdom, and Scandinavia. Without the Gulf Stream, these regions would be colder than they are. How does the Gulf Stream keep these regions warm?
A. It brings warm water, which heats the overlying air.
Each day, changes take place in the atmosphere. All these frequent changes are called _______.
During the day, when the Sun is shining, the ground gets warm mainly as a result of...
There are many different types of scientific investigations, including controlled experiments, observational field studies, the collection of specimens, and model-building. Which type of investigation is best used to study global weather patterns?
Convection currents, resulting from uneven heating of the Earth's surface, cause _______ to form.
The California current is an ocean current that moves cold water from the north along the west coast of the United States. The main effect of this current is to make the climate of the west coast .
D. cooler
Water in the atmosphere typically returns to the surface of the Earth through the formation of clouds and precipitation. This means that the cycling of water from the atmosphere to the hydrosphere would be most likely to cause
When sunlight strikes the ground it warms the ground and the air near it. The warm air near the ground then rises as it expands. What does this process typically result in on the ground?
Models can be helpful in scientific investigations because
The atmosphere is heated both by the Sun and by the Earth's surface. Water radiates heat differently than land, so the air temperature over the ocean is usually different than the air temperature over land.
The difference in air temperature over land compared to over water causes convection currents in the atmosphere. How would a person at the beach experience these convection currents?
The Sun heats Earth's atmosphere unevenly. This causes convection currents to move in large circles in the atmosphere.
What is the result of convection currents in the atmosphere?
Areas of the Earth near the equator receive large amounts of solar energy. How does this lead to increased rainfall?
The atmosphere flows in large convection currents.
What happens during atmospheric convection?
Explain one way models are used while discussing weather.
- Weather maps
- Models of cold and warm fronts
- Pictures of weather systems
- Global climate patterns
- Wind maps and models
- Global ocean current models
Select all the correct answers.
Some areas of the Earth receive more solar radiation than others. Which of the following results from the Sun's uneven heating of the Earth?
A. ocean currents
B. mountain height
C. climate
D. weather
A. ocean currents
C. climate
D. weather
At night in coastal regions, land breezes often develop. Which of these best explains why they develop?
A jet stream is a belt of wind in the upper atmosphere that blows around the Earth from west to east.
How is the jet stream related to the wind direction on the ground?
Part of the Sun's energy that reaches the Earth's surface is absorbed by land and water as heat. The Earth's surface then releases heat back to the atmosphere.
Which of the following is true about this solar energy that is absorbed and released by Earth's surface as heat?
Dr. Ray has developed a new way to remove oil from wetlands in the event of an oil spill. To test his new process, Dr. Ray builds a scale model of a wetland in his lab and pours a small amount of oil into it. He then observes the rate at which his process is able to remove the oil from the model.
Why did Dr. Ray use a model?
