100
What are the four layers of the Earth from outside to inside?
What is crust, mantle, outer core, inner core
100
Who came up with the theory of Continental Drift, and where was he from?
What is Alfred Wegener was from Germany.
100
What is a fault?
What is A crack or break in the Earth's crust where movement can occur. ****
100
What are the tectonic plates doing at the mid- Atlantic ridge?
What is Spreading apart- Divergent boundary *******
100
What is a topographic map?
What is A map that show earth's surface features.
200
What are the differences between the inner and outer core? Give at least two answers.
What is Pressure increases and temperature increases as you go deeper into the Earth. The outer core is liquid, and the inner core is solid. ****
200
What is the name of the giant landmass that existed 250 million years ago when all the Continents were together?
What is Pangaea ****
200
Where do most earthquakes occur and why?
What is The edges of the plate boundaries because the plates are moving releasing energy in the form of seismic waves.
200
How are non volcanic mountains formed and give an example of where this is occurring
What is two continental plates collide. This happened to form Mt. Everest.
200
Using a contour map, how would you know where the steepest areas were?
What is If the lines are close together, the area is steep.
300
What are the two types of crust, and how are they different (besides the obvious)
What is Oceanic Crust and Continental Crust. Ocean crust is thinner and denser. Continental Crust is thinker and less dense.
300
Explain Alfred's theory of Continental Drift and why no one believed him.
What is At one time the Continents were together in one giant landmass called Pangaea and over time drifted to their present locations. No one believed him because he couldn't say HOW the Continents could move.
300
What's a hotspot and name two places in the United States where this is occurring.
What is places in the middle of plates where hot plumes of magma rise, forming volcanoes. Hawaii and Yellowstone.
300
What is subduction and why does it happen?
What is When an ocean plate slides under a continental plate because the ocean plate is more dense. ******
300
Name the 7 continents and the 4 oceans.
What is North America, South America, Asia, Africa, Australia, and Antarctica. Pacific, Atlantic, Arctic, Indian
400
Which specific layer of the Earth do the Tectonic plates sit on top of, and how does this layer behave?
What is The plates sit on top of the Asthenosphere. This layer acts like toothpaste, putty, or frosting and can move very slowly.
400
What was the name of the Fossil that was found to help support the idea of Continental Drift?
What is Mesosaurus or Glossopteris
400
Earthquakes release energy in what form? What term describes the strength of an earthquake? What term describe the damage an earthquake causes?
What is seismic waves. Strength is magnitude. Damage is intensity.
400
What process in the mantle causes the plates to move. Explain this process in detail.
What is Convection Currents- The core heats magma closest to it which makes it less dense. This material rises. Colder parts of the mantle have a higher density and will sink.
400
Name two trenches we learned about this 9 weeks. How were they formed?
What is Java Trench, and Aleutian Trench- Formed from subduction. *****
500
How do scientists know what's inside the Earth? Explain three different ways.
What is Scientists observe the material from volcanoes. Scientists look at meteorites from space. Scientists observe the behavior of seismic waves. Scientists subject crustal rocks to extreme heat and pressure.
500
What were four pieces of evidence that Alfred Wegener used to support his theory.
What is Matching coastlines, Same age and type of rock, fossil evidence, climate change evidence, and continuous mountain chains.
500
using the map, show three areas of Volcanism and also explain why these areas have volcanoes.
What is Subduction zones (ring of fire), Ocean ridges (divergent boundaries) and Hot spots (middle of plates)
500
What are the three plate boundaries and what is formed at each?
What is Convergent- Continent + Continent= Mountains Convergent- Ocean + Continent= Subduction= Trenches and Volcanoes Convergent- ocean+ ocean= island arcs Divergent- Plates spread making rifts and ridges Transform- Plates slide past each other causing earthquakes
500
Name all 9 pen pal locations and their earth structure.
What is Argentina- Mt. Aconguaga , Mt. Popo Mexico, Mt. Fugi Japan, Hawaiian Islands, Iceland, Baja California, Peninsula, Mt. Kilimanjaro Tanzania, Mt Everest, Nepal, Java trench in Indonesia
