Chapter 4

Mr. Trawinski

TermDefinition
abrasion physical weathering caused by friction between rock particles
agent of erosion Wind, water or ice (glaciers)
bedrock Solid layer of rock beneath the soil horizons
chemical weathering changes the mineral composition of rock, forming new substances
deposition Settling or release of sediments by agents of erosion
discharge Quantity of water flowing past a certain point in the stream per unit of time
erosion Transportation of weathered material (sediments) by wind water or ice away from thier place of origin
flotation Transportation of particles along the surface of a stream
frost action form of physical weathering in climates with seasonal weather changes above and below zero degrees
glacial erratic Large rock that has been transported by a glacier
glacier large mass of slowly flowing ice
graded bedding Layers of sediment that change from course particles at the bottom of each layer to progressively finer particles toward the top
horizontal sorting Gradual change in the size, density and shape of particles deposited when a stream slows on reaching calm water
humus Organic remains on the top layer of soil - best for growing crops
ice age Period when glacial ice covered large parts of the continents
leaching Process by which groundwater carries dissolved minerals deeper into the soil as water infiltrates the ground
mass movement Downhill movement of rock or sediment without being carried by wind, water or ice (same as mass wasting)
meander Natural looping bend or S shaped curve in a stream
mass wasting Downhill movement of rock or sediment without being carried by wind, water or ice (same as mass movement)
outcrop bedrock exposed at the earth's surface
physical weathering changes the size and/or shape of the rock without changing the chemical composition
precipitate Salt crystals that form and settle out of a solution
precipitation Process that involves substances substances settling out of a saturated solution
residual soil Soil that remains on the top of the bedrock where it is formed
sediments Rocks that have broken into fragments
soil Weathered rock mixed with organic remains at the top of the lithosphere
soil horizon Layers within the soil showing a particular stage of soil development - slow formation
solution Mixture in which particles are so small they can't be filtered out of the water
sorted Separated by particle size or other characteristics
stream discharge Amount of water flowing in a stream
stream velocity Speed at which a stream flows
striation Parallel scratches on the surface of a rock caused by the movement of a glacier
suspension Fluid in which particles that can can be filtered but they are too small to settle on their own
till Unsorted sediments deposited directly by glacial ice
transported soil Soil eroded and deposited AWAY from its parent bedrock
unsorted deposit Sediment left by melting glacial ice (mixture of clay, sand, cobbles and boulders)
vertical sorting Sorting of particles from bottom to top in a layer
weathering breakdown of rock due to chemical or physical changes
What is usually required for chemical weathering? Water
Give an example of chemical weathering Rusting of iron
What speeds chemical weathering? Heat
What happens to rock during frost action? Water seeps into cracks in the rocks, water freezes and cracks in the rock get bigger each time
What controls the stream velocity? The slope (gradient) and the stream discharge (amount of water flowing in a stream

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
