Weathering
What is weathering?
breaking down rock and minerals into smaller pieces
What is erosion?
Sediment and rock that is dropped off in a new place.
deposition
A river flows over the land and creates this.
A canyon
Stored energy
potential energy
A rock is broken in half. How did it happen?
DOUBLE JEOPARDY!!! (question is worth twice the number of points)
water repeatedly freezing and thawing
What forces cause erosion?
Wind, water, ice, gravity
What forces causes deposition to occur?
wind and water
Wind moving sand and placing it in a new place, creates this landform.
sand dunes
Light travels in.....
rays
What forces can cause weathering to occur?
wind, water, ice
A canyon is formed by....
What is the difference between erosion and deposition?
Erosion moves rock and sediment and deposition drops it off.
Wave action, erode and deposit sand and rock, causing this to constantly be changing.
beaches
The remains of animals and plants that lived millions of years ago in a marine environment. Over millions of years, the remains of these animals and plants were covered by layers of sand, silt, and rock. Heat and pressure from these layers turned the remains into what we now call __________
Oil
The Grand Canyon was formed by _____ and ______.
weathering and erosion
What causes a beach to always change?
waves, causing erosion and deposition
Deposition of rock and sediment.
Snow melt makes this rise and flow stronger, eroding the shoreline.
River
Electrical energy is transformed into energy that you can see.
Light energy
A rock arch was formed in the desert by the process of weathering. What force shaped the rock arch formation?
wind
What causes a valley to be formed?
A glacier
Ice breaks a rock apart and the melting snow moves it downstream, where it is dropped off in a lake. What part is deposition?
"where it is dropped off in a lake"
This is formed when rivers deposit rock and sediment at their mouth.
Delta
A closed circuit allows energy to flow. This is called a _______ circuit.
DOUBLE JEOPARDY!!! (question is worth twice the number of points)
Complete circuit
