Earth 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 is made of.)
Solid
a state of matter that maintains it own shape instead of conforming to the shape of the container.
Liquid
something than can flow takes the shape of it’s container, like water or juice , but it has a 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 though it easily.
heat
energy that moves from something hot to something cold, a form of energy.
minerals
A substance in nature, minerals make up rocks.
hardness
how easily or difficult it is to scratch a mineral’s surface.
streak
the color of it’s powder when you rub it on a hard, rough surface like a tile
tile
the colored powder left behind when a mineral is scraped across a hard surface like a ceramic tile, which helps identify the mineral by it’s streak color
color
it’s what light reflects back to our eyes. minerals are colored because they absorb some colors of light and reflects the rest.
luster
how shiny a rock or mineral looks when light shine’s on it, like a mirror,or glassy, or even dull. (Luster is a physical property used by mineralogist to help identify minerals.
cleavage
how some minerals break along smooth, flat lines instead of randomly, like when you crack an egg.
Scratch test
where you try to scratch a rock with different objects (like a fingernail or a penny) to see if it’s hard or soft.
rocks
A naturally formed combination of minerals and other natural materials.
minerals
a solid, 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, or is carried and then deposited by water, wind, or ice.
sedimentary
rock formed from compacted sediment.
igneous
rock formed from magma or lava.
metamorphic
rock formed from
