What is one type of evidence for continental drift mentioned in the document?
Ocean currents
The Continental Puzzle
Mountain ranges
Climate patterns
How would you use the evidence of ancient climates (like glacial deposits in warm climates today) to support the theory of continental drift?
By arguing that climate change is a recent phenomenon.
By suggesting that glaciers can form in any climate.
By explaining that continents have moved from polar to temperate zones.
By stating that the Earth's axis has shifted.
What forms as a result of volcanic activity caused by the subduction of oceanic lithosphere beneath a continent?
Oceanic trenches
Continental volcanic arcs
Mid-ocean ridges
Rift valleys
What happens to the oceanic lithosphere at an oceanic-continental convergent boundary?
It rises to form mountains
It subducts beneath the continental lithosphere
It remains stationary
It transforms into a continental crust
Which of the following is an example of a location where oceanic-continental subduction occurs?
The Himalayas
The Andes
The Mid-Atlantic Ridge
The Great Rift Valley
Which mountain range is found in North America and is shown in the diagram?
Andes Mountains
Appalachian Mountains
Rocky Mountains
Himalayas
Which process occurs first in the formation of a spreading center?
Linear sea formation
Rift valley formation
Upwarping
Oceanic ridge formation
What do rift valleys represent?
Areas of volcanic activity
Deep faulted structures along divergent plate boundaries
Zones of oceanic lithosphere destruction
Elevated zones on the ocean floor
What significant event happened 50 million years ago according to the diagram?
India collided with Asia
Australia began to separate from Antarctica
The Atlantic Ocean formed
Europe and Asia merged
According to the plate tectonics theory, what is the uppermost mantle and the overlying crust collectively known as?
Asthenosphere
Lithosphere
Mesosphere
Atmosphere
According to the continental drift hypothesis, the presence of similar fossils in South America and Africa supports which scientific idea?
Animals easily and frequently travel from Africa to South America.
Species of animals probably traveled between continents on natural rafts (such as trees destroyed in tsunamis).
Land bridges once existed that connected the continents.
South America and Africa were once connected together.
What geological feature is formed at an oceanic-continental convergent boundary?
Mid-ocean ridge
Trench
Rift valley
Hotspot
Which continents were part of Pangaea 250 million years ago?
Only North America and Europe
All major continents
Only Asia and Africa
Only South America and Antarctica
What occurs at divergent boundaries within a continent?
The landmass may split into two or more smaller segments, forming a rift.
The landmass remains unchanged.
The landmass collides with another continent.
The landmass sinks into the ocean.
At which type of plate boundary do tectonic plates collide, often causing mountain formation?
Convergent boundary
Divergent boundary
Transform fault boundary
Rift valley
What type of plate boundary is characterized by two tectonic plates sliding past each other horizontally?
Convergent boundary
Divergent boundary
Transform fault boundary
Subduction zone
What geological feature is formed at a spreading center?
Mountain range
Oceanic ridge
Trench
Plateau
What occurs at a convergent boundary?
Two plates move apart
Two plates move together
Two plates grind past each other
Plates remain stationary
What major geological event occurred 200 million years ago?
The formation of the Himalayas
The rifting that led to the Atlantic Ocean
The collision of India with Asia
The separation of Australia from Antarctica
What geological feature is formed at an oceanic-oceanic convergent boundary?
Volcanic island arc
Mountain range
Rift valley
Mid-ocean ridge
