The Earth
Weathering
100
This is used to measure the magnitude of an earthquake
What is a seismograph
100
This is what formed the Hawaiian Islands.
What is the pacific plate moving over a hot spot.
100
What theory did Alfred Wegner propose?
What is continental drift
100
These are the layers of the earth in the correct order starting for the innermost layer.
What is inner core, the outer core, the mantle and the crust.
100
These are two types of weathering
What is chemical and mechanical weathering
200
Seismic waves come in, in this order...
What is primary waves, secondary waves (s-waves) and then surface waves (L-waves)
200
DAILY DOUBLE What volcano has most southern BCers worried?
What is Mt. Baker
200
This is what Alfred Wegner used as evidence of continental drift.
what is fossil evidence
200
If you cut an apple in half, this is one strength and one weakness of this being a model of the earth.
What is strengths- the solid inner core (seed), the large mantle (thickest layer), crust is solid weaknesses- the nonexistent outer core, the mantle is solid and flexible (taffy) instead of the same throughout
200
These are two examples of mechanical weathering.
What is frost wedging, burrowing animals, growing plants
300
This is the scale used to DESCRIBE the strength of an earthquake.
What is the Richter Scale.
300
As scientists gathered evidence for continental drift, a new theory and name was formed.
What is the theory of plate tectonics
300
The earth crust floats on this melted rock
What is magma
300
These are two examples of chemical weathering.
What is acid rain and limestone caves
400
These run parallel to rock layers and these run across rock layers (2 answers in the right order)
What are sills and dikes
400
Scientists gathered this evidence showing the continents and sea floor were moving (name 3 ways they proved it)
What is sea floor spreading (process in which sea floor increases in size because formation of new crust), sonar technology (sound waves sent out to measure depth), seismic waves, core samples, and magnetic reversals.
400
This was called the 'super continent' before continents moved apart 250 million years later.
What is pangaea
400
This is what a magnetometer does.
What is a sensing device that detects magnetic fields
500
This is the reason plates are moving on the crust.
What is convection currents in the mantle
500
This is what is done to minimize the problems of living near a volcano.
What is... Early warning systems in place Flood management Evacuation plan urban planning Emergency supply preparedness Vog proofing plants
500
These are the three different types of plate boundaries and examples of each...
What is 1. convergent boundary - Juan Fuca Plate subducting under North American plate 2. divergent boundary - mid atlantic ridge 3. transform boundary- san andreas fault
500
These are three features formed by glaciers.
What is moraine, cirque and a horn
500
DAILY DOUBLE On the board I drew a diagram of a volcano, labelling 5 features.
What is ....see the board and check with Miss. Teillet!
