Weathering and Erosion
What is Weathering?
The mechanical and chemical processes that change objects on Earth's surface over time.
What is a Sedimentary rock?
A type of rock formed from the accumulation and compaction of sediments, like sand, silt, clay, or the remains of dead organisms, which are deposited on the earth's surface over time, eventually becoming cemented together to form a solid rock.
What is a Metamorphic rock?
A rock that has been transformed from its original form due to intense heat and pressure deep within the Earth's crust, causing changes in its mineral composition and texture, essentially "metamorphosing" it into a new rock type.
What is a Igneous rock?
A type of rock formed when molten rock, called magma when underground and lava when on the surface, cools and solidifies.
What is magma?
Molten or liquid rock under ground, cools, imperial crystals.
What is Erosion?
The removal of weathered material from one location to another.
What is chemical rocks?
Forms when minerals crystallize directly from water.
What is foliated rocks?
Contain parallel layers of flat and elongated mineral.
What is intrusive rocks?
Igneous rocks that form as magma cools underground.
What is contact metamorphism?
During magma comes in contact with existing rock, and its thermal energy and gases interacts with the surrounding rock, forming new Metamorphic rocks.
What is mechanical weathering?
The process where rocks break down into smaller pieces due to physical forces like wind, water, temperature changes, and pressure changes, without altering the rock's chemical composition.
What is biochemical rocks?
Is a Sedimentary rock that was formed by organisms or contains the remains of organisms.
What is non-foliated rocks?
Metamorphic rocks that have mineral grains with a random, interlocking texture.
What is extrusive rocks?
When volcanic material erupts and cools and crystallizes on earth's surface, it forms a type of Igneous rock.
What is uplift?
The process that moves large bodies of Earth materials to to higher elevations.
What is chemical weathering?
A process where rocks and minerals break down and change their chemical composition due to chemical reactions with substances like water, air, and acids.
What are 2 examples of a Sedimentary rock?
sandstone, limestone, shale, conglomerate, siltstone, chalk, claystone, and coquina. Ect.........
What are 2 examples of Metamorphic rocks?
slate, marble, gneiss, schist, quartzite, phyllite, and soapstone. Ect..........
What are 2 examples of Igneous rocks?
granite, basalt, pumice, obsidian, rhyolite, diorite, andesite, gabbro, scoria, tuff, pegmatite, peridotite, dunite, and syenite. Ect..........
What is clastic rocks?
Sedimentary rocks that are made up of broken pieces of minerals and rock fragments.
What is deposition?
The laying down or settling of eroded material.
How are Sedimentary rocks formed?
When small pieces of existing rocks, minerals, or organic matter accumulate on the Earth's surface, are buried deep down, and then become compacted and cemented together through a process called lithification, essentially turning to stone.
How are Metamorphic rocks formed?
When rocks are exposed to extreme temperatures and pressure, such as along plate boundaries,they can change to Metamorphic rocks. In addition chemical fluids can cause rocks to become Metamorphic rocks. They can form from any igneous or Sedimentary rock or even another Metamorphic rock.
How are Igneous rocks formed?
When magma or lava cools and crystallizes, it creates Igneous rock. As mineral crystals grow, they connect. These crystals become the grain in an Igneous rock.
What is regional metamorphism?
It's the formation of Metamorphic rock boobies that are hundreds of square kilometers in size.
