Earth Space Elements
anything that has mass and
takes up space.
a substance that
be separated or broken.
smallest unit of
that can exist by itself & retain all chemical properties.
describe how a substance changes into a new substance by combining or breaking apart.
shows how many atoms of each are in a unit of a substance.
characteristics that can be observed without changing the identity of the substance.
change that occurs when one or more substances change into a new substance with different properties.
properties without changing identity of the substance
unit of an element
that maintains the chemical properties of the element
can be separated by
vibrate around fixed positions.
particles close together.
Because they are all in
, all particles of matter have
solid -> gas
gas -> liquid
liquid -> gas
solid -> gas
in the nucleus
in the nucleus
positive, lose electrons
negative, gain electrons
positively charged metal ions
and the electrons around them.
Terrestrial; few or no moons; Mercury -> Mars
Gaseous; large, rings, many satellites; Jupiter -> Neptune
Solar system was formed from a cloud of
small body of
that follows an
meteoroid that is falling through earths atmosphere.
meteoroid that survives fall to earth.
smaller than asteroids; found out in space
small solar system bodies that orbit the Sun.
distance light travels in a year.
sphere shape with arms
sphere shape, no arms
no definite shape.
object so massive & dense not even light can escape its gravity.
dust & gas located between stars in a galaxy.
planet-like bodies that orbit the Sun
rock that forms when magma cools, solidifies, & crystallizes.
rock that forms from other rocks undergoing extreme heat & pressure.
formed from remains of older rocks; type of rock in which fossils are made.
when a rock is broken down due to
with the environment.
breaks rock down but does
alter chemical composition.
occur along shifting plate boundaries; caused by rocks breaking.
produced by earthquakes.
primary; move faster; originate at focus
secondary; move slowly; originate at focus
move along surface; cause most damage; origin at epicenter.
plates slide over each other.
area where one plate slides over another.
two tectonic plates past one another.
plates slide past one another.
Cinder Cone volcano:
mild eruptions; largest volcano
made of alternating layers of ash, cinders & lava; very steep.
most abundant; violent eruptions
principle of superpostion:
age of rock; older on bottom; newer on top.
uses radioactive isotopes to assign approximate ago to rocks.
have characteristic chemical composition; occur naturally; have orderly internal structure.
found in sedimentary rock; remains of once-living organisms.
removal & transportation of weathered & non-weathered materials.
process in which material is laid down or deposited as a result of erosion.
