2024年12月16日 · Seafloor spreading is a geological process that explains how new oceanic crust forms at mid-ocean ridges and gradually moves outward. One of the strongest pieces of evidence supporting this theory is found in When scientists drill into the ocean floor, they collect samples of rocks and sediments.

2023年10月20日 · Final answer: Continental plates plunge beneath oceanic plates during a collision in tectonic motion. Explanation: Yes, the statement that continental plates plunge beneath oceanic plates during a collision is correct. This is known as subduction, which is a type of tectonic motion. Subduction occurs when a dense oceanic plate slides beneath a less dense continental plate at a convergent plate ...

Seafloor spreading happens when volcanoes form new crusts, and the old crust spreads apart with the new crust filling in the gap. This helps explain the theory of plate tectonics and continental drift.

Seafloor spreading is the underwater geological process caused by tectonic plate movements at mid-ocean ridges, where new oceanic crust is formed. This process is crucial in shaping the ocean floor and is related to the unique ecosystems surrounding hydrothermal vents.

2017年12月26日 · Seafloor spreading is a geological process that helps explain the movement of tectonic plates and the formation of new oceanic crust. Here are three types of evidence supporting this phenomenon: Age of Rocks: Studies have shown that rocks located near mid-ocean ridges are younger compared to those found near oceanic trenches.

2020年9月11日 · The statement that best describes the cyclic nature of seafloor spreading is 'New oceanic crust is created.' Seafloor spreading is a geological process that occurs at mid-ocean ridges, where tectonic plates diverge.

2019年3月27日 · seafloor spreading is the formation of new areas of oceanic crust, which occurs through the upwelling of magma at midocean ridges and its subsequent outward movement on either side.

2018年8月1日 · If I explore two oceanic plates at a divergent boundary, earthquakes faults ocean formation mountains volcanoes island chains seafloor spreading Location Six: Select two events that you predict will be observed.

2025年1月1日 · Seafloor spreading is a geological process that occurs at divergent boundaries, where tectonic plates move apart. This process is primarily found at mid-ocean ridges, which are undersea mountain ranges. As these tectonic plates separate, magma from the mantle rises to fill the gap, leading to the formation of new oceanic crust.

2017年11月13日 · C. Seafloor spreading: This is a primary piece of evidence that directly supports the theory of plate tectonics. Seafloor spreading occurs at mid-ocean ridges, where new oceanic crust is created by volcanic activity.
