Which of these is a destructive process that breaks down rocks into smaller pieces?
A) Weathering
B) Deposition
C) Volcanic Eruptions

A delta is a landform found at the mouth of a river. What process forms it?
Deposition
Which piece of technology measures the strength and location of an earthquake?
A) Seismograph
B) Anemometer
C) Microscope
D) Barometer
A) Seismograph
If you are modeling "deposition" in a tray of sand and water, what would you see?
Sand settling at the bottom when water slows
How do sand dunes form in a desert or on a beach?
Wind deposits sand in one place over time
What is the main difference between weathering and erosion?
Weathering breaks it; erosion takes it
If you see a canyon with a river at the bottom, what is the best evidence that water caused it?
The walls match the path of the river
Which human-made structure is built to hold back water and control floods?
A) A seismograph
B) A jetty
C) A dam
D) A skyscraper
In a classroom model using a stream table (a tray tilted with sand and a water hose), a student increases the "slope" by propping the tray up higher. What destructive process are they most likely trying to collect data on?
Erosion
Mountains can be formed by which process?
Constructive force of tectonic plates pushing together
Glaciers are huge sheets of ice that carve out U-shaped valleys. This makes them a...?
Destructive force
Which of these is most likely caused by an earthquake?
A) Weathering of a statue
B) A sand dune
C) A delta
D) A surface crack or fault line
D) A surface crack or fault line
How do satellites help people deal with constructive and destructive processes?
They track changes like beach erosion or volcanic activity
In a model of a canyon, what material best represents the "destructive" force?
Running water
What is the primary constructive process that happens after a volcanic eruption?
The cooling of lava into new land
What role does "gravity" play in destructive processes?
It pulls rocks and soil down slopes/landslides
Farmers plant rows of trees (windbreaks) to limit what process?
Wind erosion
Monitoring gas levels and shaking near a volcano is a way to do what?
Predict a destructive process
A levee is most similar to which other human-made structure?
A dam
Which of the following would be the best scientific argument for why a volcano is a constructive force?
Lava cools and hardens to form new rock
Which of the following is an example of an "impact of organisms" acting as a destructive force?
A. Coral reefs growing in the ocean
B. Birds building nests in trees
C. Beavers building a dam with sticks
D. Tree roots growing into and cracking a sidewalk
D. Tree roots cracking a sidewalk
A sea wall is built along a coastline. What is the most likely reason for this?
To protect the land from wave erosion
How does beach nourishment (adding sand) help limit destructive processes?
It replaces sand lost to erosion
In a classroom model of a hillside, a student covers one side of the "mountain" with strips of carpet or craft moss while leaving the other side as bare dirt. When they "rain" on both sides with a spray bottle, what scientific evidence are they collecting about the role of plants (organisms)?
The ability of plant roots (represented by the moss/carpet) to hold soil in place and prevent erosion
