Triggered by the movement of the earth’s plate | earthquake |
Gravity or rain or both pulls rocks and mud down the mountain causing destruction | landslides |
The wearing a way of sediments by water, waves, wind or ice | weathering |
when thick magma and large amounts of gas build up under the surface | volcanoes |
The moving or carrying a way of sediments to a new location | erosion |
An earthquake in the ocean causes these giant destructive waves | tsunami |
Earthquake, landslide, hurricane, tsunami and volcano | rapid changes to the Earth's surface |
The dropping of sediments to a new location | deposition |
Weathering, erosion and deposition | slow changes to the Earth's surface |
Very small in size, tiny, a speck, crumb | particles |
A huge V-shaped valley made from moving water | canyon |
A huge moving body of ice that scrapes the landscape | glacier |
A mound of sand deposited by wind | sand dune |
large flat area of land at the mouth of a river | delta |
An area of land, or a land shape found on the surface of the Earth | landform |
Tiny particles of broken down rock, about the size of salt, very little water stays, loses water, no nutrients | sand |
Finer and softer sand, like flour, silky smooth, slippery when wet, some water stays, some nutrients but erodes easily | silt |
A sticky when wet, fine grained soil that does not allow water to flow through easily, hold to much water, needs nutrients, compacts when dried | clay |
Dark and chunky soil full of organic matter and plants, sticks and leaves | humus |
The best soil of all because it’s a mixture of humus, clay and sand | loam |
Smaller stones, pebbles of rock, no water stays, no nutrients | gravel |
