Tsunami

Earthquakes form/due to tectonic plates shifting under the earths crust

The shaking movement the earthquake forms comes from in the earths crust at the center point.

earthquakes are very dangerous and cause loads of deaths annually

a Tsunami is essentially a big wave that starts from and underwater earthquake.

Farming

farmers need to provide heat, water, food, welfare, crops and animals to have a big farm.

farmers tend to grow crops in a garden section on their farm, when the crops are ready, the harvest the and sell them at the farmers market.

Rocks

types of rocks

igneous

Sedimentary

Metamorphic

Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.

Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place.

Igneous rock, or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust.
