Solar System Formation – Earth Formation Layers of the Earth Review

The force of attraction between two objects

Accretion solar windgravity

The clumping together of smaller gas and dust particles into larger objects

AccretionSolar windGravity

A stream of charged particles from a star

AccretionGravitySolar wind

Nebula formed from a supernova and contains heavier elements

Terrestrial NebulaGaseous NebulaSolar Nebula

Earth-like planets made of heavier elements and compounds located closer to the sun

Terrestrial PlanetsGaseous PlanetsSolar planets

Planets consisting of lighter elements located further from the Sun

Terrestrial planets Gaseous planetsSolar planets

Mineral compounds made of silicon and oxygen that make up most of the inner planets crust

CarbonatesSilicatesoxides

Left over frozen gaseous debris where dwarf planets are found

Kuiper BeltOort cloudAsteroid belt

Outer boundaries of the Solar System where comets form

Kuiper BeltOort cloudAsteroid Belt

Region between Mars and Jupiter containing irregular shaped objects

A. THE CRUSTB. THE MANTLE

C. THE INNER CORED. THE OUTER CORE

Ocean Crust is made of

GraniteBasaltOxygenSilicate

Continental Crust is made of

GraniteBasaltOxygenBasalt

Which is more dense?

ocean crust continental crustBoth are the same

Inner planets are _____ than outer planets

A. Less dense, refractory and hotterB. More dense, volatile and coolerC. More dense, refractory and hotterD. Less dense, refractory and hotter

Solar winds caused

A. Less dense material to be blown fartherB. More dense material to be blown farther

Inner planets have

Cores of silicate rock and iron/nickel crustCores of granite and silicate rock crustCores of iron/nickel and silicate rock crust

Outer Planets have

Cores of silicate rock and crust of silicatesCores of gases and layers of graniteCores of silicate and layers of gases

True or False

The asteroid belt lies between Mars and Saturn

The Oort cloud is close to NeptuneThe Kuiper Belt contains Dwarf planetsThe Kuiper Belt is closest to NeptuneComets originate from the Oort Cloud

The iron catastrophe was responsible for

Forming volcanoesForming the coreForming water on the surface

Which Planets were formed by gravity

Inner planetsOuter planets

Which planets are cooler / lower melting points?

Inner PlanetsOuter Planets

Order of Earth Formation first 5 events

Solar nebular, accretion, bombardment, iron catastrophe & radioactive elements

Solar nebula, accretion, bombardment, radioactive elements & iron catastrophe

Solar nebula, bombardment, accretion, iron catastrophe & radioactive elements

Order of Earth formation, last 5 events

Crust forms/ surface water, magnetic field forms, planetesimal hits earth, volcanoes form, moon moves away.

Magnetic field forms, volcanoes form, planetesimal hits earth, moon moves away & crust forms /surface water

Magnetic field forms, planetesimal hits earth, volcanoes form, moon moves away, crust forms/surface water

Minerals – T or F

Man-madeOrganicCan be solid or liquidDefinite crystal structureDefinite chemical composition

The greatest percentage class of minerals in the crust is

OxidesCarbonatesSilicates

Rock formed from magma

IgneousMetamorphicSedimentary

Rock formed from the layering and cementing of sediments over time

Igneous MetamorphicSedimentary

Any rock type that undergoes great pressure and heat

Igneous MetamorphicSedimentary

How can rocks change over time?

Discussion

How do rocks recycle – why do we call how rocks form the rock cycle?
