How old is Earth?

Much closer to the sun than to other stars

A geological processes that adds new rock to the surface of the earth

Ways a mammal can keep warm

All objects fall freely with the same constant acceleration regardless of their mass; empty space

broadest category in the biological taxonomy

A trait that helps an organism survive and reproduce

a mixture of gases that surrounds a planet or moon

There is the force of your foot on the ball, but there is also the same amount of force that the ball puts on your foot. This force is in the exact opposite direction.

All the water at and near the surface of the earth, 97% of which is in oceans

Any object in motion will continue to move in the same direction and speed unless forces act on it

If you kick a ball it will fly forever unless forces act on it

An interaction in which one organism kills another for food

The largest population that an environment can support at any given time.

Two species occupy the same habitat or eat the same food.

All the different populations that live together in an area

A relationship between two organisms of different species where one benefits and the other is harmed

A form of energy caused by the movement of electrons

A relationship between two species in which both species benefit

One species benefits and the other is neither helped or harmed

Deep within the Earth, protects the Earth from harmful solar wind particles. Responsible for the Northern Lights (Aurora Boresells)

Charged particles escape from sun's gravitational pull.

What would be most different about an object on Mars than Earth?

Planets that equal a solid

Planets that make a gas

When a star explodes. Creates almost all heat elements in the world.

The study of space

Star at the center of Earth's solar system.

How the sun shines and produces heat. When lighter elements become heavier.

is much closer to the sun than is to other stars.

Heat comes from sun to earth

Our solar system is part of a bigger star system called? Made up of stars, dust, and gas.

Planet that is most like Earth's size is

mostly made of ice, dust, and gas

light flashing in the sky

if you drop a ball from space it will

light emitted by a star

Planet that orbits closest to Earth. Most likely Earth's size.

Planet that has the shortest days

Terrestrial Planet

Planet with abnormal tilt on axis.

Causes days/times to differ

Burning fossil fuels and volcanic activity causes _____ _____ on earth's atmosphere.

Largest planet furthest from the sun.

How many days does it take Earth to rotate on its axis?

How long does it take the Earth to revolve around the sun?

The moon revolves around the Earth in ?

Makes up 78 percent of Earth's largest quantity of gas) of the Earth's atmosphere.

When the Earth moves between the moon and the sun.

When the moon lines up between Earth and the sun.

The most common element in the universe.

A massive star with a gravitational field so strong that even light cannot escape.

Occurs when particles from the solar wind are trapped in the Earth's magnetic field.

Everything we can directly see and study. It is cracked, split into tectonic plates. The edges of plates go under the ocean, called contintental shelves.

Bottom of oceans, below continental crust

Thicker on land. Contains: Granite.

Thickest layer of Earth (84% of Earth’s volume). Always in motion. Divide into layers based on seismologic properties

Extends from where the Crust ends. Is sticky but

formed from rock (Peridotite)

Extends from Upper Mantle. Made up of Magnesium

The inner and outer core works together as the temps cool down, more of the outer core develops and becomes part of the inner core.

Solid. Temperatures and pressures are extreme. Solid inner core rotates faster within the outer the outer molten core

Solid, 6,000ft below. Made of iron. Low viscosity but certainly not liquid. Malleable. Site of violent convection (transfer of heat by the movement of a fluid (liquid or gas) btwn. areas of different pressure).

Solid, outer part of the Earth’s surface (Crust and Upper Mantle) Includes tectonic plates)

Layer of gases surrounds the Earth. Retained by Earth’s gravitational pull. Where majority of Earth’s nitrogen is found (78%) 21% Oxygen.

Lowest layer of atmosphere, contains weather. Gets colder as you go up. 80% of Earth’s atmosphere.

Temp. gets warmer as you go up. Ozone layer. Protects from UV rays.

Highest layer. Planet’s first line of defense against sun’s rays, meteors, asteroids. End of atmosphere, beginning of space

Very Hot. Has Aurora Borealis.
