No. Mid oceanic ridges are the places where new oceanic crust are forming.
False. The Earth's crust is generally thicker under high mountains due to the accumulation of material from geological processes such as plate tectonics and volcanic activity. In contrast, the crust is thinner under oceanic regions.
false
Plate tectonics is actually causing the Atlantic Ocean to widen, as the plates are moving apart in a process known as seafloor spreading. This creates new oceanic crust and widens the Atlantic Ocean basin over time.

False. The Earth's radius and surface area do not increase as new oceanic crust is formed at mid-oceanic ridges. Instead, the creation of new crust at mid-oceanic ridges is balanced by the destruction of older crust at subduction zones, maintaining the overall size of the Earth.

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.
True. Continental crust is primarily composed of lighter rocks such as granite, which are less dense than the basaltic rocks found in oceanic crust. This is why continental crust is thicker and less dense than oceanic crust.
False. The crust is actually thinnest under ocean basins due to the presence of dense oceanic crust. Under high mountains, the crust tends to be thicker due to the compression and folding of rock layers.
False. The crust is actually thinnest under oceans, not high mountains. Mountain ranges are typically where the crust is the thickest due to the intense tectonic activity that creates them.
True. Magnetic stripes on the ocean floor are created by alternating bands of magnetic polarities in the oceanic crust. These stripes are evidence of seafloor spreading where new crust is formed at mid-ocean ridges, pushing older crust away. Subduction zones are where older crust sinks back into the mantle.
False. Continental crust is mostly composed of less dense granite and granodiorite rocks, which contain minerals such as quartz, feldspar, and mica. Basaltic rocks are more characteristic of oceanic crust.
Yes; at divergent/constructive boundaries, plates move apart and new oceanic lithosphere forms.
