What is albedo of the earth?
The fraction of the incoming solar energy scattered by Earth back to space is referred to as the planetary albedo. This reflected energy is a fundamental component of the Earth’s energy balance, and the processes that govern its magnitude, distribution, and variability shape Earth’s climate and climate change.
What is heat balance of the earth?
Earth’s heat balance is and extremely important factor in what makes the Earth livable. The fact that the Earth can respond to slight changes in the amount of incoming radiation to maintain a fairly stable temperature is a result of Earth’s energy budget.
How does the earth redistribute heat?
Solar power drives Earth’s climate. Energy from the Sun heats the surface, warms the atmosphere, and powers the ocean currents. The climate’s heat engine must not only redistribute solar heat from the equator toward the poles, but also from the Earth’s surface and lower atmosphere back to space.
Why do you feel warm when you are near a fire source?
Answer: You feel hot because, when you stand near a fire the temperature around you is greater than your body temperature leading to an exchange of heat, your body then gain heat from the fire i.e an endothermic reaction occurs and the heat absorbs leads to an increase in your body temperature making you to feel hot.!
Is the latest important mode of heat transport in the Earth?
Radiation is the least important mode of heat transport in the Earth. The process of heat exchange between the Sun and the Earth, through radiation, controls the temperatures at the Earth’s surface. Inside the Earth, radiation is significant only in the hottest parts of the core and the lower mantle.
What heats build up underneath the crust?
- Answer:
- SUBDUCTION.
- Explanation:
What heat moves through radiation?
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. In fact, all hot things radiate heat to cooler things. When the heat waves hits the cooler thing, they make the molecules of the cooler object speed up.
What are the cheapest mode of transport?
Railways
