Question

the ____ is a narrow current of air that moves around the northern and southern hemisphere of the earth in wavelike patterns. the jet stream generally flows from __ to __. the __ is the temperature at which the water vapor in the air condenses and becomes liquid. when heated air rises and cooler air flows in to fill the lower pressure area created by the rising air, this flow is called __. __ is the difference in pressure between neighboring areas of high pressure and low pressure. the rate at which the earths surface is heated by solar radiation is called __. __ transfers heat energy without changing the temperature of anything between the source of energy and the object heated. __ is the condition of the atmosphere at a given time and place. the __ of the air is important because the heat energy within the atmosphere generates all the earth’s weather processes. __ is the total energy of motion of all the molecules in a substance. __ is the measure of that molecular motion on a scale devised by scientists. __ is the force exerted on you by the weight of tiny particles of air. although air molecules are invisible, they still have __ and take up __. __ are used to measure the current air pressure at a particular location. the atmosphere is composed of 78% __ and 21% __. name the two main regions that compose the earth’s atmosphere. __ clouds usually form when warm, moist air is forced upward. the clouds that produce heavy thunderstorms in summer are a form of __ clouds. ____ clouds form only at high altitudes.

Explanation:

1. Jet - stream: A narrow air - current in wavelike patterns flowing from west to east around the Earth's hemispheres.
2. Dew - point: The temperature at which water vapor in air condenses to liquid.
3. Wind: Flow of air when heated air rises and cooler air fills the low - pressure area.
4. Pressure - gradient: Difference in pressure between neighboring high and low - pressure areas.
5. Insolation: Rate of heating of Earth's surface by solar radiation.
6. Heat - transfer: Transfer of heat energy without changing temperature between source and object.
7. Weather: Condition of the atmosphere at a given time and place.
8. Heat - content: Heat energy in the air important for weather processes.
9. Thermal - energy: Total energy of molecular motion in a substance.
10. Temperature: Measure of molecular motion on a scientific scale.
11. Air - pressure: Force exerted by the weight of air particles.
12. Mass; volume: Air molecules have mass and take up volume.
13. Barometers: Instruments to measure air pressure.
14. Nitrogen; oxygen: Atmosphere is 78% nitrogen and 21% oxygen.
15. Troposphere; stratosphere: Two main regions of the Earth's atmosphere.
16. Cumulus: Clouds form when warm, moist air rises.
17. Cumulonimbus: Clouds that produce heavy thunderstorms.
18. Cirrus: Clouds that form only at high altitudes.
