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.

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.
== == 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.
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?A. sunriseB. middayC. sunsetD. midnightThe answer is B midday
Heat flow entering the Earth's atmosphere varies throughout the day, but typically the highest levels occur during the afternoon when the sun is overhead, resulting in peak heating. At night, heat flow decreases as the Earth cools.
The two sources of energy that heat Earth's surface are solar radiation from the sun and geothermal energy from within the Earth's core. Solar radiation is the primary source of energy that warms the surface, while geothermal energy contributes to heat flow from the Earth's interior.
This is because the earth absorbs the incoming radiation and although the sun is at its highest, the surface is still being heated and is releasing that heat which ultimately creates a warmer environment a few hours after the sun is at its highest point
Heat flow within the Earth's interior is driven by the heat from the Earth's core and mantle. Molten rock, or magma, moves through the Earth's interior in a process called convection. This movement is responsible for creating volcanic activity and shaping the Earth's surface through processes like plate tectonics.
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.

the earth's hot materials move towards the earth's surface because the crust is weak and there is no other way in which the hot materials can escape except explosion. there is no other place to where it can magically teleport so to escape so thus, it explodes out mostly through the weak cracks and fissures on the earth's surface. -Zulekha Das
The heat from below Earth's surface is called geothermal energy. This energy originates from the natural decay of radioactive isotopes in the Earth's crust and mantle, creating heat that can be harnessed for various applications such as electricity generation and heating.
The rate of geothermal heat flow is generally greatest in regions with high levels of tectonic activity, such as along the boundaries of tectonic plates or in volcanic regions. This is because the movement of the Earth's crust in these areas facilitates the transfer of heat from the Earth's interior to the 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.
