Answer:
Convention currents are found in the asthenosphere part present in the mantle of the Earth.
Explanation:
The Mantle is the middle layer of the earth surface extending up to 2900 kilometers.
Beneath the Mantle lies the core which contains molten rocks and materials called magma.
The materials are highly radioactive and immensely heated. These highly hot condition creates pressure on the middle layer (Mantle).
As a result, large convention currents are generated excessively
Answer:
ozone. CFCs drift slowly upward to the stratosphere, where they are broken up by ultraviolet radiation, releasing chlorine atoms, which are able to destroy ozone molecules.
Condensation is conversion of vapours to liquid
in vapour the molecules of water are far from each other and can move here and there. When a liquid like water condense the molecules come closer to each other.
Thus come closer together and stick to each other.
