Example Question #1 : Observe Effects Of Weathering On Rate Of Erosion
Steven and his sister Sasha are making observations about erosion and the rate of movement of materials. They are looking at different bodies of water and how small rocks are being moved. Sasha took a piece of broken rock about 2 cm and threw it into each body of water to observe what happened. They followed the material if it moved to get a distance of travel. They recorded the data below.
What observations can be made regarding the bodies of water and distance eroded materials travel?
A slower flow of water can carry more eroded material than a faster flow of water.
A faster flow of water is not able to carry eroded material as far as a slower flow of water.
A slower flow of water is not able to carry eroded material as far as a faster flow of water.
Fast-moving and slow-moving flows of water carry the same amount of eroded materials the same distance.
A slower flow of water is not able to carry eroded material as far as a faster flow of water.
Sasha and Steven are making observations about how different bodies of water move eroded materials. Rivers are a fast-moving flow of water, lakes and ponds are primarily standing water, and streams are slow-moving bodies of water. Based on the data, they measured and observed the river moved the materials the farthest distance. A connection can be made about the rate of running water and how materials will be eroded or carried away. The faster a body of water moves, the further and faster sediment and eroded materials will move.
Example Question #2 : Observe Effects Of Weathering On Rate Of Erosion
What does the term "weathering" mean? Example: Gabriel studied the effects of weathering on the Grand Canyon by taking daily measurements during his summer internship.
The state of the atmosphere at a place and time as regards heat, dryness, sunshine, wind, rain, etc.
Wear away or change the appearance or texture of something by prolonged exposure to wind, water, ice, and vegetation
Expressing a doubt or choice between alternatives
Movement something that is broken by prolonged exposure to wind, water, ice, and vegetation to a new place
Wear away or change the appearance or texture of something by prolonged exposure to wind, water, ice, and vegetation
Weathering and erosion are usually two terms used simultaneously and together, but each has its independent definition and usage. Weathering used in this context means the wearing away or changing the appearance and texture of something that is being worn away and broken down by the wind, water, ice, and vegetation. Water seeps into the rocks and freezes time after time, which slowly breaks the rock into pieces, plant roots grow through cliffsides and rocks, and the wind and rain batter shorelines with tiny fragments of sediments and water drops. All of these actions slowly break the rocks, shorelines, and cliff faces down.
Example Question #11 : Weather And Erosion Rate
What does the term "erosion" mean in the context provided?? Example: Gabriel studied the process of erosion on the coast of North Carolina by comparing aerial maps and measurements over the last 100 years.
come safely through a storm
The process by which the surface of the earth is worn away and moved by the action of water, vegetation, winds, and ice
The removal of a person's authority, rights, or confidence
Breaking down of rocks, soil, and minerals as well as wood and artificial materials by the Sun
The process by which the surface of the earth is worn away and moved by the action of water, vegetation, winds, and ice
Weathering and erosion are usually heard used together, but each has its definition and essential part of shaping our landscapes over time. Erosion is the process by which the surface of the earth is worn away and moved by the action of water, vegetation, winds, and ice. As fragments of rock or debris are broken off through the process of weathering, the materials are moved and worn away by erosion. A river will carry sediment downstream and move it to new locations as the process of weathering continues.
Example Question #12 : Weather And Erosion Rate
What type of erosion would occur most frequently in the Mohave Desert?
Glacial erosion
Water erosion
Wind erosion
Vegetation erosion
Wind erosion
The type of erosion most likely to occur in the Mohave Desert would be wind erosion. The desert would not experience glacial erosion because there are no frozen blocks of ice. In the desert, there is limited water and vegetation, so neither of those would be likely to cause erosion. The desert does experience high winds and sandstorms, which would cause movement of the materials and sediment in the area.
Example Question #13 : Weather And Erosion Rate
Which of these is an example of erosion?
Water sitting in a pond
Sunshine on a mountain
Rain breaking down rock
Wind blowing away sediment
Wind blowing away sediment
Erosion is the movement of materials and broken down debris from the process of weathering. The correct answer choice must address the movement of materials, not just the breaking down of materials. "Wind blowing away sediment" is the right answer because it demonstrates the movement of sediment by the wind; sediment is material that settles in water or on shorelines, so this is a reasonable type of debris that would be picked up and moved.
Example Question #14 : Weather And Erosion Rate
The picture below shows a process that happens when rocks and soil are moved from one place to another.
What is the name of this process?
Fertilization
Erosion
Pollination
Weathering
Erosion
Weathering and erosion are usually two terms used simultaneously and together, but each has its independent definition and usage. Weathering used in this context means the wearing away or changing the appearance and texture of something that is being worn away and broken down by the wind, water, ice, and vegetation. Erosion is the process by which the surface of the earth is worn away and moved by the action of water, vegetation, winds, and ice. As fragments of rock or debris are broken off through the process of weathering, the materials are moved and worn away by erosion. A river will carry sediment downstream and move it to new locations as the process of weathering continues. The question has the key phrase "moved from one place to another," which lets readers know movement is taking place, which is the process of erosion.
Example Question #7 : Observe Effects Of Weathering On Rate Of Erosion
True or False: Constant strong winds could accelerate the rate of erosion.
False
True
True
Erosion is the process by which the surface of the earth is worn away and moved by the action of water, vegetation, winds, and ice. As fragments of rock or debris are broken off through the process of weathering, the materials are moved and worn away by erosion. Constant strong winds could speed up the process of erosion compared to a soft breeze blowing occasionally.
Example Question #15 : Weather And Erosion Rate
Steven and his sister Sasha are making observations about erosion and the rate of movement of materials. They are looking at different bodies of water and how small rocks are being moved. Sasha took a piece of broken rock about 2 cm and threw it into each body of water to observe what happened. They followed the material if it moved to get a distance of travel. They recorded the data below.
Which body of water likely has the greatest effect on the rate of erosion?
A river
A pond
A lake
A stream
A river
Sasha and Steven are making observations about how different bodies of water move eroded materials. Rivers are a fast-moving flow of water, lakes, and ponds are primarily standing water, and streams are slow-moving bodies of water. Based on the data, they measured and observed the river moved the materials the farthest distance. A connection can be made about the rate of running water and how materials will be eroded or carried away. The faster a body of water moves, the further and faster sediment and eroded materials will move.
Example Question #11 : Weather And Erosion Rate
Erosion takes place when rock or sediment is
broken into pieces.
transported to a new location.
changed into something new.
dropped from a high ledge.
transported to a new location.
