Weathering/Erosion
Water, temperature, ice, gravity and wind cause this type of weathering.
What is physical weathering?
Where a river dumps into a bigger body of water and sediment is deposited?
What is a delta?
Which of the following best describes how a landform could be formed (constructed) by moving wind, water, or ice?
A. A river deposits sediment to form a delta.
B. Lava cools and hardens to form a new mountain.
C. A glacier gets smaller due to increasing temperatures.
D. A coastline becomes smaller over time because of wave action.
What is A
The ONE thing that can be changed in an experiment.
What is the independent variable?
Give an agent of erosion.
What is wind, water, ice, and gravity?
The building up of sand on the beach due to an obstacle like grass or plants?
What is a sand dune.
After years of exposure to the weather, the details on the marble statue have begun to wear away. What is most likely the cause of this weathering?
A. Abrasion has most likely caused this statue to weather.
B. Lichens have most likely caused this statue to weather.
C. Oxygen in the air has most likely caused this statue to weather.
D. Acid (Carbonic acid) in rainwater has most likely caused this statue to weather.
What is a D?
John is investigating the effects of temperature changes on rocks. He learns that as rocks are repeatedly heated and cooled, they expand and contract, leading to the weakening and eventual breakdown of the rocks. This phenomenon is an example of which type of weathering process?
What is a physical weathering?
What is a River?
Lichens breaking down a rock is an example of what type of weathering?
What is chemical weathering?
What is being measured/tested in an experiment is called what variable?
What is the dependent variable?
A geologist examines a sample of beach rock and discovered that it was composed of grains of sand squeezed tightly together. The quartz grains were glued together by narrow bands of calcium carbonate. What geologic event occurred that led to the formation of this Sedimentary rock?
A. Deformation
B. Melting and cooling
C. Weathering and erosion
D. Compaction and cementation
What is D.
The breaking down of rocks into smaller pieces?
What is weathering?
The laying down of rock in a new place?
What is deposition?
To ensure that she has reliable results, Daisy conducts 6 trials. What would the six (6) trials be considered an example of?
A. Repetition
B. Replication
C. Analyzing data
D. Scientific inquiry
What is repetition
Imagine that a large area of sedimentary rock gets moved deeper into Earth. There, rising temperatures and high pressure change the rock. Eventually the rock melts from the high temperatures and pressure. After some time in those conditions, the rock is released from a volcano and there is a time of cooling. What type of rock is formed?
What is an igneous rock?
Which of the following changes to the earth’s surface can be caused by weathering due to wind or water?
A. The path of a river can be caused by wind and water, but not the shape of a coastline.
B. Both the shape of a coastline and the path of a river can be caused by wind or water.
C. The shape of the coastline can be caused by wind or water, but not the path of a river.
D. Neither the shape of a coastline nor the path of a river can be caused by wind or water.
What is B
What is an agent of weathering?
What is wind, water, ice, temperature, gravity, plants, animals?
In an experiment the one thing that nothing happens to ex. cup not filled with water when the rest of the cups are filled.
What can form from surface event processes?
A. Metamorphic rock
B. Magma and Sediment
C. Igneous rock and Magma
D. Sedimentary Rock and Sediment
