Earths system Flashcards
Any property that can be observed using the five sense or can be measured without changing the matter.
Physical properties
Weight- how heavy an object is [ mass is how much ‘stuff’ [ matter] something is made of]
weight/mass
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 fixed amount of shape [ volume], similar to how a solid stays the same size.
liquid
it allows something like heat or electricity to flow or pass through it easily.
conduct
energy that moves from something hot to cold, a form of energy.
heat
A substance found in nature, minerals make up rocks.
minerals
how easily or different it is to scratch a minerals surface.
hardness
the color of its powder when you rub it on a hard , rough surface like a tile.
streak
the colored powder left behind when a mineral is scraped across a hard surface like a ceramic tile, which helps identify mineral by its ‘streak’ color.
tiles
its what light reflects back to our eyes. minerals are colored because they absorb some colors of light and reflects the rest.
color
how shiny a rock or a mineral 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.]
luster
How some minerals break along smooth, flat lines instead of randomly. like when you crack an egg.
cleavage
where you try to scratch a rock with different objects [ like a fingernail or a penny] to see if its hard or not.
scratch test
Surface, erosion, weathering, rapid, drastic, slow changes, landslide, volcano, earthquake, magnetic
Supporting vocabulary
A naturally formed combination of minerals and other natural minerals
rocks
A solid , naturally formed substance that always has the same properties.
Minerals
The dirt and stuff that settles to the bottom of liquids or is carried in then deposited by water, wind or ice
sediment
Rock formed from compacted sediment
sedimentary
Rock formed from magma or lava
igneous
Rock formed from existing rock; heat and pressure caused the minerals to form new combinations or new crystals
metamorphic
Magma- molten rock within Earth.
Attributes or characteristics
pressure- is like a push or squeeze that and that pressure helps change the rocks in earth
Rock cycle- the continuous process of change which is new rocks are formed from old rock Mentors.
