Geology and Hydrosphere Flashcards
(47 cards)
Naturally occurring inorganic solids that possess an orderly crystalline structure that can be represented by a chemical formula
Minerals
Consolidated mixture of minerals
Rocks
Formed from cooled magma that solidated through crystallization
Igneous
Large crystal formed from slow cooling of magma below the earth’s surface
Intrusive
Large crystal formed from quick cooling of magma at the earth’s surface
Extrusive
Formed from the lithification of sediments
Sedimentary
Originated as solid particles derived from weathering and are transported
Detrital Sediments
Originated from soluble materials produced by chemical weathering
Chemical Sediments
Rocks are subjected to extreme heat and pressure
Metamorphic
Effects of metamorphism
- increased density
- recrystallization
- Reorientation of mineral grains
- formation of new minerals
The hypothesis that breaking apart of a super Continental into smaller continents, then drifting into their current positions
Continental drift
Proposed the continental drift theory
Alfred Wegener
Provides the mechanism for the continental drift hypothesis
Plate tectonic
Outer solid layer of the earth
Lithosphere
Lithosphere is divided into segments called
Plates
Weaker inner liquid layer of the earth
Asthenosphere
Rapid vibration of earth due to the release os energy that were subjected to extreme pressure
Earthquake
Plates that moves apart
Divergent boundary
Plates that grind against each other
Transform boundary
Plates that moves toward each other
Convergent boundary
Types of pyroclastic material by size
Ash/Dust -> Lapili/Cider -> Block -> bomb
Symmetrical cones with structure of imbedded lava and pyroclastic material
Composite volcano
Have steep slopes composed of pyroclastic materials
Cider cone volcano
Broad, domed volcanoes composed of basaltic lava
Shield Volcano
