An educated guess based on prior knowledge, observation, or research that can be tested.
What is an "Hypothesis"?
100
Rocks that are formed by layers and layers of sediment bonded together by minerals - not heat.
What is "Sedimentary Rocks"?
100
The smallest building block.
What is an Atom?
100
Theory that states that the Earth's crust and upper mantle are broken into plates, which are huge rock slabs that move in different directions and at different rates over the Earth's surface.
What is the "Theory of Plate Tectonics"
100
Solid, liquid, and gas (vapor).
What are the Three Forms of Matter?
200
The factor that changes as a result of changes in other variables.
What is dependent variable?
200
This type rock is formed from magma that may be cooled in different ways in different places.
What is "Igneous Rocks"?
200
The positively charged center of an atom that contains protons and neutrons and is surrounded by a cloud of electrons.
What is The Nucleus?
200
A broad volcano with gently sloping sides built by NON-EXPLOSIVE eruptions of basaltic lava that accumulates in layers.
What is a "Shield Volcano"?
200
A natural underground body of water.
What is an "Aquifer"?
300
A factor that, as it changes, affects the measure of another variable.
What is independent variable?
300
Rocks in which the structure, texture, or composition of the rock have changed because of heat, pressure, or a combination of both.
What is "Metamorphic Rock"?
300
Positively charged particles inside the nucleus of the atom.
What is the Proton?
300
A steep-sided, generally small volcano that is built by the accumulation of tephra (ash, lava that has shot high in the air and fallen) around the vent. These are more explosive that "Shield Volcanoes".
What is a "Cinder-cone volcano"?
300
The process by which rocks on or near Earth's surface break down and change.
What is "Weathering"?
400
The amount of matter in an object.
What is "Mass"?
400
The series of processes in which a rock forms, changes from one type to another, is destroyed, and forms again by geological processes.
What is "The Rock Cycle"?
400
A neutral particle inside the nucleus of an atom.
What is a Neutron?
400
A large, sloping volcano built by VIOLENT eruptions of volcanic fragments and lava that accumulate in alternating layers.
What is a "Composite Volcano"?
400
When the precipitation falls on land and enters the ground through infiltration.
What is "Groundwater"?
500
The standard used for comparison of test results in an experiment.
What is "Control"?
500
This is the type of rock formation in which fossils most likely occur.
What is Sedimentary Rock?
500
Particles surrounding the center of an atom that have a charge of 1-.
What is an Electron?
500
Precipitation that falls to the Earth's surface and keeps moving.
