<span>The earth has four layers; the
crust, the mantle, the outer core and the inner core. The Earth’s magnetic
field is the combination from the convection it receives from the outer core
and the Coriolis Effect. The answer <u>is letter A.</u> The outer core is
composed mostly of liquid nickel and iron. It is expected to have that state of
metal because it has a higher temperature. The inner core cannot hold much of
the magnetic field because of its high temperature and high pressure that
exceeds the outer core. The temperature decreases however as the layer goes
outwards. </span>

People can fly planes into the air and release chemicals into the air if they really need the rain and sometimes a storm will form. Increase in pollution can because all the gas and chemicals that come off the pollution will go into the ozone layer and cause an increase in moisture which could cause rain clouds to form. One last thing is evaporation, condensation, and precipitation. Plants absorb water and moisture then it would evaporate into the air which would form rain clouds, then the rain clouds would have rain in them and then rain would fall out of the clouds.
