Earth's Spheres
What's the definition of geosphere?
includes rocks/ minerals from Earth's surface to core
In a cold environment, snow accumulates on a glacier, increasing its size. This process involves:
1 - (A) deposition (B) melting (C) erosion,
which 2 - (A) can affect (B) does not affect sea levels over time.
1 - (A) deposition
2 - (A) can affect
Which of the following is an example of physical weathering?
A. Rocks breaking apart due to freeze-thaw cycles
B. Acid rain dissolving limestone
C. Iron in rocks rusting due to exposure to water and air
D. Roots releasing chemicals that weaken rock
A. Rocks breaking apart due to freeze-thaw cycles
How do the geosphere and the hydrosphere interact during a volcanic eruption?
A. Magma releases gases into the atmosphere.
B. Volcanic ash affects plant growth.
C. Lava heats nearby rivers and streams.
D. Earthquakes trigger landslides.
C. Lava heats nearby rivers and streams
During a drought, the soil in a region becomes very dry and begins to crack. This is an example of:
1 - (A) evaporation (B) erosion (C) condensation,
which 2 - (A) can affect (B) does not affect plant growth in the area.
1 - (A) evaporation
2 - (A) can affect
Which natural force is primarily responsible for erosion on sandy beaches?
A. Earthquakes
B. Ocean waves
C. Ice glaciers
D. Plant roots
B. Ocean waves
Which of the following is an example of an interaction between the atmosphere and the biosphere?
A. Plants releasing oxygen during photosynthesis
B. Ocean waves eroding a cliff
C. Wind carrying sediment across a desert
D. Lava cooling to form rock
A. Plants releasing oxygen during photosynthesis
When heavy rainfall occurs in a mountainous region, water flows down the slopes and causes soil to move. This is an example of:
1 - (A) flooding (B) weathering (C) erosion,
which 2 - (A) can change (B) does not change the landscape over time.
1 - (C) erosion
2 - (A) can change
How does chemical weathering differ from physical weathering?
A. Chemical weathering changes the chemical composition of rocks, while physical weathering breaks rocks into smaller pieces without altering their composition.
B. Chemical weathering only occurs near water, while physical weathering only occurs in dry areas.
C. Chemical weathering happens quickly, while physical weathering takes millions of years.
D. Chemical weathering strengthens rocks, while physical weathering weakens them.
A. Chemical weathering changes the chemical composition of rocks, while physical weathering breaks rocks into smaller pieces without altering their composit
Which of the following is an example of an interaction between the hydrosphere and the geosphere?
A. River sediment depositing on a floodplain
B. Trees absorbing water from soil
C. Volcanoes releasing water vapor into the air
D. Wind eroding a mountain's surface
A. River sediment depositing on a floodplain.
Explanation:
This is an interaction between the hydrosphere (water in the river) and the geosphere (land and sediment on the floodplain). The river (hydrosphere) carries sediment and deposits it on the floodplain (geosphere), showing a direct interaction between water and land.
A hurricane moves across the ocean, causing high waves and pushing water onto the coastline. This results in:
1 - (A) flooding (B) evaporation (C) precipitation,
which 2 - (A) can reshape (B) does not affect the coastline.
1 - (A) flooding
2 - (A) can reshape
Which process demonstrates the role of water in mechanical weathering?
A. Water dissolves minerals from rock, creating caves.
B. Water freezes in cracks, expanding and causing the rock to break apart.
C. Water reacts with oxygen to form rust on iron-rich rocks.
D. Water combines with carbon dioxide to form acid rain.
B. Water freezes in cracks, expanding and causing the rock to break apart.
How does groundwater interact with other components of the water cycle?
A. It remains permanently underground and does not interact with other spheres.
B. It contributes to streams, rivers, and oceans through infiltration and springs.
C. It bypasses the evaporation and precipitation steps of the cycle entirely.
D. It forms clouds directly from the ground without evaporating.
B. It contributes to streams, rivers, and oceans through infiltration and springs.
Strong winds blow across a desert, lifting sand and forming dunes. This is an example of:
1 - (A) condensation (B) erosion (C) flooding,
which 2 - (A) can change (B) does not change the landscape.
B) erosion
2 - (A) can change
In what way does wind contribute to both erosion and weathering in desert environments?
A. Wind carries sand particles that polish rock surfaces and transport sediment.
B. Wind erodes rock chemically by reacting with atmospheric gases.
C. Wind strengthens rock by compacting loose sediment into solid layers.
D. Wind cools desert rocks, slowing down physical weathering processes.
A. Wind carries sand particles that polish rock surfaces and transport sediment.
