Wilson Cycle and Geological Features

The video tutorial introduces the Wilson Cycle, a geological concept describing the opening and closing of oceans due to plate movements. It explains the cycle's phases, starting with continental rifting and the formation of new oceans, followed by the closing phase involving subduction and the creation of orogenic phases. The tutorial also highlights the significance of these processes in shaping Earth's surface and their implications for hydrocarbon resources. A fun exercise is provided to reinforce understanding.

Who introduced the concept of the Wilson Cycle?

• James Hutton

• Harry Hess

• John Tuzo Wilson

• Alfred Wegener

What geological feature is formed during the initial phase of the Wilson Cycle?

• Volcanic islands

• Mountain ranges

• Continental rifting

• Ocean trenches

What is the primary cause of continental rifting in the Wilson Cycle?

• Erosion by water

• Thermal bulge from hot magma

• Tectonic plate collision

• Volcanic eruptions

Which of the following is a potential disadvantage of mid-ocean ridges?

• Formation of new land

• Destruction of petroleum environments

• Increased volcanic activity

• Creation of new ecosystems

Which ocean is an example of a juvenile ocean in the Wilson Cycle?

• Atlantic Ocean

• Pacific Ocean

• Indian Ocean

• Red Sea

What happens to oceanic plates during the closing phase of the Wilson Cycle?

• They form new continents

• They subduct under continental plates

• They remain stationary

• They become lighter

What geological feature is formed when two continental blocks collide?

• Mountain ranges

• Ocean basins

• Deep-sea trenches

• Volcanic islands

What is the significance of trenches in the Wilson Cycle?

• They are areas of high volcanic activity

• They are formed during continental rifting

• They indicate subduction zones

• They are sites of new ocean formation

In the fun exercise, what is the speed at which the blocks move apart?

• 4 cm per year

• 2 cm per year

• 6 cm per year

• 8 cm per year

What is the circumference of the Earth assumed in the fun exercise?

• 60,000 km

• 48,000 km

• 40,000 km

• 50,000 km
