a great cloud of Gas and dust began to collapse of gravitational pull.

the solar systm was formed into bodies with hearly circulate or bits beacause of the whirpool *geocentric model *heliocentric model

13.8 billion years ago with a massive expansion. it started from a single point

he said that universe started with a single point

study of the universe

its includes planet, moons, minor planets, stars, galaxies, space, matter and energy

billion of the star and thier solar system , all held together by gravity

noticed that other galaxies were moving away from each other

biblical creation

planets were formed by the collision of the sun with a giant comet, foremd and rotate in the same directions as they revolved arround the sun.

period od expansion and constraction

star paased near the sun it pulled out materials due to gravitational attraction, that was turn out of the sun

4 planets are much larger than the inner planets

4 planets close to the sun

*located in the habitable zone

protect the earth from meteriods and asteriods. protect the earth from the uv radiation from the sun.

allows the accurence of volcanic eruption and earthquake. allows the renewal, fromation or disappearance of land forms.

earth is the only place where life forms exist. bacteria, arehea, fungi, protist, plants and animals.

allows life to exist.

solar winds can break the ozone layer.

also called as geosience. it is the study or the earth's characteristics and bahavior

the earth gets energy or heat from the sun but it returns only some energy back to space.

mercury, venus, earth, mars

jupiter, saturn, uranus, neptune

it is acycle that explains the continous movement of the water above or below agent of this cycle.

the sun is the major driving force of this process for it will heat the water and it will become water vapor. it involves the molecular change of water from liquid to gas.

the sun obsorbs the water from the arial part of the plant and it will evaporate and become water vapor.

it is happening when the evaporated water vapor cooled down to its dew point. it is usually when the clouds re formed.

it is a primary connection int the water cycle that provides for the delivery of the atmospheric water to the earth.

types of precipitation

its the process by which precipitation was observed by the soil and moves into the rocks and usually replenishes the groundwater system

it is solid state of the earth it includes the structure, composition, minerals and processes of earth.

its part of geosphere that is composed of the solid, outermost part of the planet

part of the earth, layers of the earth

it is most important subsytem an earth it is totality of all the ecosystem in the whole earth

it is a most outer layer of the earth it is a solid mode of rock it is e thinnest layer of the earth it is arround 30 kilometres thick

it is a second outer layer of the earth it is a 3000 km thick it is a really thick liquid layer mode it is next to the outer core

it is a third most outer layer of the earth it is a liquid layer made of mollen iron and nickel it is 2,266 km thick

it is centre layer of the earth it is solid layer made of nickel and iron it is 250- 490 km thick it is the hottest layer of the earth

are formed from wolten rock called magma. usually very hard to break

types of igneous rock from when molten erupt from earth interior through a volcanic vent or fissure and cool rapidly of the surface ex. basalt

it is the type or rocks from form solidfield magma below the surface of the earth ex.granite

it is a types igneous rocks are formed sedment grains deposited by water, wind or ice they are always fromed in layers, called beds or strata and quite often contains fossils. ex.sands tone, limestone.

it is a type or rock that were once igneous rocks , but have been changed as a result of intense heat and/or pressure within a earth's crush ex.state marble

formation Planets

5 hydrological cycle (water cycle)

galaxies are not moving away from each other no expansion and constraction everything is the same

it is the liquid component of the earth help the atmosphere to become uts current state covers 70% of the earth surface 98% of the water on earth saltwater

layer of the atmosphere

materials meet a five reqirements

the scientific study of the rocks

a person who specialized in petrology

the study of the chemistry, crystal, structure and physical properties of the mineral constituents of rocks

a person who studies the formation, occurence properties, composition and classification of minerals

uniques properties od minerals

refers to the quality and intensity of light reflected from a mineral surface high luster mean high reflective.

caused by the obsorption of lack thereat of visible light by the bonds on the structure

a color of the powder materials when you rub the minerals of a unglazed porcelain place.

descibes how a crystal breaks when shbjects to stress on a particular plane.

define as the minerals ability to resist scratching or obrasion

is used as convinient way to help identify minerals.
