This is the process by which heat or electricity is directly transmitted through a substance
What is conduction?
Electromagnetic waves with the shortest wavelengths and highest frequencies
What are gamma rays?
This is the distance between two corresponding parts of a wave
What is wavelength?
This is the part of the electromagnetic spectrum that consists of waves with the lowest frequencies
What are radio waves?
This is the highest point of a transverse wave

This is a form of energy that can travel through space.
What are electromagnetic waves?
Radio waves with the shortest wavelengths and the highest frequencies
What are microwaves?
This is the interaction among two or more waves in which displacements combine to produce a wave with a smaller displacement
What is destructive interference?
These are rocks that form when sediments such as muds, sands, or gravels are compressed by overlying sediments
What are sedimentary rocks?
A scientist who studies fossils?

This is the number of complete wavelengths that pass a point in a given time
What is frequency?
A principle that geologic processes that occurred in the past can be explained by current geologic processes
What is uniformitarianism?
This is a method of determining the age of a fossil by comparing its placement with that of fossils in other layers of rock
What is relative dating?
A person who studies early people and the objects they left behind
What is an archeologist?
This the study of rock layers.
What is stratigraphy?
The process by which minerals replace parts of an organism.
