How does an understanding of plate tectonics help us?
It helps us understand the global distribution of Fold Mountains
Plate tectonics explains the movement of the Earth’s lithosphere.
Fold Mountains are formed when continental plates collide. True or False?
TRUE
This collision leads to the buckling and uplifting of the Earth’s crust.
The Caladonian Fold Mountains in Ireland were created when which two plates collided?
Eurasian and American plates
This collision occurred 400 million years ago.
Folding can also happen when oceanic and continental plates collide. True or False?
TRUE
This process contributes to the formation of mountain ranges like the Andes.
The Andes in South America were created by the collision of which plates?
Nazca and South American Plates
This collision is still ongoing.
What are the most famous Fold Mountains studied?
The Himalayas
They were created by the collision of the Eurasian and Indian-Australian plates.
The first stage in the formation of Fold Mountains involves the build-up of sediment on _______.
ocean floors
This sediment is a result of weathering of continents.
Over time, sediment compacts and cements into sedimentary rock such as _______.
Limestone
This process is crucial in the formation of Fold Mountains.
What drives plate movement on the Earth’s crust?
Powerful convection currents from the mantle
These currents slide the lithosphere around on the weak asthenosphere.
Convection currents can be seen as the engine that drives _______.
plate movement
They are responsible for the dynamic nature of the Earth’s surface.
As plates move towards each other, the sedimentary bedrock of each plate _______.
buckles and is forced upwards
This process leads to the formation of mountains.
The theory of plate tectonics can be proven by the presence of marine fossils high up in the _______.
Himalayas
These fossils indicate that ancient sea floors were uplifted during plate collisions.
The Indian plate began its northwards movement _______ million years ago.
70
It continues to push against the Eurasian plate today, contributing to the growth of the Himalayas.
The Himalayas are still _______ in height due to ongoing plate movement.
growing
This growth is a result of the continuous collision between the Indian and Eurasian plates.
