Bell Work 4/15/14

• TCAP PRACTICE QUESTIONS
• Complete question 26-30
• Please do NOT write in TCAP booklet!
• Bubble in the correct answer on the bubble sheet
  provided.
• Scan your bubble sheet and record your score.
• We will discuss the questions after everyone has
  scanned.
• You have 5 minutes to answer the questions.
• Your time starts as soon as the bell rings.

Chp. 13-18 Objectives Covered

• SPI 0707.7.1 Use a table of physical properties
  to classify minerals.
• SPI 0707.7.2 Label a diagram that depicts the
  three different rock types.
• SPI 0707.7.3 Identify the major processes that
  drive the rock cycle.
• SPI 0707.7.4 Differentiate among the
  characteristics of the earths three layers.
• SPI 0707.7.5 Recognize that lithospheric plates
  on the scale of continents and oceans continually
  move at rates of centimeters per year.
• SPI 0707.7.6 Describe the relationship between
  plate movements and earthquakes, mountain
  building, volcanoes, and sea floor spreading.
• SPI 0707.7.7 Analyze and evaluate the impact of
  mans use of earths land, water, and atmospheric
  resources.

Mineral Identification

• Color
• Not the best way to identify a mineral because
  the same mineral can come in a variety of colors
  or different minerals can also be the same color
• Luster
• the way a surface reflects light (metallic,
  pearly, waxy, etc.)
• Streak
• the color of the powder that a mineral leaves
  behind
• Cleavage/Fracture
• The different ways a mineral can break
  (smooth/flat or rough/jagged)
• Hardness
• a minerals resistance to being scratched (Mohs
  Hardness Scale 1 (soft Talc)-10 (hardest
  Diamond)
• Density
• the ratio of the mass of a substance to the
  volume of the substance the measure of how much
  matter (mass) is in a given amount of space
  (volume)
• Special Properties
• Special characteristics of a mineral
  (fluorescence, odor, magnetism)

3 Types of Rocks
Igneous Rocks Sedimentary Rocks Metamorphic Rocks
How Forms when magma (hot, liquid rock) cools and hardens Where on the Earths surface (extrusive) or beneath the Earths surface (intrusive) Example Obsidian How when rocks are broken down into sediments and those pieces of sediment form layers that are compacted and cemented together Where on the Earths surface from weathering, erosion, deposition Example Sandstone How rocks in which the structure, texture, or composition of the rock have changed because of heat and pressure Where deep within the Earth (below the surface) Example Marble

Processes of the Rock Cycle

• Melting
• Under extreme heat, rocks can melt into magma
• Cooling and Hardening
• Magma will cool and harden into igneous rocks
• Weathering, Erosion, Deposition
• Weathering breaks down the rocks
• Erosion carries the sediments away
• Deposition drops the sediments (like its hot!)
• Compaction and Cementation
• Sediments create layers and over time these
  layers are compacted and cemented together
• Heat and Pressure
• Under extreme heat and pressure rocks can change
  form (metamorphism)

Layers of the Earth

• Crust
• outermost layer of Earth thinnest layer (1 of
  Earth's mass) two types of crust continental
  and oceanic crust
• Mantle
• thickest layer of Earth between the crust and
  core (67 of Earth's mass) solid rock that flows
  (silly putty rock- convection currents)
• Outer Core
• liquid iron and nickel
• Inner Core
• Solid iron and nickel

Plate Tectonics

• Tectonic Plates
• parts of the lithosphere that move around on top
  of the asthenosphere (middle mantle)
• Types of boundaries
• Transform- plates slide past each other causing
  earthquakes
• Divergent- plates move apart causing sea-floor
  spreading and volcanoes
• Convergent- plates collide causing mountains and
  volcanoes
• Pangaea
• Alfred Wegener believed that the continents were
  one single landmass called Pangaea, they
  separated, and drifted apart to how they are
  today (continental drift)

Earths Resources

• Renewable Resources

• Nonrenewable Resources

• Resources that can be renewed or used again in
  our life time (fresh water, solar power, trees,
  etc.)

• Resources that cannot be renewed or used again in
  our life time once it is used, it is gone and
  will take hundreds, upon thousands of years to
  renew (fossil fuels, like coal, oil, and natural
  gas)
