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 made of)
solid
a state of matter that maintains its own shape instead of conforming to the shape of the container.
liquid
something that can f;ow and takes the shape of its container, like water or juice, but it has fixed the 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 rocks
hardness
How easily or difficult it is to scratch a minerals surface.
streak
the color of its powder when you rub it in a hard, rough surface like a tile.
tiles
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 some colors of light and reflect the rest.
luster
how shiny a rock or mineral looks when light shines on it, like a mirror, or glassy, or even dull. (luster is a physical property used by mineralogists to help identify minerals.)
cleavage
How some minerals break a long 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 your fingernail or,a penny) to see if its hard or soft.
