What are the 3 main causes of uneven warming of the earth?
Unequal heating of Earth, atmospheric convection currents, rotation of the earth, Coriolis effect, earth’s orbit on a tilted axis, and the circulation of ocean waters at the surface and deep ocean. What happens to the air pressure as you move from the troposphere to the exosphere?
What is the effect of unequal heating of the earth?
Unequal heating of the earth’s surface causes temperature differences which cause pressure differences. Lower temperatures (heavy air) cause higher air pressure. Wind direction is described as where the wind is coming from. For example a northerly wind blows from the north to the south.
What is meant by uneven heating and why does Earth experience uneven heating?
The answer is due to uneven heating of the Earth by the sun. When the earth orbits the sun, the center of the Earth gets more direct sunlight than the poles. This is exacerbated by the Earth’s tilt. Since the center of the Earth gets more sunlight, it is consistently hotter than other parts of the Earth.
Which is most responsible for the uneven heating of the atmosphere?
The movement of air through Earth’s — or any planet’s — atmosphere is called wind, and the main cause of Earth’s winds is uneven heating by the sun. This uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.
How does uneven heating of the earth cause wind?
Wind is the movement of air caused by the uneven heating of the Earth by the sun. Warm equatorial air rises higher into the atmosphere and migrates toward the poles. This is a low-pressure system. At the same time, cooler, denser air moves over Earth’s surface toward the Equator to replace the heated air.
How is heat transferred to Earth?
Energy is transferred between the Earth’s surface and the atmosphere in a variety of ways, including radiation, conduction, and convection. Conduction is one of the three main ways that heat energy moves from place to place. The other two ways heat moves around are radiation and convection.
What causes temperature change?
Many factors, both natural and human, can cause changes in Earth’s energy balance, including: Variations in the sun’s energy reaching Earth. Changes in the reflectivity of Earth’s atmosphere and surface. Changes in the greenhouse effect, which affects the amount of heat retained by Earth’s atmosphere.
What affects the jet stream position?
The earth’s rotation is responsible for the jet stream as well. The motion of the air is not directly north and south but is affected by the momentum the air has as it moves away from the equator. The reason has to do with momentum and how fast a location on or above the Earth moves relative to the Earth’s axis.
How does the atmosphere respond to uneven solar heating?
How does atmosphere respond to uneven solar heating? The uneven heating causes temperature differences, which in turn cause air currents (wind) to develop, which then move heat from where there is more heat (higher temperatures) to where there is less heat (lower temperatures).
How do seasons affect the heating of the atmosphere?
The Seasons (Northern Hemisphere) During the summer, the Northern Hemisphere will tilt towards the Sun resulting in more direct sun radiation and higher temperatures. In the winter, the weaker sun radiation will have a struggle drying out the lower part of the atmosphere.
What is the effect of heating up of the land near the Earth equator?
In summer, near the equator the land warms up faster and most of the time the temperature of the land is higher than that of water in the oceans. The air over the land gets heated and rises. This causes the winds to flow from the oceans towards the land.
What causes air to move?
Air moves due to a difference of air pressure which can be caused by different temperatures. Air pressure is the push caused by the particles in the air. Air pressure causes weather patterns, such as storms. Air naturally wants to move to lower areas of pressure.
How does heat from the sun get to Earth?
Heat moves in three ways: Radiation, conduction, and convection. Radiation happens when heat moves as energy waves, called infrared waves, directly from its source to something else. This is how the heat from the Sun gets to Earth. The light from them radiates to us.
What is one effect of the uneven heating of Earth caused by the sun?
Solar heating of the Earth’s surface is uneven because land heats faster than water, and this causes air to warm, expand and rise over land while it cools and sinks over the cooler water surfaces.
