🌎 EARTH'S SYSTEMS
Which Earth system includes all of Earth's water?
What is the hydrosphere?
What force pulls water and objects downhill?
What is gravity?
What is weathering?
What is the breaking down or changing of rock?
What process breaks rock down?
What is weathering?
Name one major agent of erosion.
What is Water, wind, ice, or gravity.
Which Earth system includes rocks, soil, and land?
What is the geosphere?
Which energy source drives wind and evaporation?
What is the Sun?
A rock breaks into smaller pieces but stays the same material. What type of weathering is this?
What is physical weathering?
What process moves sediment from one place to another?
What is erosion?
What agent of erosion can form sand dunes?
What is wind?
Which Earth system includes plants, animals, and humans?
What is the biosphere?
Volcanoes and earthquakes are mainly caused by energy from where?
What is Earth's interior?
Acid rain reacts with and changes a rock. What type of weathering is occurring?
What is chemical weathering?
What process occurs when sediment is dropped in a new location?
What is deposition?
What is a glacier?
A large mass of ice that slowly moves across land.
A student breathes air, drinks water, and walks on the ground. Which three Earth systems are involved?
What are the atmosphere, hydrosphere, and geosphere?
A river flows downhill and carries sediment with it. What energy source helps cause this movement?
What is gravity?
Water enters a crack in a rock, freezes, expands, and makes the crack larger. What type of weathering is this?
What is physical weathering?
A river is moving very quickly. Is more likely to cause: erosion or deposition?
What is erosion?
A steep hillside becomes unstable after heavy rain. Rock and soil suddenly move downhill. What process is occurring, and what is the main force involved?
A landslide is occurring, and gravity is the main force.
Why are Earth's four systems considered connected?
What is because matter and energy move between the systems and the systems interact with one another.
A student observes wind moving sand across a beach. Explain how energy is causing matter to move.
What is energy from the Sun helps create wind, and the wind moves the sand.
A rock is broken into many smaller pieces. Why might the smaller pieces weather faster?
The smaller pieces have more surface area exposed to weathering.
A river slows down as it reaches a larger body of water. What happens to the sediment it was carrying?
The river deposits the sediment, which can help form a delta.
A river flows down a mountain. Gravity pulls the water downhill. The fast-moving water carries pieces of rock. Farther downstream, the river slows and drops the sediment.
Identify the three geologic processes happening in this situation and explain what happens during each one.
Weathering: Rock is broken down into smaller pieces.
Erosion: Moving water carries the sediment.
Deposition: Slower water drops the sediment.
