1. Of the two main sources of Energy that drive the Rock Cycle:
1) Earth’s Internal Heat
2) Solar Energy
Match these primary sources of energy to the rock types listed below, meaning that this energy source is responsible for the formation of this rock type.
Sedimentary Rocks are primarily formed by __________
Igneous Rocks are primarily formed by ____________
1. Match the Plate Boundary Type with the given locations/features on Earth
|Continental rift||A.East African RiftB.Himalaya Mountains along the Indian PlateC.San Andreas fault in CAD.Mid-Atlantic Ridge|
1. Wegener’s Continental drift hypothesis paved the way towards our understanding of how the Earth’s surface is moving and changing! Which of the follow is NOT evidence that Wegener and his supporters gathered to substantiate (“prove”) the continental drift hypothesis?
|Fossils match across the seas|
|Mountain ranges and rock types match on different continents|
|Ancient climates match, as seen in glacial desposts across several continents|
|The continents appear to fit together like a jigsaw puzzle|
|The mechanism for the movement of the continents was proven, explaining exactly how the plates drifted|
1. Identify the rock in the image ( CLICK on “Rock_1.jpg to download the image ). Is it sedimentary, igneous or metamorphic? Can you give a more specific name for this rock
1. Plate movements can affect which of the following earth systems/processes?
|D.||Migrating Continents and Oceans|
|E.||All of the above|
1. Identify the rock in the image ( CLICK on “Rock_2.jpg to download the image ). Is it sedimentary, igneous or metamorphic? Can you give a more specific name for this rock?
1. Think About It: If other planets in our Solar System are not displaying signs of Plate Tectonic motions, what can be inferred about the state of the interior of these planets? (What does this tell us about the state of the interior of other planets in our Solar System)
1. When a rock is heated, when pressure increases, or when hot water alters its chemistry, both its minerals and its textures change in a process called _____________.
1. When a sedimentary rock is created it forever remains a sedimentary rock, never changing.
|A.||Zone in the upper mantle that deforms by plastic flowage|
|B.||Cool, ridge layer of crust and upper mantle that forms the tectonic plates|
|C.||Deforms mainly by brittle fracturing and faulting|
|D.||Hard surface which floats on top of molten material|
1. All of the following are current evidence supporting the theory of plate tectonics except for _________.
|changes in the Moon’s orbit due to shifting plates|
|ocean floor drilling|
1. Rocks that contain crystals that are roughly equal in size and can be identified with the unaided eye are said to exhibit a _______ texture.
1. Subduction zones are associated with a _________ plate boundary.
|B.||All plate boundaries|
1. Use the Plate Tectonic Boundary Map on pages 202-203 in your textbook to answer the following questions:
Describe the tectonic motion taking place between then African Plate and the Eurasian plate. What major geological feature exists there and why?
|Divergent Boundary. Alps Mountain range, formed from plates pusing together and compressing, building up the mountain range.|
|Convergent Boundary. Alps Mountain range, formed from plates pusing together and compressing, building up the mountain range.|
|Divergent Boundary. Alps Mountain range, formed from plates pulling apart and decompressing, building up the mountain range.|
|Transform Boundary. Alps Mountain range, formed from plates sliding past one another therfore building up the mountain range.|
1. There are two main types of igneous rocks. Blank 1 igneous rocks are formed from magma that cooled very quickly and are fine-grained. These can also be called Blank 2 igneous rocks. The second type of igneous rock is Blank 3 igneous rocks which are coarse-grained because the magma from which they formed cooled slowly. These can also be called Blank 4 igneous rocks.
1. Shells and other hard parts of animals such as calms, oysters and corals are comprised of carbonate minerals that eventually become limestone. This is an example of how changes in the _____________perturb the _______________.
1. The Lithosphere is being consumed at Term 1
, and being produced at Term 2
1. , which happens at the same rate, allowing for the Earth to reamain the same relative size.
1. Alfred Wegener’s concept of a single supercontinent that broke apart to form the modern continents is called the theory of ______________…..which was later re-named once scientific data confirmed what was causing the plates to move.
1. Most common igneous rocks are named in pairs, each member having the same Blank 1 but different Blank 2. An Example is Granite and Rhyolite.
1. Sedimentary Rocks are broadly divided into four categories. For the definitions given, match the correct type of sedimentary rock.
|Sedimentary rock derived from plant and animal remains. And example is Coal, which is formed from partially decayed plants called peat.|
|Halite is a good example of this type of sedimentary rock. Halite is an evaporate because the salt precipitates from the seawater|
|Derived from the weathering of pre-existing rocks. Sandstone is an example of this type of sedimentary rock|
|Derived from biological clasts. Limestone is a good example.||A.Bioclastic sedimentary rocksB.Detrial or Clastic sedimentary rocksC.Chemical sedimentary rocksD.Organic sedimentary rocks|
1. Probably the single most characteristic feature of sedimentary rocks is layering.
1. Which of the following energy sources is thought to drive the lateral motions of Earth’s lithospheric plates?
|export of heat from deep in the mantle to the top of the asthenosphere|
|swirling movements of the molten iron particles in the outer core|
|gravitational attractive forces of the Sun and Moon|
|electrical and magnetic fields localized in the inner core|
