How is the atmosphere heated your answer?
The atmosphere is heated by the Radiation from the Sun, this radiation when passes through the atmosphere is absorbed by soil, plants, water bodies , the air molecules when come into contact with the warmer land and surface of the oceans and lakes increase their energy through conduction causing heating of Earth’s …
How is Earth’s atmosphere heated 7?
Atmosphere of the Earth gets heated up as a result of heat radiated from the Earth’s surface. The water vapour and dust particles present in the air absorb the heat and reflect it back into the atmosphere. Therefore, atmosphere gets heated up more near the plains as compared to the hill stations.
How is atmosphere heated Class 9?
The atmosphere is heated by radiation from the earth below. Therefore, lower layers are warmer than higher layers. There is absence of water vapour and dust particles on high mountains. So there is unchecked radiation.
How is the atmosphere heated Class 9?
Which term best describes how the earth’s atmosphere is heated?
Answer: The sun heats earth’s atmosphere unevenly. this causes convection currents to move in large circles in the atmosphere.
What are the 3 ways that energy is transferred in the atmosphere?
There are three ways heat is transferred into and through the atmosphere:
- radiation.
- conduction.
- convection.
Which layer of the atmosphere is heated by conduction?
the troposphere
Hint: The atmosphere is defined as the envelope of air and other suspended particles that surround the Earth and other planets. The atmosphere of the Earth consists of different layers. Hence, it can be said that the troposphere gets heated up by conduction and the correct answer is option A.
How is atmosphere heated discuss the role of terrestrial radiation in this process?
This process is known as terrestrial radiation. The long wave radiation is absorbed by the atmospheric gases particularly by carbon dioxide and the other green house gases. Thus, the atmosphere is indirectly heated by the earth’s radiation. The atmosphere in turn radiates and transmits heat to the space.
How heat balance is achieved?
The earth-atmosphere energy balance is achieved as the energy received from the Sun balances the energy lost by the Earth back into space. In this way, the Earth maintains a stable average temperature and therefore a stable climate. Shortwave radiation reflected to space by the earth’s surface.
How does heat energy flow into the greenhouse?
The heat loss or gain in a greenhouse occurs in 4 different ways: conduction, convection, radiation and infiltration. Conduction occurs when heat is transferred between two bodies in direct contact. Convection occurs when the heat is transferred via a fluid like water or air to the surface of an object.
What causes the warm air to rise?
As the molecules heat and move faster, they are moving apart. So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward.
What are 2 ways the Earths atmosphere get heated?
(1) Partial absorption of solar radiation by the atmosphere
How does the sun heat the atmosphere?
The sun heats the earth through radiation . Since there is no medium (like the gas in our atmosphere) in space, radiation is the primary way that heat travels in space. Since there is no medium (like the gas in our atmosphere) in space, radiation is the primary way that heat travels in space. When the heat reaches the earth it warms the molecules of the atmosphere, and they warm other molecules and so on.
What is trapping the heat inside the atmosphere?
Greenhouse Effect, is the trapping of heat emitted from earth’s surface by certain gases (water vapor, carbon dioxide, methane, ozone, and nitrous oxide) in the atmosphere, thereby insulating and warming the planet without which the earth’s climate will be very cold.
How does heat move through and affect the atmosphere?
Heat radiates from the ground into the lower atmosphere. In conduction , heat moves from areas of more heat to areas of less heat by direct contact. Warmer molecules vibrate rapidly and collide with other nearby molecules, transferring their energy.
