Soil
What are the three soil particles?
Clay, Sand, Slit
Root Pry is a type of what kind of weather?
Mechanical
What is a Glacier?
large mass of ice that moves over land
What percent of earth's water is found in oceans?
97%
Where is the majority of the water on earth located?
Oceans
Where do we find the most organic material?
Horizon O or A
Give an example of chemical weathering
Oxidation, Plant Acids, Carbonation, Hydration
The movement of a glacier will ________ the land beneath it
erode/gouge
Which elements are the most abundant in oceans? (Besides hydrogen & oxygen)
Sodium & Chlorine (NaCl- Salt)
This is when water vaopr turns back into a liquid and forms clouds
Condensation
What are the layers of a soil profile called?
Horizons
Natural break down of rocks & minerals is called
Weathering
The type of glacier that is long & narrow, forms when snow & ice build up high in a mouation valley
Valley Glacier
What is salinity?
How much salt is dissolved
This is when the sun heats up the water on earth surfaces and turns to vapor
Evaporation
What is the composition of soil (pie chart)?
45%- Soil Particles, 5% Humus, 25% Air, 25% Water
This is the type of weather that changes the compostion of the rock as it break it down into small parts
Chemcial
Type of glacier that covers much of a continent or large island
Contenental
What is the relationship between density & temperature?
As temp increases, the density decreases, if the temp decreses than denisty increases
Precipation
What are the 6 factors that affect soil formation?
Parent Matieral, Climate, Organic Material, Vegetation, Topography, Time
The type of weathering that breaks the rocks down in size ONLY.
Mechanical
Glaciers are formed in areas where more snow falls than melts.
High in mountain valleys where temperatures seldom rise above freezing
Snow builds up year after year
Pressure of snow layers above squeezes the layers below
The snow compacts and forms ice
What is the relationship between density & salinity
They are directly related, the higher the salinty the higher the density. The lower the salinty the lower the density
What are the three things that can happen when water hits the ground
Run off, Soak in, evaporate
