Geologic Time Scale

250

This is the theory that suggests that Earth's continents sit on plates that are constantly in motion.

Plate Tectonic Theory

250

This is the underground substance igneous rock forms from.

Magma

250

Minerals have several important physical properties. This property is the least effective to use when trying to identify a mineral.

Color

500

In the immediate aftermath of the Big Bang, this process began causing the universe to expand.

Inflation

500

This is the process by which gravity allows larger objects to absorb the material of smaller objects.

Accretion

500

This is the main element that makes up the sun.

Hydrogen

500

This step of Earth's formation created the core, mantle, and crust by separating heavier elements from lighter ones.

Differentiation

500

This is the process used to arrange events in an order that uses exact numeric values.

Absolute Dating

500

Plates that interact by moving toward each other have this type of boundary.

Convergent

500

This geologic feature is where most visible igneous rock is formed.

Volcano

500

This is a minerals resistance to external force.

Hardness

750

The universe's size is currently doing this.

Expanding

750

This is the process by which objects form in an accretion disk.

Condensation

750

This is the process that combines hydrogen into helium.

Nuclear Fusion

750

This stage of Earth's formation brought the first drops of water to the planet.

Cratering

750

This is the process of creating a general order of events.

Relative Dating

750

Plates that move away from one another interact at this boundary type.

Divergent

750

This type of rock is formed from the breakdown of other existing rock.

Sedimentary Rock

750

This property describes how a mineral reacts to light.

Luster

1000

This is the "echo" of energy left behind after the Big Bang.

CMB (Cosmic Microwave Background)

1000

This is a swirling collection of dust and gas that will eventually become a solar system.

Accretion Disk

1000

This is the process that moves energy from the sun's core to the photosphere.

Convection

1000

This stage of Earth's formation helped to create both the atmosphere and the oceans.

Flooding

1000

This technique of dating organic material is only effective up to about 50,000 years.

Carbon-14 Dating

1000

Earthquakes happen primarily at this type of boundary.

Transform

1000

This type of rock is made by adding heat and pressure to pre-existing rock.

Metamorphic Rock

1000

This property is the more effective way to identify a mineral's color.

Streak

1250

Jim Parsons, Kalee Cuoco, and Johnny Galecki star in this CBS comedy that ran for 12 seasons.

The Big Bang Theory

1250

This is what forms at the center of an accretion disk.

A star

1250

These are the two forms of energy the sun releases.

Radiation and heat

1250

This is the most used source of evidence for the age of the Earth.

Meteorites

1250

This is an event that marks a drastic decline in the population of living things on Earth.

Mass Extinction Event
1250

This is the name of the large singular landmass that was once made up by all of the continents.

Pangaea

1250

This type of rock is created from magma or lava.

Igneous Rock

1250

This is the name of a mineral that has been cleaned, polished, and cut into a specific shape.

Gemstone

1500

This is the term, coined by Edwin Hubble, to show how objects are moving away from each other.

Red Shift

1500

This is the term given to the set of stars and planets that form from an accretion disk.

Solar System

1500

This is a massive release of solar energy that can cause damage to natural and man-made systems on Earth.

Solar Flare or CME (Coronal Mass Ejection)

1500

This is the name given to the planetary object that is believed to have struck the Earth and helped to create the Moon.

Theia

1500

This is the study of the different layers of rock.

Stratigraphy

1500

This is the theory supported by the creation of new ocean floor.

Seafloor Spreading
