Practice Questions: Tectonic Plates

Read pages 86-101, 103-104, 108, 111-112

  1. Explain why the plastic nature of the asthenosphere and convection currents are important to the theory of plate tectonics.

Because under pressure they can flow slowly. Connection current heats up then expands, which then begins the rise to the surface, the cooler part sinks setting up a convection current.

  1. Which type of plate boundary is:
    • Found at mid-ocean ridges?
  2. Diverging
    • Most often associated with forming mountain belts on continents?
  3. Collision
    • Associated with the San Andreas fault?
  4. Transform Fault
  1. Is it better to live near a regularly active fault line or an inactive fault line? Explain.

Yes. Because the more action the less tension there is on the line. The less action would result in massive pressure being build up resulting in a massive shock.

  1. Explain why volcanic activity along transform faults is relatively rare.

 

  1. Use a plate boundary map to explain why Japan and Indonesia should face more earthquakes than anywhere else in the world. (provide the map you used in your post)
  2. Use a plate boundary map and explain how plate tectonics would affect where you live.
  3. Use a plate boundary map and explain the relationship between the position of volcanoes, fault lines and plate movement.
  4. Using a plate boundary map and the population density map below, which countries are at risk of having many people affected by earthquakes and volcanic activity?popdensity

  1. How do the formation of rocks affect your life? Organize your response by rock type.

We use oil, minerals for our devices, watches have quarts, roads, gravel roads, metals for our tables, for example, copper pots and for electricity.

  1. In what ways is the rock cycle affected by the energy of the earth, the atmosphere, and the hydrosphere? Explain which rock types would be affected by each.

Rock being forced back into the earth melts into magma because of the heat. The atmosphere and hydrosphere wash sediments which layers into rocks, erosion breaks down rocks.

  1. Explain why sedimentary rocks usually do not contain metallic minerals.

metallic materials are denser. heavier materials sink and settle at the bottom of rivers. Lighter materials travel further in a river.

  1. Look ahead to the map on page 87, explain where in Canada you would expect to find metamorphic rocks forming.

We are looking for subduction which creates pressure and heat to create a more harder version of its original form.

  1. If you were attempting to discover oil and gas deposits in Canada, what conditions would you be looking for?

Looking for sediment rock, signs that there used to be a river in the area, evidence of a former ocean or lake.

  1. Explain how it is possible to distinguish between sedimentary and metamorphic rocks that appear layered.

Metamorphic rocks have a vein of minerals rather than a sediment which has layers of sediments. Metamorphic rocks are harder than sedimentary.

  1. Use the rock type map of Canada to identify the major rock types for each province/territory and the possible resources that may add to their economyrocktypemap
  2. Explain how rocks can affect politics and economics around the world. Give specific examples.

Oil dispute between BC and Alberta which falls under the government. Gold rush in BC created a larger population.

Winter Poem

A Winter’s Day

It is when time slows down to longer appreciate the silent night

What is winter?

It is the covering of fall’s canvas with white paint

It is the powdered sugar adorns the plain donut with a jelly surprise inside

It is the dust in the closet that is closed for a few months until the cleaning breeze of Spring opens the door

It is the frozen touch of a loved one lost
