Supporting evidence to Wegener's theories was the discovery of similar ______________ of plants and animals on different continents.
ages
fossils

Scientist Alfred Wegener theorized that long ago, there was only 1 large super continent but over time, it broke into parts which moved away from each other. His theory was known as...
Continental Drift
Drift Baby Drift
Super Drift
Continental Break Up
In the early 20th century (early 1900's), what name did Wegener give the super continent?
Super Continent
Biggy C
Pangea
PanaSeeYa
Plate boundaries that are moving away from each other are know as...
Divergent Plate Boundaries
Transform Plate Boundaries
Convergent Plate Boundaries
Compression Plate Boundaries
Plate boundaries where one plate subducts under crust that is less dense are know as...

When a fossil of an animal is found on almost all continents, then it supports
the idea of a traveling animal
the idea of a connected original continent
the idea of a flying animal
Describe the most likely relationship between these mountains and nearby tectonic plates.
The mountains are probably formed by earthquakes
The mountains are probably formed by the movement of glaciers
The mountains are probably located near the edge of 2 tectonic plates.
The mountains are probably formed by running water.
Is there a pattern to the locations of earthquakes and volcanoes around the globe?
No, earthquakes and volcanoes are random.
Yes, earthquakes and volcanoes usually occur near the boundaries of tectonic plates.
yes, earthquakes and volcanoes usually occur in the middle of tectonic plates.
No, earthquakes and volcanoes usually occur under water.
A map is provided that presents information on a certain region of the Earth. Based on the information on the map, at which location are mountains most likely to form?
A
B
C
D
The Ring of Fire is an area where a large number of earthquakes and volcanic eruptions occur. What claim can be made about the Ring of Fire from this information?
It is the only place on Earth where earthquakes can happen.
The edges of the tectonic plates are moving in this area.
It represents the areas where tectonic plates are the thickest.
It has been getting larger since Earth first formed.
Rocky or rigid outer part of Earth consisting of the brittle crust and the top part of the upper mantle
Lithosphere
Oceanic Crust
Continental Crust
Asthenosphere
Hot fluid or semi-fluid material below or within the earth's crust from which lava and other igneous rock is formed on cooling.
Convection Current
Lithosphere
Core
Magma
Which statement best describes why fossils of the same land-dwelling species have been discovered in both South America and Africa?
The organism migrated to two continents
The organisms were separated by the formation of new mountain ranges
The organisms became extinct due to climate change on these continents
These organisms once lived on one large landmass that later split into two continents
Observe this diagram of a plate boundary. One statement BEST describes what is happening. It is that
the oceanic crust is melting.
the denser oceanic crust is subducting under the less dense oceanic crust
volcanic islands are forming.
the tectonic plates are moving away from each other.
Alfred Wegener's Continental Drift Theory states that...
there was once an original land mass that was 1/2 the size of all the current continents.
there was once an original land mass that was 3 times the size of today's continents and there was only a small amount of water.
there was once an original land mass that was composed of all the continents.
for every action, there is an opposite and equal reaction.
What was one (1) piece of evidence for the Continental Drift Theory?
There were nearly identical rock layers on continents that would have fit together.
Alfred Wegener asked people on other continents what they thought about his theory.
All the plants and animals in all parts of the world were exactly the same.
The fossils on other continents were very different.
Princeton University geology professor, Harry Hess, helped prove Alfred Wegener's Continental Drift theory with the discovery of what scientific process?
Seashore Shelling
Seafloor Spreading
Seafloor Contractions
Sea Life Extinction
By bouncing sound waves off of the ocean floor, scientists discovered...
that the ocean floor is an endless abyss.
in the middle of the Atlantic, Pacific, and other oceans around the world there are mountains and rift valleys.
in the middle of the Atlantic, Pacific, and other oceans around the world there are a variety of animals that cause seafloor spreading.
in the middle of the Atlantic, Pacific, and other oceans around the world there are alien spaceships.
For this question, you MUST PICK 3 ANSWERS:
What evidence is there to support Seafloor Spreading?
The temperature of drilled samples increases the closer to the mid-ocean ridges indicating that super hot magma exits under them.
The youngest rocks are found along the mid-ocean ridge and they become increasingly older the farther away from the ridge.
Alien spacecraft has been found on the ocean floors and data has been retrieved from them to support seafloor spreading.
Basalt on the ocean floor contains iron rich rock that is magnetized and aligns itself with Earth's magnetic poles, much like a compass.
Using and comparing pictures from the ocean floor from hundreds of years ago, scientists are able to measure the distance the tectonic plates have moved.
