Intro to Earth Science
Density/Earth Structure
Soil
Minerals/Rocks
Plate Tectonics
100
A process involving these steps: research question, hypothesis, observations/data, analysis/interpretations, conclusion
What is the Scientific Method?
100
The formula for density
What is density = mass / volume ?
100
Soil macronutrients important for plant growth
What is Nitrogen (N), Phosphorus (P), and Potassium (K)?
100
The number of protons in an atom
What is the atomic number?
100
the first person to propose the theory of continental drift
Who is Alfred Wegener?
200
An experiment in which all variable factors have been kept constant, apart from the independent variable.
What is a controlled experiment?
200
The only way to change the density of a pure substance
What is change the temperature?
200
Based on the image, this horizon is most similar to the original parent material of the soil.
What is the C Horizon?
200
This layer of earth is composed of rocks and minerals
What is the lithosphere?
200
A fault line caused by compressional stress
What is a reverse fault?
300
The variable that is manipulated or changed.
What is the independent variable?
300
Mantle convection occurs because of this
What is heat from the core?
300
This describes how easily water can infiltrate and pass through soil
What is permeability?
300
A physical property that describes how light reflects off a mineral's surface
What is luster?
300
These volcanoes form typically at subduction zones, like the west coast of the United States.
What are composite (stratovolcano) volcanoes?
400
We have these due to Earth being tilted on it's axis at 23.50
What are seasons?
400
This state of matter has the most densely packed particles
What is a solid?
400
The four primary components of soil
What is minerals, air, water, and organic matter?
400
Pre-existing rock that has been altered by heat and/or pressure
What is metamorphic?
400
These mountains form due to tensional stress and can be viewed in the Sierra Nevada Mountain Range. 
What are fault block mountains?
500
The four spheres of earth
What is atmosphere, hydrosphere, biosphere, and geosphere?
500
This would be the result of oceanic and continental crust colliding
What is subduction?
500
This soil horizon that is most important for productivity
What is the A-horizon because it is a blend of organic matter and minerals?
500
light colored igneous rocks containing large amounts of feldspar and silica
What is felsic?
500
The youngest rocks on the ocean floor are typically found here.
What is a mid-ocean ridge?
