Which explanation best describes how a boulder can turn into silt as it moves down a river?
Water washes over the boulder until it is silt-sized.
The boulder hits other rocks or objects and breaks apart.
The boulder moves down the river until it lands in a basin and becomes silt.
A chemical reaction turns the boulder into silt.
You find some soil that is mostly made of clay and silt, but no sand. How might this soil have formed?
Slow-moving water carried the sand downstream and left behind the silt and clay.
Wind blew all the sand away, leaving behind the silt and clay particles.
Silt, clay, and organic material settled out of slow-moving water.
A fast-moving stream washed away all the sand.
You dig up two soil samples and forget to record where they came from. If you return to the soil samples a week later, what are the characteristics of the soils you would use to match them to the locations where they were collected?
Kinds of sediment, color of the samples, and amount of organic material.
How much of the sample (volume) you collected
The amount of moisture in the sample you collected.
The amount of leaves in the sample you collected.
Material that is deposited by water, wind, or ice.

Which size sediments would you find at location X, where the outside of the curve points and water runs faster?
Finer clay particles because it is smallest and the water will carry it farthest.
Cobbles and pebbles because the water is moving faster
Smaller rocks like sand and gravel because the water is moving slower
No sediment at all
Which size sediments would you find at location Y, where the inside of the curve points and water runs slower?
Finer clay particles because it is smallest and the water will carry it farthest.
Cobbles and pebbles because the water is moving faster
Smaller rocks like sand and gravel because the water is moving slower
No sediment at all
Which size sediments would you find at location Z, where the mouth of the river empties into the ocean?
Finer clay particles because it is smallest and the water will carry it farthest.
Cobbles and pebbles because the water is moving faster
Smaller rocks like sand and gravel because the water is moving slower
No sediment at all
Consider the following diagram of a river flowing through a landscape. A rain storm causes a large amount of water to flow through the river in a very short time. Which size sediments would you most likely find at each location, X, Y, and Z? Explain why.
You would find the same sediment at each location.
You would find different sized sediment at each location. At location X you would find cobbles and pebbles because the water is moving faster. At location Y you would find smaller rocks like sand and gravel because the water is moving slower. At location Z you would find finer clay particles because it is smallest and the water will carry it farthest. We saw this when we studied our stream table. The speed of the water and particle size determine how the particles move down the river.
Only the speed of the water determines how particles move down the river. The bigger particles will move down the river faster and farther than the smaller particles.
Only particle size determines how particles move down the river. The bigger particles will move down the river faster and farther than the smaller particles.
A low-lying area where water may accumulate.

Frost Weathering
Physical Weathering
Weathering
Abrasion
The process by which rocks are broken down by breaking and banging.
Frost Wedging
Physical Weathering
Weathering
Abrasion
In this type of physical weathering, the water splits rock when water seeps into cracks, then freezes and expands.
Frost Wedging
Physical Weathering
Weathering
Abrasion
In this type of physical weathering, the roots of a plant (typically a tree) wedge into a crack in a rock and, as the plant grows, splits the rock.
Chemical Reaction
Rock Fall
Root Wedging
Soil
The process in which two or more substances combine to make one or more new substances that have different properties from the original one.
Chemical Reaction
Rock Fall
