Soil
The layer of dark fertile soil, made of rotting plants and lies at the surface.
What is Top Soil?
Igneous rocks are formed when this material from volcanoes cools and solidifies.
What is magma?
Eroded rocks (sediments) are transported by these landforms, where they are compacted together into layers to create sedimentary rocks.
What are streams and rivers?
Metamorphic rocks are formed from these two processes.
What are heat and pressure?
This process is the breakdown of rocks by precipitation, temperature and biological activity.
What is weathering?
Underneath the surface, this layer of soil contains plant roots, rotting plant and animal remains.
What is Sub Soil?
This type of igneous rock has a foam like appearance from rapid cooling and depressurizing causing bubbles.
What is Pumice
This sedimentary rock makes up about 10% of all sedimentary rocks on the planet. It is common in architecture, especially in European castles.
What is limestone?
This type of metamorphic rock was used by the ancient Greeks and Romans in their buildings and artworks and is used today for flooring, clocks, tables and statues.
What is marble?
What is acid rain?
This type of soil is most coveted by gardeners, it is the perfect blend of clay, sand and silt. It holds water and nutrients well.
What is loam?
The Canadian Shield found outside of our classroom is composed of many rocks including this common igneous rock that starts with G.
What is granite?
This sedimentary rock is soft, white and porous.
What is chalk?
This type of metamorphic rocks is made up of clay and or volcanic ash, which gives it it's black colour.
What is slate?
The process of moving weathered material from rocks is called this.
What is erosion?
This type of soil is generally found in bogs or marshlands.
What is peat?
The most common igneous rock on the planet is this rock that starts with a B. It is found in concrete.
What is basalt?
This black or brown sedimentary rock usually occurs in layers or veins and is composed primarily of carbon.
What is coal?
Granite, when exposed to heat and pressure, becomes this metamorphic rock.
What is gneiss?
Erosion can happen from wind, liquid water and this material.
What is ice.
The three most common and most important minerals in soil are potassium, nitrogen and this element.
What is nitrogen?
Intrusive igneous rocks cool slowly underground allowing to form these, often beautiful structures.
What are crystals?
This sedimentary rock is made from particles of other rocks and is often used in carving.
What is sandstone?
Metamorphic rocks are often hard, hardness is measured on this scale.
What is mohs scale?
This process is characterized by rock particles being moved to a new location where particles form new landforms, which can eventually become layers and rock.
What is deposition.
