Overtime, how might forces within the earth affect the environment on the surface?

Forces within the earth affect the environment on the earth's surface. When magma bursts through the surface of Earth, a volcano is formed. When the volcano erupts, it releases potentially harmful

places of higher salinity. there are parts of the ocean where hardly any rain falls but warm dry winds cause lots of evaporation. this evaporation removes water – when water vapour rises into the atmosphere, it leaves the salt behind, so the salinity of the seawater increases. this causes the seawater to become denser.
