Earth's system Flashcards
physical properties
any property that can be observed using the five senses
or can be measured without
changing the matter.
weight/mass
weight-how heavy an object is
mass is how much stuff matter
something it is made of.
solid
a state of matter that maintains
its own shape instead of conforming to the shape of its
container.
liquid
something that can flow and takes the shape of its container
like water or juice but it has fixed amount of space volume similar to how a solid stays the same size.
conduct
it allows something like heat
or electricity to flow or pass
through it easily.
heat
energy that moves from something hot to something cold, a form of energy.
minerals
a substance found in nature, minerals make up rock
hardness
how easy or difficult it is to scratch a minerals surface
streak
the color of its powder when you rub it on a hard rough surface like tile
tiles
the colored powder left behind when a mineral is scraped across a hard surface like ceramic tile, which helps identify the mineral by its streak color.
color
its what light reflects back to our eyes. minerals are colored because they absorb some colors of light and reflect the rest.
luster
how shiny a rock or mineral looks like when light shines on it.
cleavage
how some minerals break along smooth, instead of random like when you crack an egg
scratch test
where you try to scratch a rock with different objects
rocks
a natural formed combination of minerals and other natural materials
minerals
a naturally formed substance that always has the same composition and the same properties
sediment
the dirt and stuff that settles to the bottom of liquids
sedimentary
rock formed from compacted sediment
igneous
rock formed from magma or lava
metamorphic
rock formed from existing rock, heat and pressure cause the minerals to form new combinations or new crystals
