Earth's system Flashcards
Physical properties
Any property that can be observed using 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 maintains its own shape instead of conforming to the shape of its container.
Liquid
Something that can flow and takes shape of its container like water or juice, but it has a fixed amount of space (volume), similar to how solid stays the same size.
conduct
it allows something like heat or electricity to flow or pass through it easily.
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 u rub it on a hand, rough surface like tile.
Tiles
The colored powder left behind when a mineral is scrapped across a hard surface like a 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 reflect the rest.
Luster
How shiny a rock or mineral is 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 alone smooth,flat lines instead randomly., like when you crack a egg.
Scratch test
Where 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 or 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 it 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 rocks; heat and pressure cause the minerals to form new combinations or new crystals.
