How does seafloor spreading explain continental drift?
Seafloor spreading is caused by two plates moving apart. This is caused by plate tectonics. Continental drift is also caused by plate tectonics. Therefore, we can conclude that continental drift is related to seafloor spreading. When the plates move, it carries the continents with it, and thus the continents drift away from each other.
What was the primary force that causes the seafloor to spread and continents to drift?
The primary force driving seafloor spreading and continental drift is mantle convection. Heat from Earth's core causes the mantle to circulate, creating convection currents that move tectonic plates, leading to the spreading of the seafloor and movement of continents.
How is seafloor spreading different than continental drift?
Seafloor spreading is the process where new oceanic crust is formed at mid-ocean ridges and then moves apart, while continental drift refers to the movement of continents on the Earth's surface. Seafloor spreading is one mechanism that helps drive the movement of continents as part of plate tectonics.
Why the seafloor exhibits magnetic reversal but the continents did not?
The seafloor exhibits magnetic reversals because new oceanic crust is continuously forming at mid-ocean ridges, capturing the direction of Earth's magnetic field at the time of its formation. In contrast, the continents are made of thicker and older crust, which does not record magnetic reversals as readily as the rapidly-formed seafloor crust.
What type of sediment dominates the seafloor adjacent to continents?
Terrigenous sediment, which consists of material eroded from the continents such as sand, silt, and clay, dominates the seafloor adjacent to continents. This sediment is transported to the ocean by rivers, wind, and glaciers, and accumulates near the continental margins. It is one of the most common types of sediment found in the world's oceans.

What is the idea that continents have moved horizontally through the seafloor to their current locations?
seafloor spreading by Harry Hess
What does seafloor spreading have to do with the theory of continental drift?
Seafloor Spreading helped move the Continents to their current location.
What movement causes continents to grow outward?
The movement that causes continents to grow outward is called seafloor spreading. This occurs at mid-ocean ridges where tectonic plates diverge, allowing magma to come up and create new seafloor. As new seafloor forms, it pushes the continents on either side further apart, leading to the growth of the continents.
What caused the continents to rise from the seafloor millions of years ago?
floaties
Are all plate boundaries located along the margins of continents?
No. Many plate boundaries are on the seafloor far from continents and several are well within continents.
What primary force that causes the seafloor to spread and continents to drift?
Geothermal Drift.
What was the primary force that causes the seafloor to spread and continents to drift?
The primary force driving seafloor spreading and continental drift is mantle convection. Heat from Earth's core causes the mantle to circulate, creating convection currents that move tectonic plates, leading to the spreading of the seafloor and movement of continents.
Why can't someone feel the seafloor spreading?
We can't feel seafloor spreading because the ocean is super deep that the continents will not shake or burst in somewhat actions.
How are rocks near continents different from rocks found near centers of seafloor spreading?
Rocks near continents are typically older and more varied in composition, while rocks near centers of seafloor spreading are younger and primarily composed of basalt. Continental rocks may have undergone more geological processes, leading to greater diversity in mineral content and structure, whereas seafloor rocks are usually basaltic due to the solidification of magma from undersea volcanic activity.

Seafloor spreading is one mechanism that helps drive the movement of continents as part of plate tectonics.
What role did seafloor spreading play in arranging the continents as they are today?
Seafloor spreading is the process by which new oceanic crust is created through volcanic activity at mid-ocean ridges. As this new crust forms, it pushes the existing crust apart, which in turn causes the continents to move. This movement of the tectonic plates, driven by seafloor spreading, plays a significant role in shaping the arrangement of continents as they are today through the theory of plate tectonics.
