Six months later, the southern hemisphere is receiving more direct sunlight and is warmer. Most of your body mass is water. Describe the creation of the hydrogen and oxygen atoms that make up the water. The planetesimals gained their kinetic energy from gravitational potential energy. Give one example of its occurrence on Earth.
Convection is the process of hot materials rising and cool materials descending.
It occurs in Earth's troposphere, where it helps get rid of heat trapped by the greenhouse effect. Convection also happens in Earth's mantle. Turn it off and you reduce plate tectonics. Convection also happens the the core, where it helps form the magnetic field. The semimajor axis of Jupiter's orbit is 780 million km.
