100
13.7 billion years
What is the age of the universe?
100
the layers of the earth
What is inner core, outer core, mantle and crust
100
The main scientist credited for describing plate tectonics and continental drift?
Who is Alfred Wegener
100
the cause of earthquakes are these
What is the tension built up by shifting plates causes sudden release and this creates a waves of vibration in the crust, expanding out radially. Can occur at transform and convergent boundaries.
100
the three types of volcanoes are these
What is cinder cone, shield and composite
200
everything in the universe is packed into one ball
What is the singularity ball
200
the magnetic field is generated by rotation of this layer. and is made primarily of what material?
What is the outer core. Thought to be made of iron and nickel
200
the main evidence for continental drift includes these clues.
What is fossil records, the way the continents fit together, glacial records on different continents.
200
the seismograph
What is the instrument to measure earthquakes.
200
The reason volcanoes are found clustered around earthquakes is this.
What is volcanoes occur at plate boundaries.
300
Steven Hawking
What is a scientist important in describing the formation of the universe
300
The final layer of earth is not the crust but this.
What is the atmosphere
300
The big difficulty for scientists to accept the theory of plate tectonics was solved by this.
What is convection currents in the mantle
300
the three phases of a tsunami are described as this.
What is initiation, wave, amplification
300
The ring of fire.
What is the pacific plate boundary has many volcanoes and earthquakes.
400
asteroids colliding about 4.5 billion years ago
What is formation of the earth
400
The 5 layers of the atmosphere are called this.
What is Troposphere, stratosphere, mesosphere, thermosphere and exosphere.
400
the three main types of plate boundaries are these.
What is convergent, divergent, transform
400
If you are in an earthquake you should do this.
What is duck and cover
400
What are 5 things you can do to prepare for an earthquake?
What is 1)have a plan 2) keep heavy things low to the ground, 3) have non-perishable food and water 4) have a flashlight 5) have a transistor radio 6) have batteries and money 7) have a first aid kit (with medicines)
500
liquid energy
What is the form of the baby universe
500
the two main gasses in the atmosphere are these and they are found in approximately these amounts.
What is Nitrogen and Oxygen (80% and 20%)
500
the explanation for how plate recycle
At divergent boundaries (using under the sea, called sea floor spreading), magma oozes up at a rate of about 2 cm./year. As it hits the surface, it cools creating new plates. At convergent boundaries, where the less dense plates collide with more dense plates, they subduct, dropping back into the mantle.
500
Ways to protect houses and buildings from earthquakes include this.
What is sheerwalling (cross bracing) and bolting the foundation.
500
The reason that tidal wave is a bad translation for Tsunami
What is tsunamis are underground earthquakes and ahve nothing to do with tides.
