Soil science is the science dealing with soils as a natural resource. It includes soil formation, soil classification, and properties of soils. Soils are important to our lives. Soils are needed to grow most of our food. Soils support our buildings. Soils also store water and nutrients. Soils determine where plants grow and where animals and people live.

Rocks rubbing against each other

Glaciers are huge masses of ice that rest on the land. A glacier forms when a large amount of snow piles up, pressing the snowflakes together and eventually forming ice. The process of forming a glacier happens over many years- sometimes over centuries. Glaciers move by gravity, the steepness of the Earth’s surface, and the pressure from the large amounts of ice that collects. The climate sometimes causes glaciers to melt, or retreat. As glaciers move they cause changes to the Earth’s surface. The four pictures below show a mountain valley before glacier formation, during glacier formation, and after glacier melting, or retreat.
a)
1, 2, 3, 4
b)
4, 3, 2, 1
c)
2, 1, 4, 3
d)
3, 4, 1, 2
