Earth't 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) some 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 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 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’s surface.
streak
the color of it power when you rub it on 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 its streak color.
color
It’s what light reflects back to our eyes. minerals are colored because they absorb some colors of light and reflect the rest.
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 penny) to see if it’s hard or soft
rocks
A naturally formed of minerals and natural materials.
minerals
A solid naturally formed substance that 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 existing rock; heat and pressure cause the minerals to form new combinations or new crystals.
