Earth's system Flashcards
Any property that can be observed using the five senses 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 its 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
it allows something like heat or electricity to flow or pass through it easily.
conduct
energy that moves from something hot to something cold, a form of energy.
heat
A substance found in nature, minerals make up rocks.
minerals
how easily or difficult it is to scratch a mineral’s surface.
hardness
the color of its powder when you rub it on a hard, rough like a tile.
streak
the color left behind when a mineral is scraped across a hard surface like a ceramic tile, which helps identify the mineral by its “streak” color.
tiles
its when lights reflect back to our eyes. Minerals are colored because they absorb some colors of light and reflect the rest.
color
how shiny a rock or a mineral looks when lights shines on it, like a mirror,or glassy,or even dull. (Luster is a physical property used by mineralogists to help identify minerals).
luster
How some minerals break a long smooth, flat line instead of randomly, like when you crack a egg.
cleavage
where you try to scratch a rock with different object (like a fingernail or a penny) to see if its hard or soft.
Scratch test
A naturally formed combination of minerals and other natural materials.
rocks
A solid, naturally formed substance that always has the same composition and the same properties.
minerals
the “dirt and stuff” that settles to the bottom of liquids, or is carried and 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 cause the minerals to form new combinations or new crystals.
metamorphic
