Weathering and Erosion
The changing of rocks by chemical processes
What is Chemical Weathering?
A great flow of water over an area that is usually dry land
What is a flood?
The drop-off at the edge of the continental shelf
What is the Continental Slope?
The direction a wave moves
What is a circle?
4. Flowing water containing sand and other materials continuously grinds rocks. This results in the formation of cracks in rocks that widen to form caves.
Which natural process does this describe?
What is weathering?
A destructive process that breaks down rocks
What is weathering?
The process of gravity quickly pulling rocks and dirt downhill
What is a landslide?
The area located between the edge of the oceanic crust and the mid-ocean ridge
What is the Ocean Basin?
The daily rising and falling in a regular cycle of Earth’s waters
What are Tides?
5. Amanda read in her science textbook that a flood is a natural process that could be constructive or destructive based on its effects. Which effect of a flood makes it a constructive natural process?
It deposits sediments.
It washes away soil.
It disrupts power lines.
It breaks the surface of rocks.
What is it deposits sediments?
The process by which the surface of the Earth gets worn down. It can be caused by natural elements such as wind, water and glacial ice.
What is to Erosion?
Where the ocean meets the land
Beach or shoreline
An underwater mountain chain where new ocean floor is formed.
What is the Mid-Ocean Ridge?
This occurs because of differences in salinity or water temperatures.
What is a Deep Ocean Current?
Which is the best example of a constructive process?
Deposition
Earthquake
Erosion
Weathering
What is Deposition?
The breaking down of rock by gravity, ice, or plant roots
What is Physical Weathering?
An opening between barrier islands
What is an inlet?
A deep valley that forms when an ocean plate moves below another plate.
What is an Ocean Trench?
Mostly caused by wind moving over the ocean
What is a Surface Current?
The changing of the Earth’s surface can be constructive or destructive. How can a destructive change lead to a constructive change?
A volcanic eruption causes an earthquake.
A landslide blocks a river and causes a flood.
Water weathers rock and the rock pieces are eroded away.
A river erodes soil and deposits it further downstream.
What is A river erodes soil and deposits it further downstream?
The processes by which materials are moved from one place to another place
What is Erosion and Deposition?
Large, flat areas of land that are relatively low.
What are Plains?
The notch, or valley, between the edges of the plates at a spreading plate boundary
What is the Rift Zone?
Tides are caused by this
What is the gravitational pull between the Earth and the Moon?
Which statement impacts erosion the most?
Driving your car instead of walking prevents erosion.
Cutting down trees to build houses causes erosion.
Turning off the lights in your house prevents erosion.
Wasting water on your lawn causes erosion.
What is Cutting down trees to build houses causes erosion?
