Evolution
These preserved remains or traces of ancient organisms are found in rocks and help scientists study the past.
Fossils
This is a term used to describe a trait that helps an organism survive better in it's environment
Adaptation
This type of rock forms when magma cools and hardens.
Igneous
This law states that energy can not be created or destroyed
The Law of Conservation of Energy
This type of pollution occurs when harmful gases enter into the atmosphere.
Air Pollution
This type of rock is most likely to contain fossils because it forms from layers of broken down rocks.
Sedimentary Rocks
This scientist developed the theory of evolution after spending time on the Galapagos islands and studying finches, iguanas, and tortoises.
Charles Darwin
This process breaks down rocks into smaller pieces through wind, water, or ice.
Weathering
This energy is stored in the bonds between molecules as in food, batteries, and fuel.
Chemical Energy
Burning these energy resources (coal, oil, and natural gas) releases large amounts of pollution into the environment. They are a class of resources called:
Fossil Fuels
This type of fossil forms when tree sap surrounds an organism and hardens over time.
Resin Fossil or Amber
This term refers to differences in traits among individuals of the same species.
Variation
This rock forms when a rock is changed my heat and pressure without melting.
Metamorphic
This energy travels in electromagnetic wave. It is the only energy that can pass through a vacuum such as space.
Radiant Energy
This effect happens when gases in Earth's atmosphere trap heat from the sun, keeping the planet warm.
Greenhouse Effect
This principle (or law) states that in undisturbed rock layers, the oldest fossils are found at the bottom.
Law of Superposition
This type of selection occurs when humans choose which plants or animals reproduce, such as breeding dogs for specific traits.
Artificial Selection
These two types of igneous rock are classified based on where the magma cools - above or below ground.
Intrusive and Extrusive
This type of energy is stored in the nucleus of an atom.
Nuclear Energy
This gas, produced by farm animals, is a lesser known, but more potent greenhouse gas.
Methane
Scientists use this method, involving radioactive elements, to determine the absolute age of fossils.
Radiometric Dating (or Carbon Dating)
During the Industrial Revolution, this insect changed from mostly light-colored to mostly dark-colored because darker individuals were better hidden from predators on soot-covered trees.
Peppered Moths
This process occurs when magma cools and minerals form crystals, creating solid rock.
Crystallization
This energy conversion powers the sun.
Nuclear to Radiant and Thermal
This is one of the top three emitters of greenhouse gases.
