How do different surfaces on Earth warm and cool?
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. This differential heating is passed on to the air above by conduction which causes air expansion and changes in pressure.
Why are some places on earth cold while other places are warm?
Temperature differences are accompanied by density differences; cold air masses are denser and thus heavier than warmer ones. Cold air sinks and warm air rises. These densitydifferences and resulting air motions are generated by differences in the atmospheric pressure at different locations.
Why are all places on the Earth not equally cold?
The axis of the earth is tilted at 23.5° angle towards the sun. So, the different portions of the earth recieves different amounts of solar radiation or heat energy.
When the Earth’s surface becomes warm How does it cool down?
The sun has warmed the surface during the day. Once the sun goes down, the earth’s surface will begin to cool (energy emitted is greater than energy received). This causes the earth’s surface to become progressively cooler during the night.
How does the Earth surface remain warm?
Earth’s atmosphere keeps much of the Sun’s energy from escaping into space. This process, called the greenhouse effect, keeps the planet warm enough for life to exist. Greenhouse gases in the atmosphere also absorb and hold some of the heat energy radiating back from Earth’s surface.
When the Earth’s surface is heated takes place?
The surface of the Earth is heated by incoming shortwave radiation from the sun. This radiation heats the Earth which in turn releases long wave radiation which warms the atmosphere and is what is reflected by the Greenhouse effect.
Why is it so hot at the equator?
Why is it hot at the Equator and cold at the poles? Due to the tilt of the Earth, the Equator is closer to the sun so receives more of its energy. The Equator has a smaller surface area so heats up quickly compared to the poles. This means more heat from the sun makes it to the surface of the Earth.
Which place on the earth are equally hot throughout the year?
Our Earth receives all its heat mostly from the Sun.
Why are all the places on the earth not equally hot Class 5?
That part of the Earth which get direct sunlight are comparatively hotter than the which get sunlight once in a while , thus we can say that all place of the earth will not equally hot.
How does the Earth cool down?
Clouds can block light and heat from the Sun, making Earth’s temperature cooler. You’ve probably noticed this kind of cooldown on a cloudy day. However, some heat from the Sun does get down to Earth. Clouds can trap that heat from the Sun.
How heat is transferred in the Earth’s interior?
Heat is transferred to the surface of the Earth from the hot Earth’s core by conduction and from radiation from the Sun. The remaining heat on the surface is sent out into space in the form of infrared radiation.
