Constructive Processes
What is a volcano?
A volcano is an opening in the Earth's crust where lava, ash, and gases can escape from below the surface.
What is erosion?
Erosion is the process by which soil and rock are removed from the Earth's surface by wind, water, or ice.
What is a delta?
A delta is a landform created at the mouth of a river where it meets a body of water, formed by sediment deposition.
What is a landslide?
A landslide is the movement of rock and soil down a slope, often caused by heavy rain or earthquakes.
How can we identify a mountain?
A mountain can be identified by its peak, height, and steep slopes compared to surrounding landforms.
What is deposition?
Deposition is the process where materials are added to a landform, such as sand being deposited by wind or water.
What is a landslide?
A landslide is the movement of rock and soil down a slope, often caused by heavy rain or earthquakes.
What is a canyon?
A canyon is a deep gorge or valley, often carved out by the erosion of a river over time.
What are tectonic plates?
Tectonic plates are massive pieces of the Earth's lithosphere that move and interact with each other, causing earthquakes and volcanic activity.
What tools can help us study the Earth?
Tools like maps, satellite images, and GPS technology help us study and understand the Earth's features.
What is a mountain range?
A mountain range is a series of connected mountains formed by tectonic processes like folding and faulting.
What is weathering?
Weathering is the breaking down of rocks and minerals through processes like wind, water, and temperature changes.
What is a plateau?
A plateau is a flat elevated landform that rises sharply above the surrounding area.
What is a sinkhole?
A sinkhole is a depression or hole in the ground caused by the collapse of a surface layer, often due to erosion.
What is a topographic map?
A topographic map is a detailed representation of the Earth's surface, showing elevation, landforms, and features.
How do earthquakes create new land?
Earthquakes can cause shifts in land, creating new landforms like fault lines or causing uplift of land.
How does a tsunami destroy land?
A tsunami can flood coastal areas and erode beaches, causing significant destruction to habitats and human structures.
What is an island?
An island is a piece of land surrounded by water on all sides.
How does the water cycle affect land?
The water cycle contributes to erosion, sediment transport, and landform changes through precipitation, runoff, and evaporation.
How do scientists measure erosion?
Scientists measure erosion using tools like erosion pins, sediment traps, and GPS to track changes over time.
What is a floodplain?
A floodplain is the flat land adjacent to a river that is prone to flooding, formed by sediment deposits during floods.
What is the role of glaciers in shaping the land?
Glaciers carve out valleys and can create landforms like fjords and drumlins through their movement and melting.
What is a valley?
A valley is a low area of land between hills or mountains, often with a river running through it.
What is the rock cycle?
The rock cycle describes the process by which rocks are formed, broken down, and reformed through geological processes.
What is satellite imagery?
Satellite imagery is pictures of the Earth's surface taken from satellites, which help us observe and analyze landforms and changes.
