The impression of an organism in a rock usually of the hard parts such as shells and bones; sediment forms around these parts.

A mold that becomes filled with sediment that hardens.

The preserved evidence of the activity of an organism. It could be footprints; information such as speed and weight can also be estimated

Atoms of the same element that have different number of neutrons.

Occurs when the last individual organism of a species dies.

The change over time in populations of related organisms.

A person who studies plants and animals by observing them in their natural environment.

A slight difference in an inherited trait of individual members of a species. They occur in the offspring as a result of sexual reproduction or random mutations can lead to changes to phenotypes.

The process by which populations or organisms with variations that help them survive in their environments live longer, compete better, and reproduce more than those that do or have the variations.

An inherited trait that increases an organism’s chance of surviving and reproducing in its environment.

The study of chemical processes in living organisms; think internal body systems functionality.

An adaptation that enables a species to blend in with its environment.

The resemblance of one species to another species that help prevent the organism from being eaten.

The breeding of organisms for desired characteristics. (Hint: this is usually done by farmers and scientists.)

The study of similarities and differences among structures of living species.

Body parts of organisms that are similar in structure and position but different in function.

Body parts that perform similar functions but differ in structure.

Body parts that have lost their original function through evolution.

The science of the development of embryos from fertilization to birth.

The study of gene structure and function.

A solid that is naturally occurring, inorganic, and has a crystal structure, and definite chemical composition.

Atoms arranged in an orderly, repeating pattern.

The process by which atoms form a solid. It can happen in two ways.

The color of a mineral’s powder.

Describes the way that a mineral’s surface reflects light.

The descriptive way a mineral can break. Here the mineral breaks smoothly and is usually flat after the breakage.

When the mineral breaks rough or irregular.

Deposits of metallic or nonmetallic material that can be produced at a profit.

A quality or characteristic of an individual or thing.

A measure of how easily a mineral is scratched.

A naturally occurring solid mixture composed of minerals, smaller rock fragments, organic matter, or glass.

Individual particles in a rock.

Molten rock inside the Earth.

Molten rock that erupts onto earth’s surface.

Used to reference grain size and how the grains are arranged in rocks.

The source material for most sedimentary rocks.

The process through which sediment turns into rocks.

When pressure causes flat minerals to line up, giving the rock a layered appearance

The series of processes that continually change one rock type into another.

When lava cools and crystallizes on Earth’s surface.

When magma cools and crystallizes inside Earth.

The process that moves large amounts of rock up to Earth’s surface and to higher elevations. It's usually driven by Earth’s tectonic activity and often associated with mountain building.

The resulting activities or glaciers, wind and rain that causes rock to break down.

The process of carrying sediment to low lying areas.

A low lying area.

The process of laying down sediment in a new location. Also, the forming of sedimentary layering over time.

The weight of overlying layers which causes layers to pack in.

When minerals in the pores of sedimentary rock dissolve and crystallize grains together.

Rocks subject to high temperature and pressure changes.

Preserved remains or evidence of ancient living things.

The idea that conditions and organisms on Earth change in quick, violent events.

States that geologic processes that occur today are similar to those that have occurred in the past.

The fossilized carbon outline of an organism or part of an organism.

A scientist who studies fossils.

The age of rocks and geologic features compared with other rocks and features nearby

The principle that in undisturbed rock layers, the oldest rocks are on the bottom.

A piece of an older rock that becomes part of a new rock.

A surface where rock has eroded away, producing a break, or a gap, in the rock record.

Matching rocks and fossils from separate locations.

Represent species that existed on Earth for a short length of time, were abundant, and inhabited many locations.

The numerical age, in years, of a rock or object.

Atoms of the same element that have different numbers of neutrons.

The process by which an unstable element naturally changes into another element that is stable.

The time required for half of the parent isotopes to decay into daughter isotopes.

A type of reproduction in which the genetic materials from two different cells combine, producing an offspring.

The new cell that forms from fertilization.

Cells that have pairs of chromosomes.

Pairs of chromosomes that have genes for the same traits

arranged in the same order.

Cells that have only one chromosome from each pair.

One diploid cell divides and makes four haploid sex cells and only occurs in the formation of sex cells.

One parent organism produces offspring without meiosis and fertilization.
