Want this question answered?
the forces of gravity pull the crumbs towards the earths core but in space the gravity is less so the pull force is not as great as the earths pull
after the ground is weakened after a storm or water source the ground start to fall that will start a earthflow
percipitation
Precipitation.
Rain? Really? Of course its Rain, its called Precipitation!
By Precipitation like rain and snow fall. Wnen the sun evaporates water from the sea then the minerals mixed with the water left behind in the sea and only the fresh water go up as gas. And then fall as fresh water(rain). then it goes under the ground. while going underground the soil and rock filters it. so earth's fresh water comes from ground water. "I Guess"
The local fresh water fall
Tides
Runoff
No when there density increases
The reason there is a concern about the availability of fresh drinking water and rightly so, is perhaps because for one thing the water covering the planet is salted and extracting the salt from the water is a costly exercise. Also you should understand that fresh water is not tap water as that water is deadly and polluted. Also the lack f rain fall in some areas will reduce the availability of fresh water, comes from the hills and mountains and flows underground. It is almost impossible to capture this water in its' natural state, which leads me to believe that even bottle water is not fresh water. You can only get FRESH water at the point where it comes out of the ground.
Gravity.
the forces of gravity pull the crumbs towards the earths core but in space the gravity is less so the pull force is not as great as the earths pull
because of the earths gravity, everything exept for helium filled balloons falls to the ground
The main sources of fresh water on land are snow and rain which fall as precipitation.
Water vapor is important because it creates clouds and it's water molecules combine to form water droplets that can either fall to the ground as rain, or freeze and fall to the ground as sleet, snow, or hail.
after the ground is weakened after a storm or water source the ground start to fall that will start a earthflow
