crust
A geologist studies the Earth's crust, mantle, continents, and ocean floor. They investigate the composition, structure, and processes of these layers to understand Earth's history and dynamics. Geologists also examine natural resources and environmental implications related to these components.
Evidence for the movement of Earth's continents includes the matching coastlines, similar rock formations and fossils found on different continents, and the distribution of certain plant and animal species across continents that were once connected. Additionally, the discovery of magnetic stripes on the ocean floor, along with the theory of plate tectonics, further support the idea that Earth's continents have moved over time.
No, the lithosphere includes the outer part of Earth's surface which comprises both the land masses (continents) and the ocean floor. It consists of the crust and the upper part of the mantle.
Sea-floor spreading is the process where new oceanic crust is formed at mid-ocean ridges, pushing the existing crust apart. As the crust spreads, it carries the continents on tectonic plates with it, causing the continents to move. This movement is called plate tectonics, and it is responsible for the shifting of continents over geological time scales.
Yes, the ocean floor has features such as mountains, valleys, ridges, and plains that are similar to those found on continents. These features are formed by processes like tectonic activity, volcanic eruptions, and erosion. Additionally, both the ocean floor and continents have ecosystems that support various marine and terrestrial organisms.

A continental shift refers to the movement of continents on the Earth's surface due to plate tectonics. This movement is very slow, occurring over millions of years, and can result in changes to the configuration of the continents and the ocean basins. Examples of continental shifts include the breakup of Pangaea into the continents we see today.
rift zones
Earth's crust is composed of the continents and the ocean floor.
Sea floor spreading provides a way for the continents to move over Earth's surface. Continents are carried by the widening sea floor. The molten rock from a rift cools, hardens, and then moves away in the opposite directions on both sides of the ridges. hope this helps :)
About 71% of the surface of the earth is covered by ocean. That leaves about 29% in the continents. So there is roughly 2.5 times as much ocean as continent.
the final floor
This section of the ocean from floor to surface is called the water column.
