What is the process of seafloor spreading?

• Seafloor spreading is caused by the movement of tectonic plates towards each other.

• The process of seafloor spreading involves the formation of new land through volcanic activity.

• New oceanic crust is formed through volcanic activity and then gradually moves away from the mid-ocean ridge.

• Oceanic crust is formed through erosion and then moves towards the mid-ocean ridge.

Explain the significance of mid-ocean ridges in the process of seafloor spreading.

• Mid-ocean ridges are where new oceanic crust is formed, contributing to the process of seafloor spreading.

• Mid-ocean ridges are where old oceanic crust is formed

• Mid-ocean ridges are not related to the process of seafloor spreading

• Mid-ocean ridges have no significance in seafloor spreading

How does plate tectonics contribute to seafloor spreading?

• The movement of tectonic plates has no effect on seafloor spreading.

• Seafloor spreading occurs due to the melting of polar ice caps.

• Seafloor spreading is caused by the gravitational pull of the moon.

• The movement of tectonic plates causes the oceanic crust to spread apart at mid-ocean ridges.

Describe the role of convection currents in the movement of tectonic plates.

• Convection currents in the core cause the movement of tectonic plates.

• Convection currents in the ocean cause the movement of tectonic plates.

• Convection currents in the mantle cause the movement of tectonic plates.

• Convection currents in the atmosphere cause the movement of tectonic plates.

What is magnetic striping and how does it provide evidence for seafloor spreading?

• Magnetic striping is a result of volcanic activity on the ocean floor

• Magnetic striping is caused by the movement of tectonic plates

• Magnetic striping is the alternating pattern of magnetic polarity found in the ocean floor. It provides evidence for seafloor spreading because as new oceanic crust is formed at mid-ocean ridges, the Earth's magnetic field causes the minerals in the crust to align with the polarity of the field, creating the magnetic striping pattern.

• Magnetic striping is a type of rock formation found in the ocean floor

Explain the concept of transform boundaries and their role in crustal deformation.

• Transform boundaries are where tectonic plates move away from each other, causing mountain formation

• Transform boundaries are where tectonic plates move towards each other, causing volcanic eruptions

• Transform boundaries are where tectonic plates remain stationary, causing no geological activity

• Transform boundaries are where two tectonic plates slide past each other horizontally, causing earthquakes and creating fault lines.

What are the characteristics of a subduction zone and how does it contribute to crustal deformation?

• It causes expansion and subsidence of the overriding plate, as well as creating shallow ocean trenches and no volcanic activity.

• It has no effect on the overriding plate, and does not create any geological features.

• It causes compression and uplift of the overriding plate, as well as creating deep ocean trenches and volcanic activity.

• It leads to the formation of new crust and contributes to the stability of the tectonic plates.

Describe the process of subduction and its impact on the Earth's crust.

• Subduction is the process of tectonic plates colliding and forming new crust

• Subduction is the process where one tectonic plate is forced beneath another, leading to the recycling of old crust and the formation of volcanic arcs.

• Subduction is the process of tectonic plates moving away from each other, causing earthquakes

• Subduction is the process of tectonic plates sliding past each other, causing mountain formation

How do transform boundaries contribute to the formation of earthquakes?

• By creating new land through volcanic activity

• By causing the release of built-up stress as tectonic plates slide past each other.

• By increasing the temperature of the Earth's core

• By causing the plates to collide and form mountains

Explain the relationship between subduction zones and volcanic activity.

• Volcanic activity is caused by the movement of tectonic plates

• Subduction zones lead to volcanic activity due to the melting of the subducted plate and the formation of magma.

• Subduction zones cause earthquakes, not volcanic activity

• Subduction zones have no effect on volcanic activity
