In an experiment where scientists are trying to see if sunlight will affect plant height, this is the DEPENDENT variable
Plant's height (plant's growth, size of plants).
The two properties commonly used to identify Minerals are __________ and ____________.
Streak and Hardness
Which type of rock can eventually become any other type of rock?
all of them (igneous, sedimentary, and metamorphic)
This type of weathering often causes potholes to form in streets.

Javier loves to do his homework while listening to music. He believes that he does his homework with more correct answers when he listens to music. His parents believe that listening to music is distracting and causes more incorrect answers. For the first 10 days, Javier and his classmates complete their homework while listening to music. For the next 10 days, Javier and his classmates complete their homework without listening to music. Every day, their teacher records how many correct answers each student has.
IDENTIFY TWO FACTORS THAT MUST BE HELD CONSTANT:
Type of music, type of homework, amount of homework, amount of time given to complete homework, amount of classmates
What is the difference between INTRUSIVE and EXTRUSIVE Igneous rocks?
Intrusive - Formed underneath earth's surface by magma (cools slowly, large crystals).
Extrusive - Formed on earth's surface (cools quickly, small crystals).
If Igneous rock is broken down into smaller pieces and then buried, compacted and cemented, what type of rock will it become?
sedimentary
There are two types of Wind Erosion. Name them.
Deflation and Abrasion
If you find a fossil that is 600 million years old, you can assume that the layer of rock it was found in is also 600 million years old. What do we call it when we estimate the age of a rock layer based on the fossils found inside of it?
Relative Dating.
