GROUNDWATER:water stored beneath the surface of the Earth.
Wells can be built to extract groundwater from aquifers for use by human beings as a source of drinking water.
Ground water accumulates from rainwater. The water penetrates the Earth through porous sand and rock until it is stopped by a layer of impermeable material,exhale:clay
Groundwater can escape from the Earth springs. These occur where the impermeable ayer is cracked or mixed with permeable rock.
Upper level groundwater forms the water table.
The rain water accumulates in areas of permeable rock,sand or gravel known as aquifers
GLACIERS:large masas of slow-moving ice
Glaciares move downhill very slowly.This´s because their immense weight and the force of gravity.U-shaped valleys were formed by glaciers in parts that once were covered in ice. They can only exist in areas where temperature is always or nearly always below 0º. As they move glaciers transport morasen. This rock debris can be seen in sheets and piles where glaciar has passed or in the surface of the ice.
ICEBERG:floating pieces of glaciar that have reached the sea and broken-off
