1. the density of gas particles in a section of earth's atmosphere decreases. which of the following is the most likely explanation for this event?

the air pressure in that section of earth's atmosphere decreased.

the air pressure in that section of earth's atmosphere increased.

the total number of gas particles in earth's atmosphere decreased.

the total number of gas particles in earth's atmosphere increased.

2. which of the following correctly describes a way in which earth's atmosphere interacts with the geosphere?

it contains gases that living organisms breathe.

it contains gases that trap incoming solar radiation.

it provides a medium for cycles that provide nutrients to living organisms.

it provides a medium for water to move between earth's surface and the air.

3. which of the following is considered a benefit to using wind energy as a source of power?

winds blow consistently.

wind energy does not pollute.

wind turbines require very little land to construct.

winds produce higher quality energy than other sources.

4. as a barometer lowers, what kind of weather can be expected?

there will likely be no change in the weather.

the weather will likely become clearer and drier.

the weather will likely become cloudier and stormier.

the weather will likely become cooler and less humid.

5. which of the following do meteorologists not typically use weather balloons to record?

atmospheric pressure

cloud types

humidity

temperature

6. during which step in the can crush lab did the air pressure outside the can become greater than the pressure inside the can?

the can was filled nearly to the top with water.

the can was placed on the hot stove burner for several minutes.

the can was removed from the hot oven burner.

the can was placed upside-down in the water-filled pan.

7. water molecules evaporate from a lake near the equator and rise into the atmosphere, as shown in the diagram below. as the molecules travel away from the equator, which step in the water cycle is most likely to happen next?

diagram of a globe showing a water molecule moving north away from the equator. (see picture).

the molecules cool and eventually form clouds.

the molecules freeze and eventually form ice crystals.

the molecules heat up and eventually form water vapor.

the molecules break apart and eventually form precipitation.

8. as an airplane rises through the atmosphere, machines cause the pressure inside the cabin to decrease. as the airplane descends toward earth, machines cause the pressure inside the cabin to increase. based on your observations from the can crush lab, explain why these changes in pressure are necessary.

9. where on earth's surface might you be if you are experiencing the trade winds? explain how air pressure, temperature, and the coriolis effect influence the movement and direction of these winds.

The reason that explains that he density of gas particles in a section of Earth's atmosphere decreases is that the air pressure in that section of Earth's atmosphere decreased. You should keep in mind that the density can vary because the molecules of gas are free to move. The main point that led to the correct answer to this question is the fact that atmospheric density decreases as the altitude increases.

The statement which correctly describes the way in which Earth's atmosphere interacts with the geosphere is: it provides a medium for cycles that provide nutrients to living organisms. The interaction between these parts of Earth's life is an essential part of everything living on the Earth as it is responsible for physical balance of the main life components.

The fact that wind energy does not pollute is considered a benefit to using wind energy as a source of power. Pollution seems to be one of the major problems of the Earth's state in its general sense, therefore it is a nice opportunity to keep up our planet in good condition because wind energy brings absolutely no harm to the environment.

As a barometer lowers, the kind of weather that can be expected is: The weather will likely become clearer and drier. Barometer is an special instrument that is used to measure atmospheric pressure and if it's indicator is placed low it is a good sign, but if it has high position the weather most likely to be cloudy or worse.

Meteorologists do not typically use weather balloons to record cloud types.These balloons are primarily used in order to measure or collect data that is connected to atmospheric pressure, temperature, humidity, wind speed and frequency.

During the step when the can was placed upside-down in the water-filled pan the air pressure outside the can become greater than the pressure inside the can. If an object participating in an experiment changes its position, outside air pressure will always be greater than the pressure inside the the object because of reaction of atmospheric pressure.

As the molecules travel away from the equator, the molecules cool and eventually form clouds. The closer they are placed to the equator the warmer the temperature is and molecules heat up. So, as they leave the closest zone of the equator, they cool.

The represented changes in pressure are necessary because it is a question of safety. These changes prevent the bad effects regarding people's boies, making people in cabins be able to breathe without having heads explode, or having them weak.

The place on the Earth's surface where you might be if you are experiencing the trade wind is tropical to sub-tropical latitudes on either side of the equator. The areas of low pressure areas usually move air counterclockwise, spinning clockwise and in across the southern hemisphere. What about areas where high pressure prevails, they spin clockwise and out in the northern hemisphere, while counter-clockwise and out in the southern hemisphere. Remember that the high pressure areas do not affect the trade winds at all because in tropics the pressure is low.
