False.
False. The Earth's radius and surface area are not increasing to accommodate new oceanic crust. Instead, the process of seafloor spreading at mid-ocean ridges involves the creation of new oceanic crust, which is balanced by the destruction of crust at subduction zones, maintaining the Earth's overall surface area.
No, Earth's radius and surface area are not increasing to accommodate new oceanic crust. The process of seafloor spreading at mid-ocean ridges is balanced by subduction, where older crust is recycled back into the mantle. This maintains the overall size of Earth and its surface area.
No, the size of the Earth is not increasing due to oceanic crust being produced. The creation of oceanic crust at mid-ocean ridges is balanced by its destruction at subduction zones, resulting in a process known as plate tectonics where the Earth's surface remains relatively constant in size.
The two types of crust that cover the Earth's surface are oceanic crust, which is thinner and denser, and continental crust, which is thicker and less dense. Oceanic crust is mainly composed of basalt, while continental crust is primarily composed of granite.
Assuming the depth of the layer is restricted to between 1000mb and 500mb, and increasing with time, it is almost certain that the surface temperature will remain constant, thus not increasing or descreasing.

Oceanic crust covers about 60% of the Earth's surface.

The largest layer of Earth's surface is the crust, which is divided into oceanic and continental crust. The continental crust is thicker and less dense than the oceanic crust, covering about 40% of the Earth's surface.
