Who is the scientist that developed the Continental Drift Theory?
Anton Wagner
Alfred Wegener
Archie Bunker
Alfonso Ribeiro
What is the Theory of Continental Drift?
There is a gravitational force that is acting on Earth's land masses, pulling them apart at a rate of 1-2 cm per year.
The continents are located exactly where they will remain for the next 250 million years.
The Earth was once a molten mass that has since cooled and contracted, separating the continents by vast oceans.
The continents were once together in one large land mass but they have since drifted apart.
What do you call the supercontinent landmass formed million years ago?
Pangea
Panera
Polymorphism
Palendrome
What do you call the evidence of Wegener's Theory that tells about the remains of an organism that lived long time ago?
Bones
Folicles
Fossils
Ashes
What type of evidence supported Wegener's Theory of Continental Drift?
Evidence of Climate C
hange
Fossils
Mountain Ranges and landforms
All of the Above
One of the pieces of fossil evidence Wegener found was from a fern-like plant called what?
Gabagool
Glossopteris
Gladiolus
Gargantuan
What are the two continents that fit together based on Wegener's Theory, and that sparked his curiosity to find further evidence to support it?
India and Asia
Russia and North America
Africa and South America
Africa and Asia
What is a theory?
an indisputable observation of a natural or supernatural phenomenon
a widely held but false belief or idea rooted in careful observation but faulty scientific method, but which attempts to bring together many facts and hypotheses thought to be true
something that has no possibility of any other result; something that you know will happen in a particular way
a carefully thought-out explanation for observations of the natural world that has been constructed using the scientific method, and which brings together many facts and hypotheses.
What are the three types of Evidence that supports Alfred Wegener's Theory?
Fossils, Fish, and Land
Climate, Land forms, and Metamorphosis
Sedimentary, Magma, and Climate
Fossils, Land forms, and Climate
What is the force that moves the continents?
Convection Currents in the Mantle
Radiation in the Mantle
Convection Currents in the Outer Core
Conduction in the Mantle
What makes up Earth's lithosphere?
Crust & Lower Mantle
Mantle & Core
Upper Mantle & Crust
Upper Mantle & Core
The layer of Earth that is moving as explained by Wegener in his Theory of Continental Drift.
Thermodynamic Plates
Tectonic Lithosphere
Tectonic Plates
Lithospheric Crust
Originally the Continental drift theory was not well received by other scientist. Why?
The scientific technology to prove the movement in Earth's crust did not yet exist.
Scientist thought Alfred Wegener was a crazy little man
All of the above
Scientists could not explain how the continents were moving
There were glacial scars found on rocks in the deserts of Africa. What are these evidence for?
Africa was once in an area of the Earth that had a very cold climate
Africa has always been near the equator
