Anything that has mass and takes up space
What is matter?
These are the preserved remains or traces of living things.
What are fossils?
This is the force that attracts all objects towards each other.
What is gravity?
This is the basic unit of structure and function of all living things.
What are cells?
This is known as a disturbance involving the transfer of energy from place to place.
What is a wave?
This is the study of matter and how it changes.
What is chemistry?
This is what a scientist who studies fossils is known as.
What is a paleontologist?
This is the amount of matter that is in an object.
What is mass?
This is the rigid layer that surrounds the cells of plants and some organisms.
What is a cell wall?
These types of waves require a medium to travel through.
What are mechanical waves?
This is a characteristic of a substance that describes it ability to change into different substances.
What is a chemical property?
This refers to the change in living things over time.
What is evolution?
This is known as the tendency for an object to resist a change in motion.
What is inertia?
This controls what substances can pass into and out of cells.
What is a cell membrane?
The high point of a transverse wave is known as this.
What is a crest?
This is a characteristic of a substance that can be observed without changing into into another substance.
What is a physical property?
This is what a rock's age compared to other rocks is known as.
What is its relative age?
This is known as an object that orbits a star, is large enough to have become rounded by its own gravity, and has cleared the area of its orbit.

What is the nucleus?
The low point of a transverse wave is known as this.
What is a trough?
This is made of two or more substances that are together in the same place, but their atoms have not chemically bonded.
What is a mixture?
This law states that in undisturbed sedimentary rock, the oldest layer is at the bottom, and the youngest layer is at the top.
What is the law of superposition?
This is a unit of distance equal to the average distance between Earth and the sun. (about 150 million km)
What is an astronomical unit?
This substance fills the region between the cell membrane and nucleus.
What is cytoplasm?
The units that measure frequency.
