It is an observation in physical cosmology that galaxies are moving further from earth at speeds proportional to their distance

hubble's law

He is renowned for determining that there are other galaxies in the universe beyond the milky way

edwin powell hubble

Is the shift from wavelengths that is shorter towards longer wavelengths and for

redshift

It's the opposite because it is a shift from longer wavelengths towards shorter wavelengths

blue shift

Hubbles last states that the relationship of the velocities of distance objects in the universe is

directly proportional

Is a chronological model explaining how the universe began it suggests that the universe started its expansion about 13.8 billion years ago based on the latest calculation

big bang theory

The big bang theory suggests that the universe began as a blank and this is a point in the core of a black hole with extremely high temperature in density

singularity

Is the formation of elements such as hydrogen and helium the presence of these elements led to the formation of stars and galaxies

nucleosynthesis

He is considered the first proponent of the big bang theory in 1933 during the british association meeting he explained that the universe originated in an explosive act of a primeval atom or the cosmic egg which was like a huge atomic nucleus

George Henri Joseph Edouard

Was an american astronomer established hubble's law which provided evidence that the universe was not static that expanding in 1923 hubble spotted what he thought was a flaring nova star in the n31 ebola or the andromeda constellation using a hookerWas an american astronomer established hubble's law which provided evidence that the universe was not static that expanding in 1923 hubble spotted what he thought was a flaring nova star in the n31 ebola or the andromeda constellation using a hooker telescope

Edwin Powell Hubble

American astromer studied cosmic radiation in 1964 they discovered that microwaves with wavelengths about 7 cm per percent in space these waves were referred to as cosmic microwave background radiation

Arno Penzias and Robert Willson

It is believed to be the thermal energy released when the ionized gases become neutral particles as the early universe called down this radiation serve as a leftover when the universe was formed the discovery of this cosmic radiation provided strong evidence that the universe began from the sudden expansion of a singularity

cbm radiation

Outer layer of the earth and tennis and comparison to the other three layers made of solid rocks mostly basalt and granite

crust

Older thicker less denser while the other younger thinner denser

continental crust and oceanic crust

Both the cross and the portion of the upper mantle

lithosphere

Directly under the cinema or silica and magnesium it is the largest layer of the earth 1800 or 1.6 km

mantle

Liquid layer primarily composed of iron and nickel lower pressure

outer core

Solid sphere due to the immense pressure pressure is so great that it compresses the iron and nickel into a solid state even though the temperature is extremely high

inner core

This layer gets its name from the weather that is constantly changing and mixing up the gases in this part of our atmosphere

troposphere

Bigyan sa bob the troposphere and extends approximately 31 miles or 50 km high no storms or turbulence here to mix up the air so cold heavy air is at the bottom and warm light is at the top

stratosphere

The highest layer which the gases are all mixed up rather than being layered by their mass has the lowest temperature of all layers called as -90° c and most meteors burned up in the

mesosphere

This layer can reach up to 4,500 fahrenheit the warming is caused by the absorption of ultraviolet light and ultraviolet light and x-ray emitted from the sun

thermosphere

Means outside and is the very edge of our atmosphere the slayer separates the rest of the atmosphere from outer space 6,200 miles or 10,000 km thick primarily composed of hydrogen and helium the lightestElements

exosphere

Is a naturally occurring solid inorganic substance that has a definite chemical composition and crystal structure

mineral

As magma calls element combine is for minerals such as feldspar and horn blend

crystallization from magma

If this water evaporates some of the dissolved substances can react to form minerals

precipitation

A very hot mixture of water and dissolve substances is 100 degrees celsius and 300° c

hydrothermal solutions

Most minerals cannot be identified by color alone many minerals have the same colors

color

Rob a mineral and it leaves a streak of powder strict is the color of the powder by the mineral

streak

Mineral reflects light is called its luster and also can be metallic or not nonmetallic does not have a metallic shine or reflection

luster

It's resistance to being scratched

hardness

Mineral breaks can also be used to identify the mineral if it split smoothly it's cleavage and if it's jag surfaces its fracture

cleavage and fracture
