Why is soil Important?
Give me one reason.
The soil helps to clean our water acting as a filter.
Plant also need soil to grow by getting nutrients.
Soil releases gases such as carbon dioxide into the air.
______________ is the process that breaks down rocks into smaller pieces which is caused by wind, rain, ice, chemicals, freezing, or thawing.
Weathering
People who study rocks and minerals classify rocks according to the way they are formed. What are these Scientists called?
Geologists
Pumice
Basalt
Granite
Quartz
Igneous
If a rock Weathers and Erodes it turns into ______________.
Sediments or Sedimentary Rock.
What is the Hardest Mineral on Earth?
Diamond
Smooth to the touch
When you roll it between your fingers, dirt is left on your skin.
Retains water longer
Fairly fertile
Cold and drains poorly
Silt
__________ is the movement of rock pieces from place to place which is caused by wind, rain, waves, gravity, or moving ice.
Erosion
_____________ rocks are formed by great heat or pressure.
Metamorphic
Limestone
Coal
Shale
Sedimentary Rocks
If a rock get Heat or Pressure added to it then it will become ____________ Rock.
Metamorphic Rock.
What 2 Minerals can Calcite Scratch?
Talc and Gypsum
Smallest particles found in soil
Good water storage
Sticky when wet, smooth when dry
Rich in plant food for better growth
In the summer, it could turn hard and compact
Clay
___________is when the particles carried by water, ice, or wind by the forces of erosion are deposited (dropped) in another location. Basically, when material is added to a landform, we call it deposition
Deposition
__________ rocks form when melted rock cools and hardens
Igneous
Rocks are always changing and the process of change is called the ______________. The changes happen very slowly (millions of years) which makes it difficult to see.
Rock Cycle
When you melt Igneous Rock or Metamorphic rock it will turn into __________.
Magma
Gold, silver and copper are examples of minerals that have ______________________ luster.
Metallic
The largest particle found in soil
When you rub it, it feels rough and gritty.
Does not contain many nutrients
Good for providing drainage
Sand
This layer is made up of minerals and decomposed organic matter. It is fairly thin (5-10 in. thick). This is the primary layer where plants and organisms live.
Topsoil
_______________ rocks are formed by many years of sediment (many pieces of rock and soil) squeezed together until they harden. (compacted and cemented)
Sedimentary Rock
You will find the _________rocks and at the top and at the bottom you will see the _________ rocks!
Top: Youngest Bottom: Oldest
I am a rock that had been weathered or eroded. Then heat and pressure got added to me . What am I now?
Metamorphic Rock.
