To investigate Earth’s landforms and discover how they are made! You must proceed with caution!
All around you things will be destroyed and built up!
Rocks change shape, size and/or form due to water or ice movement, freeze and thaw, wind, plant growth, gases in the air, pollution and catastrophic events such as earthquakes, mass wasting, flooding and volcanic activity
Watch how weathering and erosion work together to wear away rock!
Weathering is a group of processes that break down rocks and sediment into smaller particles.
Some weathering processes take a long time to occur, while some weathering processes occur quickly.
Weathering can be caused by water, wind, ice, or plant roots.
It is a “destructive” process.
Take a look at he link below to watch erosion in action!
Erosion is a process that transports rock, soil or sediment to a different location.
Water, wind and ice physically remove and carry (erosion) rock, soil and sediment and deposit the material in a new location.
Erosion is a “destructive process”
Watch as the sediment is deposited.
Deposition happens when erosion deposits the
material in a new location.
The material builds up to make new landforms.
Deposition is a “constructive” process
Flooding is when water rises and overflows onto dry land.
Water saturates the ground and washes away eroded rocks, soil and sediment. The water expands to cover more land and recedes back to its normal banks.
Flooding is a “constructive” and “destructive” process
What does flooding do to the rocks, soil, and sediment?
How does flooding construct and destruct the land around it?
Watch the incredible glaciers as they move massive amounts of rocks and sediment!
The very slow movement of glaciers
Glaciers are a large body of ice moving slowly down a slope or valley or spreading outward on a land surface
Glaciers erode the land and deposit the land in new places.
Glaciers are a “destructive” and “constructive” processes.
What would the movement of a glacier
do to a mountain?
LOOK at the pictures!
A shaking or trembling of the earth that is caused by volcanic or tectonic activity
As plates in the earth move past each other and cause friction, they create a vibration that makes the earth shake and move.
Earthquakes are a “destructive” process
What causes an earthquake?
Watch the destructive and constructive force of volcanoes!
Molten or hot rock and steam coming out of a vent in the crust of the earth
A hill or mountain made up of material that comes out of a whole or crack in the earth
Something of explosively violent potential
Volcanic activity is a “destructive” and “constructive” process.
- Watch the videos and explain:
How is it destructive?
How is it constructive?
