    Native Elements

  • 27

    Chemical properties that are naturally occurring in nature in an uncombined form with a distinct minerals structure. It can be classified as metals, semimetals and nonmetals

  • 28

    This is the largest group of minerals. It contains silicon and oxygen, with some aluminum, magnesium, iron and calcium.

  • 30

    Used in Microchips, Glass and Ceramics, Watch and Clock

  • 42

    Used in Phoschote Fertilizer. Heaith Nutrients, phosphate salt

    phosphate

  • 43

    are naturally occurring, coherent aggregate of minerals or solid materials such as glass or organic matter.

    rocks

  • 44

    They are the hardest and heaviest rock on earth. They are also called the 'new' rocks or magmatic rocks. Sometimes they are referred to as parent rock because all other rock types are formed from them.

    igneous rocks

  • 45

    These rocks form from the cooling and solidification of molten material, either magma or lava.

    igneous rocks

  • 46

    The interlocking texture of grains • The presence of vesicles (holes) in extrusive igneous rocks • May be dark-colored and heavy • May display two grain-sizes, one much larger than the other.

    igneous rocks

  • 47

    Types of Igneous Rocks

    Igneous Intrusive or Plutonic Igneous

  • 48

    develop when magma is trapped deep inside the earth and solidifies without ever reaching the surface. The magma cools and solidifies very slowly over thousands or millions of years in chambers of pre-existing rocks

    igneous intrusive or plutonic igneous

  • 49

    igneous rocks are formed on the earth’s surface when lava exists and cools almost instantly when exposed to a relatively cool temperature in the atmosphere

    igneous extrusive or volcanic igneous

  • 50

    They are made from deposits of preexisting rocks or remains of once-living organisms due to the compression of ocean sediments and other processes. They are commonly found near sources of water, like riverbeds, oceans, ponds, and coasts. Sedimentary rocks are also found in deserts and caves.

    sedimentary rocks

  • 51

    Grains cemented together The presence of fossils Light-colored and light weight May display interlocking grains but is very light weight

    sedimentary rocks

  • 52

    types of sedimentary rocks

    clastic sedimentary rocks

  • 53

    sedimentary rocks derived from mechanical weathering.

    clastic sedimentary rocks

  • 54

    sedimentary rocks from when dissolved minerals precipitate.

    chemical sedimentary rocks

  • 55

    formed by the accumulated sedimentary debris caused by organic processes. These may contain fossils of plants and animals trapped in the sediments as the rock was formed.

    organic sedimentary rocks

  • 56

    form due to the transformation of preexisting rocks in response to environmental changes such as heat, high pressure, and mechanical stress.

    metamorphic rocks

  • 57

    The interlocking texture of large grains Foliation (layering) Banded light and dark colors “ching” sound instead of a “chunk” sound when tapped

    metamorphic rocks

  • 58

    types of metamorphic rocks

    foliated

  • 59

    Have a layered or banded appearance that is produced by exposure to heat and directed pressure. This plating process creates thin layers and directional patterns in the rocks.

    foliated

  • 60

    Do not have a layered or banded appearance. Under high pressure, the minerals compress however they do not align into sheets or platy layers

    nonfoliated
