Do erosion and weathering change Earth's surface quickly, or over time?
Over time. Think about how long it has taken us to get some sediment at the bottom of our weathering bottles.
lava
True or false
Weathering is the breaking down of rock over time.
True
These cans are an experiment that we are doing in class that represent what?
weathering
A sudden burst or discharge of lava is called a _________.
volcano
When a volcano erupts, does it change earth's surface quickly or slowly?
Quickly because it erupts suddenly.
Is the forming of a canyon quick, or is this something that happens slowly?
Slowly. It can take MILLIONS of years for a canyon to form.
Weathering involves movement, but erosion does not.
False! Erosion involves movement, not weathering.
The Grand Canyon was once a place where a river traveled through a mountain. Over time, the river formed the canyon. Is this weathering or erosion?
Erosion because the river carried land and rocks to a new place.
This is an event that happens quickly. A large amount of land that suddenly slides down the side of a mountain or hill is called a ________.
landslide
True or false
Although Earthquakes happen fast and glaciers happen slow, both can both cause landforms like mountains or valleys.
True
Erosion is the _________ of small broken down rocks and pieces of land to a new place. Erosion has helped form mountains, canyons and other landforms.
movement
Erosion because the land was moving to a new location.
A tropical storm with heavy wind and heavy rain is called a _________.
hurricane
Name something we've learned about that changes Earth's surface quickly.
volcano erupting, tornado, landslide, earthquake, hurricane, flood.
This a a cone volcano. It erupts violently because it has _____ lava. (Hint: what kind of lava were you able to form a mountain with?)
Thick
Answers will vary. Sample answer: Weathering breaks down rocks first, and then erosion takes those pieces of broken down rock and moves them to a new place.
Is the following picture of weathering or erosion? The ocean has carried the land to a new place.
erosion
A destructive funnel shaped cloud that travels across the land is a ________.
tornado
Name something we've learned about that changes Earth's surface slowly.
beach erosion, wind erosion, a valley formed by a glacier, weathering, rock broken down by ice.
Tell me why we know that this volcano won't erupt violently. (Hint: Think back to our volcano experiment and what we learned is inside a volcano)
Name the three things that can cause erosion. These three things are also called "agents of change" (hint: glaciers, rivers, hair dryer)
wind, water, and ice
What process does this rock show? (Hint: check the category game)
weathering
A large amount of water covering an area that is usually dry is a ___________.
