resources that supply our everyday

needs!

It’s the solid crust

and solid mantle

near Earth’s

surface where

rocks and

minerals are

found!

In your

layers and their

depths

rocks and minerals?

Here are the clues in the rocks and minerals we will use to identify them and piece together the history of Earth

COMPOSITION (CONTENTS)

TEXTURE (FEATURES)

STRUCTURE (PATTERNS)

What the rock or

mineral is made of

The appearance of

a rock or mineral

The patterns you see in a

rock or mineral caused by

how it formed

… naturally occurring or synthetic (man-made)?

… organic (once living) or inorganic (non-living)?

… crystalline solid, liquid or gas?

… one (unique) or multiple (variable) chemical composition(s)?

MINERALS are the building blocks of rocks!

MINERAL IGNEOUS ROCK

• Formed from melting of other rocksinto molten magma

• Magma cooled and solidifiedTEXTURE

• Interlocking crystals in random pattern

• Fine to very coarse crystals• Glassy (no crystals)• May have gas pockets (vesicular)

ROCK?

MINERAL IGNEOUS ROCK

SEDIMENTARY ROCK• Other rocks broken down into

sediments of same or mixture of sizes• Sediments cemented back together

TEXTURE • Grains are not interlocking. They are

cemented back together (two materials)• Fossils• Flat layers because they formed mostly

on ocean floor)• Muddy looking if small silt/clay

particle sizes

MINERAL IGNEOUS ROCK

SEDIMENTARY ROCK METAMORPHIC ROCK• Formed from extreme heat and pressure

of other rocks, but not enough heat to melt original material

TEXTURE • Interlocking crystals• Pressure can deform layers and fossils

(appear stretched out or squished)• Layers discontinuous and can be wavy• Platey minerals (shiny flat plates)

Unique or variable composition?

◦Made of many things in different proportions likeinorganic minerals

organic materials (shells, dead plants)

other rocks in various proportions.

Crystal Cave was undisturbed for 600,000 years and then humans disturbed the balance

Water was drained because of nearby mining of gypsum (drywall main ingredient)

The cave was discovered when it was drained

Will the crystals survive?
