The sun... and the earth's mantle. The surface of the earth is mainly warmed by radiation from the sun - but we also get some heat through the ground - from the molten mantle underneath the Earth' crust.
The gravitational pull keeps the Earth's atmosphere close to the surface...
Gravity
The Earth has an active interior that keeps it in a state of perpetual change. In other words, below the solid crust on which we live, is molten or semi-molten rock (magma). Our continents are like rafts, floating on molten rock, and imperceptively constantly on the move. On the surface, erosion and depositing is constantly happening. Therefore, an active planet is one were changes is constantly going on.
Source of heat energy that keeps the surface of the Earth warm enough support LIFE
The Earth's gravity keeps our feet firmly on the ground.
The force that keeps us on Earth is called gravity. It is the force of attraction between objects with mass, such as the Earth and everything on its surface.
Yes.
Weight.
Being in the liquid form water keeps on moving on the surface and into the earth due to gravitation force of the Earth.
