Types of Energy
TRUE OR FALSE: Coal and natural gas are types of renewable energy.
False
The temperature _________ as you go deeper into the Earth.
increases
What was the scientist's name who came up with the 3 observations that there was one big supercontinent?
Alfred Wegener
Besides convergence and divergence zones, where are volcanoes formed?
Hot spots
TRUE OR FALSE: Tsunami phenomena begin and end on land only.
False
What about Quebec makes it a major user of hydroelectric energy?
There's a lot of water in Quebec
Name the 4 layers below the crust, in order.
Upper mantle, lower mantle, upper core, inner core
What is the name of the supercontinent? (Spell it)
Pangea
What is lava?
It is what magma is called when it is on the surface of the Earth.
Which zone do MINOR earthquakes happen in?
Divergence zone
Give an advantage (pro) of using nuclear energy.
-Very efficient (1 power plant for a whole city)
-No greenhouse gases
In what type of zone does a subduction process occur?
Convergence zone
Panthalassa
What is the area with a chain of volcanoes called?
Ring of Fire
What instrument measures the strength of an earthquake?
Seismometer / Seismograph
Give a disdvantage (con) for geothermal energy.
-You need to dig into the ground, which is difficult and expensive.
-Digging can cause instability.
What can form in a divergence zone? Give one example.
Faults
Explain Alfred Wegener's observation of FOSSILS.
Fossils of certain animal and plant species were found on different continents.
Explain how a volcano occurs at a divergence zone.
The plates are pulled apart. The crust is broken and magma is forced upwards and flows as lava.
10 times stronger
Wind turbines and solar energy provide renewable energy. Why aren't there more of them around?
(Answers will vary)
Describe in detail how convection currents work to move tectonic plates.
Hot magma near the inner core becomes hotter and less dense, so moves upwards. As more magma rises up, it pushes upper magma to the side, which sinks down when it cools.
Explain BOTH observations:
- Geographic maps
-Composition of rocks
-Continents look like the fit together as puzzle pieces
-The type of rocks found on mountains on different continents seemed to be made of the same things and the same age.
Be as detailed as possible: how were the Hawaiian Islands formed?
The asthenosphere is hotter in certain places than in others. In these areas, magma is forced to the surface and an underwater volcano is produced. The lava accumulates and cools thereby eventually forming islands.
How much stronger is an earthquake of 1 compared to an earthquake of 6?
100 000 times stronger
