What makes up till?
Clay, silt, sand, gravel and rocks
100
What is the only liquid on earth that expands as it freezes?
Water
100
What are the two ways land is broken down?
Weathering & Erosion
100
Explain the two depositions formed from wind erosion.
1. Loess-Large deposits of sand sediments 2. Sand Dunes-wind blown sediment areas of varying shapes and sizes
100
What do we call soil that is made of equal parts of clay, silt and sand?
Loam
200
What two processes do glaciers erode the land? Explain each.
1. Plucking- the moving glacier picks all items in its path. 2. Abrasion- the items attached to the glacier scratch/scrap the land as it moves
200
What land formation forms on the ceilings of caves?
Stalactites
200
A finger-like projection into a large body of water formed from deposition is called?
A spit.
200
List and explain the four types of chemical weathering.
1. Water - Water can dissolve rock 2. Oxidation- Iron mixes with Oxygen and water 3. Carbon Dioxide- Carbonic Acid 4. Living organisms- Acids through plant roots 5. Acid Rain- Acids dissolve rock
200
Soil formation begins with the weathering of?
Bedrock
300
What is responsible for mass movement?
Gravity
300
The texture and particle size of soil determines what?
How much air and water the soil can hold (NOT SOIL FERTILITY)
300
***DAILY DOUBLE*** What are four types of mass movement? Explain each.
1. Landslide-sudden drop of rock and soil 2. Mudslide-water mixes with soil and causes sudden drop 3. Slump-fast, movement of a large piece of land 4. Creep- slow movement downhill
300
Explain the two types of glaciers.
1. Valley Glaciers- form in between mountains in valleys 2. Continental Glaciers- form over entire large continents or islands
300
The process of wearing down and carrying rock is called?
Erosion
400
Ice blocks left behind by the continental glacier melted to form what?
Kettles
400
A stream that flows into a larger river is called?
Tributary
400
Sediment deposited where a river flows into an ocean and builds up into a?
Delta.
400
What are the three parts of the cycle that build up and wear down landforms on the earth?
Erosion-Weathering- Deposition
400
What is the process called where some of the sediment moves down the beach with the current?
Longshore drift.
500
A river flowing across a wide flood plain that forms a loop like bed is called?
Meander
500
Tiny grooves in the soil formed formed by runoff and gravity are called?
Rills
500
What is karst topography?
Any of the following terms: -Has limestone near the surface -Has sinkholes, caverns and deep valleys
500
Sediment that glaciers deposit is called?
Till

***Daily double*** List and explain the three soil conservation methods.
1. Contour Plowing-farmers plow fields along the curves of a slope. 2. Crop Rotation- rotates the crops each season in an area of land. 3.Conservation Plowing- dead weeds and dead crops are plowed back into the soil.
