Earths system Flashcards
physical properties
any property that can be observed using our 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 its own shape instead of conforming to the shape of its container
solid
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
liquid
conduct
It allows something like heat or electricity to flow or pass through 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 on a hard , rough surface like a tile.
tiles
the colored powered left behind when a minerals is scraped across a hard surface like a ceramic tile , which helps identify
Color
its 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 minerals looks when light shines 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 a long smooth, flat lines instead of randomly like when you crack an egg
Scratch test
when you try to scratch a rock with different objects( like a fingernail or a penny) to see if its hard or soft.
rocks
A naturally formed combination of minerals and other natural materials
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 and lava
