Rocks and Weathering Flashcards
is the formation of intrusive igneous rock by solidification of magma beneath the earth’s surface.
Plutonism
What are the types of rocks?
- ) Igneous
- ) Sedimentary
- ) Metamorphic
this type of rock is formed by the cooling of molten magma on the earth’s surface.
Igneous Rocks
are rocks found in magma.
Intrusive/Plutonic Rocks
are rocks formed from magma.
Extrusive/Volcano Rocks
are rocks came from erupted matters.
Pyroclastic Rocks
is the molten rock material that originates under the earth’s crust and forms igneous rock when it has cooled.
Lava
are rocks formed through weathering and erosion igneous and metamorphic rocks under the process of compaction.
Sedimentary Rocks
is the action of weathering to change object physically and chemically.
Weathering
a type of weathering in which occur when large rocks are broken into smaller fragments without changing its composition.
Physical or Mechanical Weathering
a type of weathering that is the chemical change of rocks.
Chemical Weatehring
a type of weathering that includes all living things.
Biotic Weathering
What are the three types of Weathering?
- ) Physical
- ) Chemical
- ) Biotic
what are the three types of Physical Weathering?
- ) Block disintegration
- ) Exfoliation
- ) Frost Action
is the successive heating and cooling of rocks. If hot it’ll expand and when it’s cold, it’ll shrink.
Block disintegration
is the peeling off of the outer layer rocks. Due to intense heating.
Exfoliation
is the alternate freezing and melting of water in the joints of rocks.
Frost Action
What are the four type of Chemical Weathering?
- ) Oxidation
- ) Hydration
- ) Solution
- ) Carbonation
oxygen reacts on ferrous material found in rocks producing oxide.
Oxidation
is the absorption of water. Volume will increase then it will lose its shape.
Hydration
the minerals in rocks dissolved in water.
Solution
formation of carbonates.
ex. Carbon Dioxide reacts on limestone then produces carbonic acid.
Carbonation
What are the eight types of Biotic Waethering?
- ) plant roots
- ) Burrowing
- ) Human Being
- Erosion
- ) Lithification
- ) Metamorphic
- ) Aphanite
- ) Phanerite
are penetrarting into the joints of rocks.
Plant Roots
means digging
ex. ants, termites, rats, rabbits, and earthworms
Burrowing
by doing activities like agriculture, construction of houses and roads, and quarry.
Human Being
is the destruction made by nature forces. Transportation from one place to another by the means of water, wind, and ice.
Erosion
is a process of porosity destruction through compaction and cementation.
Lithification
are the result of extreme heat and pressure. Formed below the earth surface due to movements of plates. Also formed by collision of plates.
Metamorphic rocks
is a fine-grained igneous rock having such compact texture that the constituent minerals cannot be detected with the naked eye.
Aphanite
is an igneous rock whose microstructure is made up of crystals large enough to be distinguished with the unaided eye.
Phanerite
