What is the name for the process by which new oceanic crust is formed at divergent plate boundaries?
A) Subduction
B) Seafloor spreading
C) Continental drift
D) Convection
B) Seafloor spreading
What is a subduction zone?
A subduction zone is a region where one tectonic plate is forced beneath another plate into the mantle.
What type of boundary is the San Andreas Fault in California?
A) Convergent boundary
B) Divergent boundary
C) Transform boundary
D) Subduction zone
C) Transform boundary
What is the name for the process of one tectonic plate sliding beneath another into the mantle?
A) Rifting
B) Subduction
C) Seafloor spreading
D) Convection
B) Subduction
Where are most earthquakes and volcanic eruptions located?
A) Mid-ocean ridges
B) Transform boundaries
C) Convergent boundaries
D) Divergent boundaries
C) Convergent boundaries
How do tsunamis differ from regular ocean waves?
Tsunamis are typically much longer in wavelength and travel at higher speeds compared to regular ocean waves.
What is the primary cause of tsunamis?
Tsunamis are primarily caused by underwater earthquakes, volcanic eruptions, or landslides.
Where are most divergent plate boundaries located?
Most divergent plate boundaries are located along mid-ocean ridges, such as the Mid-Atlantic Ridge and the East Pacific Rise.
Where are tsunamis most likely to occur?
Tsunamis are most likely to occur in the Pacific Ocean's "Ring of Fire" due to its high level of tectonic activity.
What occurs at transform plate boundaries?
Plates move past each other.
What type of plate boundary is associated with the formation of the Himalayan Mountains?
A) Convergent boundary
B) Divergent boundary
C) Transform boundary
D) Subduction zone
A) Convergent boundary
What is Pangaea?
Pangaea was a supercontinent that existed about 300 million years ago and eventually broke apart to form the continents we have today.
What causes earthquakes?
Earthquakes are caused by the sudden release of energy along faults in the Earth's crust, resulting in seismic waves.
What happens at divergent plate boundaries?
At divergent plate boundaries, tectonic plates move away from each other, leading to the formation of new oceanic crust and rift valleys.
The movement of tectonic plates is primarily driven by which of the following processes?
A) Mantle convection currents
B) Atmospheric pressure
C) Ocean currents
D) Solar radiation
A) Mantle convection currents
What are tectonic plates?
Tectonic plates are large pieces of the Earth's lithosphere that move and interact with each other.
Who proposed the theory of continental drift?
Alfred Wegener proposed the theory of continental drift in the early 20th century.
What evidence supports the theory of continental drift?
Evidence includes the fit of continents, identical fossils found on different continents, matching geological features across continents, and similar rock formations.
What are the three main types of plate boundaries?
The three main types of plate boundaries are divergent boundaries, convergent boundaries, and transform boundaries.
What occurs at convergent plate boundaries?
At convergent plate boundaries, tectonic plates move towards each other, leading to the formation of mountain ranges, volcanic arcs, and deep ocean trenches.
What does the evidence of fossil records in continental drift proves?
Fossils of similar organisms found on different continents suggest that these continents were once connected and that they drifted apart over time.
What is a tsunami?
A tsunami is a series of ocean waves caused by the displacement of a large volume of water, usually from an underwater earthquake, volcanic eruption, or landslide.
Where is the "Ring of Fire" located, known for its high seismic and volcanic activity?
A) Atlantic Ocean
B) Indian Ocean
C) Pacific Ocean
D) Arctic Ocean
C) Pacific Ocean
What is the Richter scale used for?
The Richter scale is used to measure the magnitude of earthquakes.
Which of the following types of boundaries is associated with the formation of fold mountain ranges?
A) Convergent boundaries
B) Divergent boundaries
C) Transform boundaries
D) Subduction zones
A) Convergent boundaries
