Climate and Groundwater
What type of soil allows more water to flow in?
Unsaturated soil
The physical and chemical breakdown of rocks near Earths surface
Weathering
Determines the color of a minerals powder
Streak
Which is denser: Oceanic crust or continental crust?
Oceanic crust
This rule states that the lowest layer in a rock sequence was formed first and is the oldest.
Superposition
The rate at which water enters the ground
Permeability
What type of climate erodes sediments by wind?
Arid climates (desert) or along shorelines
When a mineral breaks with at least one flat surface it is considered...
Cleavage
When one plate slides past another plate
Transform boundaries
Why are index fossils and volcanic ash layers good time markers?
They occur over a wide area in a short period of time
Upward movement of water between small particles
Capillarity
U-shaped valleys, parallel scratches, and groves in bedrock indicate a rock was eroded by a...

This type of rock bubbles with acid
Limestone, marble, or dolostone
Mid-ocean ridges are typically formed by this plate boundary
Divergent boundaries
What radioactive isotope could date the fossil Mastodont?
Carbon-14
The side of the mountain where it is cool and humid
Windward
What process makes sediments rounder as they are transported through streams?
Abrasion
You can determine this type of rock if you see foliation
Metamorphic rock
Locations away from plate boundaries where volcanic activity occurs
Hot spots

Where does deposition occur in a river?
Hint: A river with curves
Inside of a stream curve
What affects the color and density of igneous rocks?
Mineral composition (mafic, felsic)
