Water Formations
As waves crash against a mountain, a formation occurs. This formation is able to be seen when the tide recedes. What is this formation called?
Continental Shelf
Minnesota is known as “The land of 10000 Lakes”. How were these lakes formed?
The lakes were formed by glaciers that carved out land that formed lakes
Chemical weathering is caused by _________?
acid rain (or water mixing with CO2 to become acidic)
Wind, ice movement and water movement are all forms of _________ forces
external forces.
What is the triangular formation made at the mouth of a river?
delta or alluvial fan
What is an example of wind deposition?
How does oxygen influence chemical weathering?
Oxygen oxidizes minerals to alteration products (ie rusting iron)
TRUE/FALSE: Faults are formed when hot, high pressure rock is compressed.
false, BENDS are formed when hot, high pressure rock is compressed.
True or false: moving water is the fastest form of physical weathering
true
What is an example of formation caused by wind?
arches, rock formations, valleys, sand dunes
_______________ break down soil as they remove nutrients, while adding chemicals that weather particles of rock and even the bedrock below the soil.
organisms (plants, bacteria)
What are the three main external forces of Earth that cause erosion?
What prevents severe erosion by reducing the energy of waves by breaking them ?
Sand bars
What are 3 physical features created by glacier movement?
plains, lakes (kettle), moraines, U shaped valleys, eskers (ridges)
How does chemical weathering contribute to the formation of soil?
chemical reactions can cause the rock to become weaker and more prone to physical weathering and erosion, leading to the formation of soil and other physical features on the Earth's surface.
What internal and external forces form mountains?
The movement of tectonic plates and wind.
What are 3 physical features that waves help form?
barrier islands, sea caves, sea arches, sea stacks,
What are the piles of sediment and rock left from a glacier?
moraines
What are the four major causes of chemical weathering?
water, CO2, salt, oxygen
What are 4 examples of internal forces that contribute to the formation of physical features?
plate tectonics, magma movement, geological uplift, subsistence,
