A) A deep ocean trench
B) A mid-ocean ridge
C) A hot spot
The most likely answer is B) A mid-ocean ridge. This is because a mid-ocean ridge is formed when two tectonic plates move apart and molten rock from the Earth’s mantle rises up to fill the space. The molten rock then cools and forms new crust.

Q: What is the result of mantle convection?
A: Mantle convection is the result of heat transfer within the mantle of a planet. This heat transfer can happen through either conduction or convection, but mantle convection is generally thought to happen through convection.
Q: What heat processes are involved in mantle convection?
A: Mantle convection is driven by heat from the Earth’s core. The mantle is heated by the Earth’s hot core, and the heat is transferred to the mantle by convection. The mantle then transfers the heat to the crust by convection.
Q: How does convection in the mantle cause changes to the crust?
A: The mantle is the layer of the Earth below the crust. It is made up of hot, solid rock. The heat from the mantle causes the rock to circulate in a process called convection. The hot rock rises up and the cooler rock sinks down. This movement of the mantle can cause changes in the crust.
Q: What are the types of mantle convection?
A: There are two types of mantle convection: hot spot and plate tectonics. Hot spot mantle convection is caused by heat rising from the Earth’s core, while plate tectonics is driven by the interaction between the lithosphere and the mantle.
