WEATHERING
Does weathering change the earth's surface?
Yes
Does temperature affect how fast something weathers?
Yes
Small holes in the soil are called
Pores
Material that has never been alive
Inorganic
What are the three types of rocks
Igneous, Sedimentary, Metamorphic
What is Oxidation?
Oxygen combining with other elements or molecules
What is one cause of chemical weathering? (there is more than one)
Acid rain
Carbon dioxide
What is Organic Matter?
The remains of something that was once alive
The shape and steepness of the land
Topography
These rocks are made by magma or Lava and called "Fire Rocks"
Igneous
What are two causes of mechanical weathering? Mechanical is the Natural things that happen (there are more than two)
Trees / Plants
Ice
Abrasion
Animals
Increased surface area means weather has a (bigger / smaller) effect on breaking things down.
Bigger
Can all plaints grow in all types of soil? (Can I plant a tree anywhere?
No
Process of changing once living material into organic matter
Decomposition
These rocks are made by compression and cementation (smooshed together)
Sedimentary
How are trees good and bad for weathering?
They break apart things but also help with erosion, especially on hills
Physical process that naturally breaks rock into smaller pieces (hint - it's one of the weathering)
Mechanical Weathering
Layers of soil formed by weathering is called
Horizons
The starting material of soil is called
Parent material
These rocks are made by heat and pressure and are deep in the earth
Metamorphic
What are the two types of weathering?
Mechanical and Chemical
This process changes rock into new material (hint - it's one of the weathering)
Chemical Weathering
Which soil did our plants not sprout in?
answers vary
All the organisms that live in a region are called a
Biota
Draw the rock cycle with the 4 major parts
Igneous - sediment - Sedimentary - Metamorphic
