What is permafrost?

What is the part of soil that is made from decomposed plant materials?
Humus
Leaching is…
the loss of water-soluble plant nutrients from the soil, due to rain and irrigation. When nutrients in the soil are washed away from too much water.
What is climate?
The weather conditions of an area happening over a long period?
A type of rock that is formed through the cooling and solidification of magma or lava. It is one of the three main rock types.
Igneous rock
A type of rock that is formed from sediment that falls from lakes and ocean and it put under pressure. The sediment is made of dead organisms, tiny rocks, and dead plants.
Sedimentary rock
A type of rock that is formed by heat and pressure under the earth’s surface.
Metamorphic rock
What is the Canadian Shield?
It’s a large area of igneous and metamorphic rocks that form the core of the north American continent.
Calcification is…
the process in dry climates where carrying dissolvable materials moves upward through the soil. At the surface, water evaporates leaving the minerals behind.
The upper area of earth in which plants grow is…
Soil
