Theory
1. What type of boundary is E? DIVERGENT
What is one feature you would find at E? MID OCEAN RIDGE
2. What type of boundary is G? CONVERGENT
1. Why was Wegener's original idea about continental drift referred to
as intuition and not science?
He didn’t have evidence to support his theory yet
2. What did Wegener find that he believed was evidence to support his
theory?
What is one feature you would find at G? VOLCANOES
3. Youngest type of crust, typically the thinnest but the densest,
constantly being destroyed and remade. Oceanic or Continental?
4. Explain what causes volcanism at D. WHEN ONE PLATE SUBDUCTS
UNDER ANOTHER, MAGMA AND CO2 FROM THE OCEAN FLOOR
MIX. THE GAS HEATS UP AND EXPANDS, CREATING A MAGMA
POCKET. THE MAGMA MELTS THE ROCK LAYERS ABOVE IT
EVENTUALLY FORMING A VOLCANO.
a) Mesosaurus fossils found in Brazil (S. America) and South
Africa
b) Glacial scars in the Karut dessert in S. Africa
3. Why didn't others think that his findings constituted evidence?
He was a meteorologist, not a geologist, and he didn’t have a
mechanism behind his theory (what would make the plates
move?).
Station 3: Topographic Maps
5. What is the geologic feature at D? TRENCH
7. B hill
6. What is the name of the convergent process that occurs when an
oceanic plate meets a continental plate? SUBDUCTION
8. 660 km- the contour interval is 20 meters. The star is located
2 contour lines (40m) below the 700 line. 700-40 = 660 m
7. During a convergent interaction between a continental plate and
an oceanic plate, which plate will be pulled downward (to a greater
degree)? THE OCEANIC PLATE BECAUSE IT IS MORE DENSE
9. 3 km- 1 cm = 1 km, so 3 cm = 3 km

8. What is the name of the plate interaction that describes the
separation of oceanic plates? DIVERGING/RIFTING
9. Identify the type of plate boundary in which plates slide against
one another. TRANSFORM
1. Heated water RISES. Heated water is LESS dense.
Cold water SINKS. Cold water is MORE dense.
QUESTIONS TO ANSWER ON YOUR OWN.
Station 5: Weather USE THE MAP FOR QUESTIONS 1-3
1. Using the map, what type of front does the letter C represent?
A. Cold Front
1. Hurricanes are powerful tropical storms that develop over warm ocean
water. Hurricanes draw their energy from the ocean and weaken as they
move over land. Which of the following BEST explains how energy is transferred
from the ocean to a hurricane?
B. Warm Front
a. Evaporating water adds heat to the atmosphere.
C. Stationary Front
D. Occluded Front
b. Rising tides change the level of the ocean surface.
c. Currents carry warm water along the ocean surface.
2. Using the map, what type of front does the letter B represent?
A. Cold Front
B. Warm Front
C. Stationary Front
D. Occluded Front
3. Which direction is the front of letter B moving (where is it
headed?)
NORTH.
2. In the Northern Hemisphere the reason that cold fronts are often preceded
by rain and cloudy weather which quickly clears to reveal bright, clear skies
and sunshine, accompanied by colder temperatures is primarily due to the
fact that –
A. Low pressure systems that push cold air south often accumulate unstable
moisture in front of them.
B. High pressure systems that push cold air south often accumulate unstable
moisture in front of them
C Water cannot evaporate in very cold air, so rain storms cannot develop
behind cold fronts.
3. Earth’s land areas, oceans, and atmosphere maintain fairly constant
average temperatures. What is the best explanation for these constant
average temperatures?
A Earth’s Northern Hemisphere and Southern Hemisphere have opposite
seasons.
4. Which letter represents a stationary front? C
5. Which letter represents the cold front? A
6. Which letter represents the warm front? B
B
Earth is tilted and rotates daily on its axis.
C
The continuous motion of air and water distributes the sun’s energy.
