18
Replication occurs when
Other scientists steal your data
Other scientists repeat your experiment and have the same results

You get gremlins wet
19
What Is Deposition?
The act of sediment being carried someplace else by erosion

The laying down of sediment carried by erosion
20
What is an independent variable?
Something that you, as the scientist, changes
Something your 35 year old cousin will never be
A show on Netflix
The variable that reacts to the change
21
Why do scientists communicate?
They communicate to plan a celebration.
They communicate to check each other's work and share expertise.
They communicate to sabotage each other's work.
They communicate to have fun.
22
What is the Law of Superposition?
The idea behind radiometric dating and determining absolute age
Rocks are divided into strata when determining age
Rocks that are older are found closer to Earth's surface
Rocks that are older are found deeper in the Earth
23
What is a dependent variable?
The thing that stays the same
The leftovers from last night
The variable that reacts to the change
The variable that you change
24

All of the above
Life
26
What happens at a convergent boundary?
Tectonic plates move past eachother
Seafloor Spreading
Tectonic plates move apart
Tectonic plates move toward eachother
27
Describe when scientific knowledge was gained even though a hypothesis was not supported.
Shows that all hypotheses are wrong
It proves you have no idea what you're doing
What even is scientific knowledge?
Examining data can lead to a new hypothesis
28
How are deltas formed?
Connection of channels
Creation of large, flat areas by flooding deposits

29
What is true about all models?
