Remains, traces, or imprints of once living organisms preserved in sedimentary rock.
What are fossils?
100
Always written as an if...then statement
What is a Hypothesis?
100
He proposed the theory of continental drift
Who is Alfred Wegener
100
This is the process that continually adds new material to the ocean floor
What is sea-floor spreading
100
The heat source which creates convection currents in the mantle.
What is the core?
200
Abundant and widespread are characteristics of these types of fossils
What are index fossils
200
Measurements used around the world, have a base of ten.
What are SI units?
200
These three types of evidence helped support the theory of Continental Drift
What is evidence from land features (landforms), from fossils, and climate
200
This is what erupts through the valley of the mid-ocean ridge
What is molten material / lava
200
Earth's lithosphere is broken into separate sections called
What are plates
300
The time it takes for 1/2 of the parent element to become stable daughter element.
What is the half life?
300
Information gathered using one or more of your five senses
What is an observation?
300
Scientists who study the forces that make and shape the planet Earth are called
Who are geologists
300
This is the process by which scientist were able to map the ocean floor and discover the mid ocean ridge
What is sonar/ sound waves
300
This type of boundary is a place where two plates slip past each other
What is a transform boundary
400
The scale used by geologist to record events in Earth's history
What is the geologic time scale?
400
The part of the experiment that you establish the limits on; it is graphed on the X axis.
What is the independent variable?
400
Fossils of tropical plants found on an island in the Arctic Ocean are evidence for Wegener's hypothesis of
What is Continental Drift
400
These are the types of evidence that support the theory of sea floor spreading
What are magnetic stripes in the rock of the ocean floor (pattern of rocks), and the age of rocks from drilling samples.
400
The theory states that pieces of Earth's lithosphere are in slow, constant motion, driven by convection currents in the mantle. This theory explains the movement, formation, and subduction of Earth's plates.
What is the theory of Plate Tectonics
500
The matching of rocks based on fossils or composition
What is rock correlation?
500
The most important thing when conducting a scientific investigation. Way more important than getting the right answer. If you don't have this then you should redo the experiment.
What is accuracy?
500
The reason scientists rejected Wegener's theory was because he could not do the following
What is explain what force pushed or pulled the continents
500
Iceland is a part of this chain of volcanoes that is pushing the continents of North America and Eurasia further apart.
What is the mid Atlantic Ridge?
500
These are the three kinds of plate boundaries
What are spreading boundaries (divergent), colliding boundaries (convergent), and sliding boundaries (transform)
