Weathering\Erosion
How does weathering affect Earth and what is weathering?
It breaks rocks and rocks surfaces by wearing it and chemically alter rocks. The mechanical and chemical processes that change objects on Earth's surface.
What is deposition?
The laying down or settling of eroded material
What does magma form?
It forms igneous rock.
What is a metamorphic rock?
They are rocks that have changed due to extreme temperature or pressure. An example of one is marble and quartz.
What are clastic rocks?
Rocks that are made up of broken pieces of minerals and rock fragments.
what are the weathering agents
Water, wind and ice
What are the depositional environments?
Swamps,deltas,beaches,and ocean floor
What is magma?
Molten or liquid rock underground.
What are foliated rocks?
Rocks that contain parallel layers of flat and elongated minerals. An example of one is gneiss.
How does sedimentary rock form?
When rock material that forms where rocks are broken down into smaller pieces. Two examples of these are sandstone and limestone.
What happens to weathering material
It Erodes
What is uplift?
It is the upward vertical motion of Earth's surface.
How does igneous rock form ?
When magma cools. Two types are obsidian and basalt.
What are non-folitated rocks?
Metamorphic rocks that have mineral grains with a random, interlocking texture.An example of one is greenstone.
What are chemical rocks?
When minerals crystallize directly from water.
What are the agents of Erosion,and what is erosion?
Water,Wind,Glaciers,and Gravity. The removal of weathered material from one place to another.
What does vertical motion do to plate boundaries?
It applies great force that can break rocks or can change the shape.
What are extrusive rocks?
It is when volcanic material erupts and cools and crystallizes on Earth's surface. A example of extrusive rock is obsidian.
What is contact metamorphism?
When magma comes in contact with existing rocks and its thermal energy and gases interact with surrounding rock, forming new metamorphic rock.
What are biochemical rocks?
Sedimentary rocks that were formed by organisms or contains the remains of organisms.
What is mechanical and chemical weathering?
When physical processes naturally break rocks into smaller pieces and change the materials that are part of a rock into new materials
What are intrusive rocks?
Rocks that form as magma cools underground. A example of intrusive rock is granite.
What is regional metamorphism?
The formation of metamorphic rock bodies that are hundreds of square kilometers in size.
