How do convection currents work in the mantle?
What forces would lead to the movement of the plates over the surface of the earth? At this time it is believed this movement results from mantle convection. Deep within the earth there is a large amount of heat coming from two sources: the magma remnants of the Great Bombardment, and radiation from radioactive elements. This heat, in accordance with the 2 ndlaw of thermodynamics, must flow to a cooler place, and subsequently rises to the surface of the Earth. If the Earth were smaller, this heat would flow by conduction, but because of the relatively large size of the Earth, convection also takes place. Thus, as in heating a pot of water on a stove, convection currents are established within the earth, which bring warm material to the surface and send cooler material to the interior.

How do mountains create their own local winds?
Mountains can not create a wind. Winds are the result of the heat coming from the Sun and the heat radiated by the Earth into space. They are the atmospheres response to the differential of heat within the atmosphere. All mountains do is modify the the flow of the wind as they act as barriers to this flow.
Does the surface north or south of the equator receive less heat because Earth's surface is curved?
== == The fact that the surface of Earth is curved definitely has a bearing on how much heat any particular point on Earth's surface receives at any given time. But remember, the axis of Earth is tilted about 23 degrees from perpendicular. As such, the critical point is not always on the equator. The critical point could be anywhere between the Tropic of Cancer and the Tropic of Capricorn, depending on the time of year and the time of day. Every moment of every day, there is a point on Earth, somewhere between the Tropic of Cancer and the Tropic of Capricorn, where for a brief second the sun is directly overhead, 90 degrees from the surface of Earth. That point gets the maximum benefit from the sun's rays for that brief second. The more direct the 'hit' of a ray is to the surface of Earth, means the more of the heat of the ray that gets to the surface of Earth. When a ray needs to penetrate through the atmosphere (and all the other 'ospheres) on an angle, it loses heat. The more the angle is away from 90 degrees to the sun, the more heat is lost. This is often quite noticeable during the course of the day. The morning may begin cool, then it will heat up during the day, and cool off again in the evening. This is all related to the angle at which the sun's rays hit Earth. The tilt of Earth is also the reason for the seasons. The less sunlight that reaches the surface of Earth, the less heat also reaches the surface of Earth. During winter, there are fewer hours of sunlight than in summer, and the angle at which the sun's rays reach Earth is farther away from 90 degrees than in summer.
What is the distance from earth's surface to the end of earths atmosphere?
The Earth's atmosphere extends anywhere from 250-400 miles off the surface, depending on where you are standing. Near the equator, it is thicker due to the heat from the surface and cloud reflection, and the high moisture and humidity.
At which time of day is the heat flow entering Earth's atmosphere Hin highest?
At which time of day is the heat flow entering Earth's atmosphere (Hin) highest?A. sunriseB. middayC. sunsetD. midnightThe answer is B midday
What is the heat from below earth's surface called?
Heat from inside the Earth is called geothermal heat.
What affects the distribution of heat received by the Earth's surface?
The formalism of Huestis for placing bounds on subsurface temperatures is generalized to the case of heat flow measurements on a surface which is neither flat nor isothermal. The strip extending between the surface and the depth of interest is imbedded in a larger flat strip extending to a horizontal level everywhere above the topography. Using linear programming, heat sources within and temperatures on the boundary of this simpler region are found such that the heat flow data and temperatures on the Earth's surface are fit, heat production constraints are met, and the extremal bound is achieved.
When the heat beneath the surface of Earth melts the plate material and sends molten rock to the surface what occurs?
A volcanic eruption, or just a simple lava flow, depending on the magnitude.

Why Earth's interior is warmer than its surface?
Earth's surface is free to radiate heat into space. The interior is not. The interior does transfer heat the the surface, but rather slowly. It is hot due to residual heat from Earth's formation and from the heat generated by the decay of radioactive elements.
What surface heat faster then water surface on earth?
water!
What is the Solid layer of earth that can flow because of great heat and pressure?
The mantle is the solid layer of earth that can flow because of great heat and pressure
Which layer of the Earth is heat escaping at Earth's surface?
lithosphere
What does the heat from the Earth's core do?
It attempts to reach the surface of the Earth.
What causes earth's surface to heat?
The sun ray's are most responsible for Earth's surface temperature.
What heat warms the surface of the earth?
the sun
