Weathering and Erosion
This type of weathering physically breaks rocks into smaller pieces without changing their chemical composition.
What is mechanical weathering?
These are the rapid downslope movements of rock, soil, and debris, often triggered by rain or earthquakes.
What are landslides?
A structure built to control the flow of water, often to create reservoirs or prevent flooding.
What is a dam?
This scientist studies earthquakes and the propagation of seismic waves through the Earth.
Who is a seismologist?
This type of erosion is caused by the movement of water, particularly in rivers, streams, and rainfall.
What is water erosion?
This type of weathering involves the breakdown of rocks through chemical reactions, often with water and air.
What is chemical weathering?
These sudden shaking movements of the Earth's surface occur when tectonic plates shift along fault lines.
What are earthquakes?
This barrier is constructed to prevent flooding by redirecting or controlling the flow of water along rivers or coastlines.
What is a levee?
Name at least 2 benefits of Dams.
What is
Provide additional water for agriculture
Helps prevent flooding
Can direct water to needed areas
Can be used for water storage.
These openings in the Earth's crust allow molten rock, ash, and gases to escape, often forming large cones.
What are volcanoes?
The weathering process in which living organisms, such as plants or animals, contribute to the breakdown of rocks.
What is biological weathering?
These large, rigid pieces of the Earth's lithosphere move and interact to cause seismic activity, mountain formation, and volcanic eruptions.
What are tectonic plates?
These walls are constructed to protect coastlines or infrastructure from the erosive force of waves or tides.
What are barrier walls?
This instrument is used to measure and record the vibrations caused by seismic waves during an earthquake.
What is a seismograph?
This molten rock beneath the Earth's surface eventually cools and solidifies to form igneous rocks when it erupts as lava.
What is magma?
This form of erosion occurs when glaciers move over land, scraping away rocks and soil.
What is ice erosion?
These large landforms are typically formed by tectonic forces such as the collision of plates or volcanic activity.
What are mountains?
This structure is built along coastlines to protect harbors, prevent erosion, and control water currents.
What is a jetty?
How do Levees help coastal areas and cities near them?
What is increase available land and protects it from storm surges?
This is the molten rock that flows from a volcano, as opposed to magma, which is still underground.
What is lava?
This process occurs when strong winds carry away loose soil and sand, often shaping deserts and coastal areas.
What is wind erosion?
This term refers to the process where one tectonic plate moves under another, often leading to volcanic activity and earthquakes.
What is subduction?
This method involves adding sand or other materials to eroding beaches to restore them and protect coastal areas.
What is beach nourishment?
Communities place what along the coastline to stop beach erosion?
What is cement barriers?
These depressions or holes in the ground form when underlying rock, often limestone, dissolves, causing the surface to collapse.
What are sinkholes?
