What is necessary for a convection cell to be set up in a fluid?
A. thermal gradient and changes in density
B. thermal gradient
C. changes in density
A. thermal gradient and changes in density
B. thermal gradient
C. changes in density
The correct answer is:
A. thermal gradient and changes in density
A thermal gradient causes differences in temperature within the fluid, which leads to changes in density. These density differences drive the movement of fluid, setting up convection cells.
What evidence did Alfred Wegener use to support his theory of continental drift?
A. Wegener had no evidence, which is why his theory was rejected.
B. coastline fits between different continents, similar rocks and fossils on different continents
C. coastline fits between different continents only
A. Wegener had no evidence, which is why his theory was rejected.
B. coastline fits between different continents, similar rocks and fossils on different continents
C. coastline fits between different continents only
The correct answer is:
B. coastline fits between different continents, similar rocks and fossils on different continents.
Alfred Wegener presented several pieces of evidence to support his theory of continental drift, including the fitting shapes of coastlines, the distribution of similar rock formations across different continents, and the presence of similar fossils in regions that are now separated by vast oceans.
Is this statement true or false?
In a convection cell, cold dense material rises, while hot, less dense material sinks.
A. true
B. false
In a convection cell, cold dense material rises, while hot, less dense material sinks.
A. true
B. false
The statement is B. false.
In a convection cell, hot, less dense material rises, while cold, dense material sinks.
Is this statement true or false?
The plates of the earth’s crust may also contribute to maintaining upper mantle convection.
A. true
B. false
The plates of the earth’s crust may also contribute to maintaining upper mantle convection.
A. true
B. false
The statement is A. true.
The movement of tectonic plates can influence and contribute to the processes of mantle convection in the upper mantle. The interaction of these plates can affect heat transfer and the flow of material in the mantle.
