Under the Weather Water Water Everywhere Let's Go to the Beach! Soil it Up Potpourri
100
What is mechanical weathering
One of the two major categories of weathering, this produces sediments with the same composition as the parent rock.
100
What are stalactites
These rock formations are the result of groundwater depositing minerals on the roof of a cavern, they often found in limestone caves.
100
What is wind
The largest waves occur when this transfers energy into the water over an extended period of time.
100
What is inorganic
About 50% of the components that make up our soil is this, produced mainly from silicate rock and not living things.
100
What is U
Glaciers tend to carve out valleys in the shape of this letter
200
What is abrasion
This is the type of mechanical weathering in which rocks bump against each other.
200
What is competence
Higher gradient (or slope) increases the size of sediment a stream can carry, also referred to as this.
200
What is a barrier island
This forms when waves deposit sand off the shore into a large pile. Fun fact: Mr. Teague lived on one for three years!
200
What is humus
This is the nutrient-rich remains of dead plants and animals found in soil. It's tasty for plants, not for people!
200
What is sand
Of the three major soil grain sizes, this is the most permeable
300
What is warm / wet
Chemical weathering occurs faster in this type of climate.
300
What is a meander
This is a bend in a river, in which sediment builds up on the inner portion and the outer portion is eroded away.
300
What is a sea wall
This is a structure built along the shore, intended to prevent erosion.
300
What is residual soil
This is the soil that remains where it was formed. It hasn't been transported by wind or water.
300
What is water
Hydrolysis is a form of chemical weathering in which the rock reacts with this liquid
400
What is Carbon Dioxide
This gas reacts with water in the air to create carbonic acid.
400
What is bedload
The sediment that is too large to be suspended in the water settles to the bottom and becomes this. It happens to be the leading cause of streambed erosion.
400
What is a groin
This is a structure built perpendicular to the beach that catches sand carried by the waves and current. Don't laugh at its name!
400
What is at the bottom / in the C Horizon
When looking at a soil profile, this is where I can find the soil that has undergone the least weathering
400
What is the floodplain
If you start a farm, maybe reconsider building it here, the flat area around a river.
500
What is ice wedging
This refers to the type of weathering in which water enters cracks in rocks and freezes, breaking off pieces in the process.
500
What is a delta
This is a wide triangle of deposited sediment found where a river meets a still body of water.
500
What is refraction
This refers to the bending of a wave, caused by the front portion of the wave slowing down before the rest of it as it hits the shore.
500
What is loam
This type of soil is a healthy blend of textures. It's considered the ideal soil for farming.
500
What is deflation
Wind erosion in arid regions removes most of the small sediments, leaving the larger particles and rocks (or desert pavement) behind, in a process called this.
