Igneous Rocks
The type of rock formed when magma or lava solidifies.
Igneous Rock
What happens to temperature and pressure with depth into the Earth?
Both Increase
When rock fragments break off of a rock, without a chemical change in the rock. What type of Weathering is this known as?
Mechanical (Physical) Weathering
The electrons located in the outermost shell of an atom.
An atom which has gained or lost one or more electrons.
Ion
What are the TWO most abundant elements in magma?
Oxygen and Silicon (form silica)
A fluids resistance to change.
Viscosity
The removal and transport of sediment by water, wind, glaciers, or gravity.
Erosion
The role which a species plays in its ecosystem.
Niche
Species with a narrow niche.
Specialist Species.
The type of rock that forms when magma cools within the Earth.
Intrusive Igneous Rock
When rock cools QUICKLY, what type of texture will be produced?
Fine Grained
The process by which sediments are compacted / cemented together to form solid rock.
Lithification
What is observed / measured during an experiment.
Dependent Variable
A mutually beneficial species relationship.
Mutualism
When rock cools SLOWLY, what type of texture is produced?
Coarse Grained w/ large crystals.
Will a magma with a higher viscosity (less runny) have more or less silica?
More silica
This principal states that sedimentary layers are deposited in sequence. Therefore, layers at the bottom are older than those at the top (unless the rock has been turned over).
Superposition
Parasites which live on the body of their host.
Ectoparasite.
Occurs when newly exposed land is colonized by living things (such as after a volcanic eruption).
Primary Succession
This type of magma has a higher concentration of silica than Basaltic Magma.
Rhyolitic Magma
A rock with a "spongy" texture, produced when gas was trapped in the rock.
Vesicular
Rocks with a layer / banded appearance due to the alignment of minerals under pressure.
Foliated
States that two species that use a limiting resource the same way cannot coexist indefinitely.
Competitive Exclusion Principle
Occurs when species competing for similar resources evolve specialized traits which allow them to share resources in different ways.
Resource Partitioning
