-ATOMIC UNIVERS- universe was composed of very small indivisible and indestructible atoms

STATIC, STEADY-STATE Infinite universe matter on a large scale is uniformally distributed and the universe is gravitationally balanced but essentially unstable assume that

the space was not empty at all but filled with matter that swirled around in large and small vertices his model involved a system of a huge swirling whirlpool of fine matter. CARTESIAN VIRTEX MODEL

assumed that the universe was no different from newton that the universe was static dynamically stable universe which neither expanding nor contracting he would later abandon this theory when in 1929

multiverse, universes like bubble

Aristotle's and ptolemy's universe

believed in geocentric model of solar system no

nicolaus copernicus

he proved the copernican theory using a new invention the telescope was able to view parts of our solar system in motion

the orbit of a planet is an eclipse with the sun at one focus

when a planet is near the sun in its orbit (perihelion) it move faster when it's farther from the sun(aphelion) it moves slower

the largest a planet's orbit the longer it takes

a rogue star pass close to the sun and stripped materials from both the sun and the rogue starprot

the entire solar system started as a large cloud of gas that contracted to to self gravity

build on the main concepts of the nebular hypothesis of fluids and state of matter

he is the belgian priest to whom the bigbang theory is attributed

incorporated cosmic inflation to solve uncertainties of the big bang model

influence how quickly atoms molecules ot organism to move

slow down a chemical reaction causes bound to break

can cause breakdown of biomolecules

absence of this will interfere reaction is a sorry for life

provides insulation or shielding from the sun and meteorites

used to build in maintain organism structure water carbon and oxygen phosphate and nitrogen cycles

living thing and non-living things. system is a set of interconnected components that are interacting to form a unified whole

process that move matter and energy from one sphear to another

solid part of the earth

outermost layer light and very thin outer skin of the earth

less dense layer made up of iron magnesium oxygen and silicon

denser layered earth magnetic field outer core is liquid or molten inner core is solid form nickel and iron has the same temperature of the sun zone of earth where all form of life exists the large ecosystem each organism play an important role in food web

solid form liquid form and gas vapor

zone of earth where all forms of life exist the large ecosystem

then says part almost all weather types are in region

location of ozone layer which absorb the scatter the solar uv radiation

meteors usually burn up and become a shooting star

radio communication possible

it is the area of aurora and satellites

upper limit of the atmosphere separating earth and space

oxygen produced by rainforest

oxygen produced by marine plants

oxygen produced by other sources

naturally occurring
inorganic
solid
definite chemical composition ordered internal structure

minerals of definite chemical composition they form definite structure

the outward appearance of the mineral crystal form

tendency of a mineral to break along planes of weakness

minerals that do not have cleavage full fracture either in irregular mother of conchoidal

the appearance of light as it is reflected off its surface

most obvious minerals property but not reliable in identifying minerals

the color of a mineral it is powdered

measurement of the strength of the chemical bonds in its structure
