Friction
from the bottom of the earth
The heat driving convection currents in the asthenosphere primarily comes from the Earth's internal heat. This heat is generated through the radioactive decay of elements in the Earth's mantle and core. The flow of this heat causes the asthenosphere to partially melt and create convection currents that drive the movement of tectonic plates.
The heat in the asthenosphere primarily comes from the heat generated by the decay of radioactive isotopes in the mantle and the residual heat from Earth's formation. This heat causes the material in the asthenosphere to become less dense and rise, generating convection currents.
Gravity
the mass of the earth exerts gravity on all objects around it
Neither, it is radiation that causes you to feel the heat from a distance.
Its a process for hot air rising, and cold air sinking hope this helps!:) Actually, it doesn't have to be air. Convection occurs in most liquids and gases. Magma beneath the Earth's crust is the best example of natural convection that I can come up with.
The effect of the moon is werewolfs come out and howl
The sun gets closer to the earth and causes the earth to a perfect climate for plants and animals to procreate.
i love this question. i may only be a 7th grader but i learned about them this year. revolution is when the earth is orbiting the sun and this takes a full year to do. and rotation is when the earth is rotating on its axis which takes 24 hours to do and this causes weather. it also causes the Coriolis effect which causes wind to move in a curved path. that's where cold and warm fronts come from.
Convection is the primary mechanism for air movement in the atmosphere, where heat from the Earth's surface causes air to rise and cooler air to sink. Conduction plays a minor role in air movement by transferring heat from one air parcel to another when they come into contact with each other. Both processes contribute to the overall circulation patterns in the atmosphere.
