What is the primary reason why the surface of Venus today is some 450C hotter than the surface of Earth?
A combination of things. First, Venus is much closer to the sun than earth, so its surface receives more radiant energy from the sun. Add to that the fact that Venus is surrounded by a thick layer of carbon dioxide clouds, which create a runaway greenhouse effect. Bottom line: Venus's surface is about 800 degrees hotter than earth's surface.
Is it true that the hotter a surface is the more heat it radiates?
yes
What is lithosphere movement?
The lithosphere is the solid part of the Earth's surface, the crust and uppermost mantle, which is fragmented into plates which "float" over the hotter, more fluid asthenosphere.
How many times hotter is Venus than Earth?
Venus is over 800 degrees Fahrenheit. Hot enough to melt a lead brick. The hottest temperature recorded on Earth is 136 degrees Fahrenheit in the Sahara Desert. In a nutshell it is A LOT hotter.
Why is there a mass luminosity relation?
If you think about it, it makes sense. Stars with more mass will be hotter in the center, because the center will be under more pressure. A hotter center means that nuclear reactions will proceed more quickly, and thus produce more radiation. This radiation eventually works its way to the surface of the star, so the surface of a more-massive star will be hotter. Hotter surfaces radiate more energy, and thus appear brighter. Of course, there are other variables, such as chemical composition, involved, so the mass-luminosity relation is only approximate. And other physical considerations make some stars variable, sometimes over a large range in luminosity. There are also special cases, such as white dwarfs, for which there is an entirely different relationship between mass and luminosity than that which holds for "normal" stars.
What has more pressure the center or surface of the earth?
The center, because that is where all the gravity of Earth pulls you down(this is why when you jump you come down) create lots of friction and pressure

On the earth's surface what circle's center is the earth's center?
Every so-called "great circle" is (more or less) the longest circumference of the Earth that includes any two points. The great circle includes the shortest distance between the two points for travel along the Earth's surface.

Why is Jupiter's central core temperature so much hotter than earth's.?
Jupiter's central core is much hotter than earth because the mass compresses more the more mass compress and the more mass a planet has, the hotter it is.

Where do you experience more gravity on earths surface or earths center?
on the surfaceNote:Since the earth's composition is not homogeneous, the gravitational acceleration onthe surface is probably less than what it is some small distance below the surface,but it's certainly greater than at the center.
What happens to rocks that are pushed under earth's surface and become hotter and experience more pressure?
They become exposed to deformation in a process called metamorphism, and become metamorphic rocks.
Magma tends to rise toward Earth's surface principally because?
Magma tends to rise towards Earth's surface primarily because rocks become less dense when they melt. The hotter the magma, the more the rocks are likely to "float," if you will.
