Assume that the diagram below shows a cross section of part of the lithosphere.
Which diagram correctly shows what will happen to the lithosphere when pushed by tectonic forces?
In 1912, Alfred Wegener proposed the theory of continental drift, stating that all the continents were once joined together and slowly moved apart. However, his theory was not widely accepted in his time. In 1962, the discovery of sea floor spreading (sea floor being forced apart by the formation of new crust) eventually led to a more modern and widely accepted theory of plate tectonics.
Why did the theory of plate tectonics improve upon Wegener’s theory of continental drift?
The theory of plate tectonics was a less complete theory because it provided a reason and mechanism for why the plates and continents moved.
The theory of plate tectonics was a more complete theory because it failed to provide reasons and mechanisms for why the plates and continents moved.

Ancient fossils have been placed on the map indicating where they were found.
The strongest evidence exists for which two continents to have been connected when Pangaea was present?
South America and Africa
North America and Africa
Africa and Australia
South America and Australia
The map below shows the present day locations of South America and Africa. Remains of Mesosaurus, an extinct fresh water reptile have been found in similarly aged rock layers formed from lake sediments.
Which statement represents the most logical conclusion from this evidence?
Mesosaurus migrated across frozen oceans from Africa to South America during an ice age.
The continents of South America and Africa were once joined when the Mesosaurus lived.
The continents of South America and Africa once had underground waterways where the Mesosaurus travelled from continent to continent.
The continents of South America and Africa had very different climates from each other which caused the Mesosaurus to migrate from season to season.
The diagram below shows the continents present day continents once joined together as one super continent.
What is the name of this one large landmass?
Eurasia
Gondwanaland
Laurasia
Pangaea
The Mesosaurus was a fresh water reptile that existed on Earth about 250 million years ago. Fossils of the reptile can be found today in some rock layers in both Africa and South America as shown on the map below in locations X and Y.
Which reason bestexplains why fossils of this animal are found on both continents today?
The ocean between the two continents was once frozen, and the Mesosaurus traveled across the ice.
The continents were once joined together as a single land mass.
The Mesosaurus swam across the ocean due to its migration.
During a sea level rise and floods fossil remains of the Mesosaurus were carried across the oceans between the two continents.

There are two kinds of glaciers:
Alpine and Ice sheet
Northern and southern
Erratic and Moraine
Bulldozers and Lake diggers
The great lakes were created by:
Weathering of river beds that expanded the rivers so much, they enlarged to lakes.
Diverging plates that allowed ground water to seep into the cracks left behind.
Giants throwing temper tantrums on the land - stomping holes and filling them with their tears.
Glaciers that carved deep holes in the landscape and left ice within to melt after they retreated.
