How are plate tectonics and continental drift similar?
Plate tectonics is Wegener theory of continental drift reworked. The force needed to move the continents is proposed to be convection currents in the mantle. The continents are seen as part of large plates of crust that are moved by the convection currents in the mantle.
What is the relationship between the continent and Earth’s plates?
What is the relationship between the continent and earth’s plates? The continent is part of a plate. The continent is next to but is not part of a plate. The continent is on top of a layer of water that is above a plate.
What is the relevance of the movements of plates to the formation and deformation geologically?
Answer: The relevance of the movements of plates to the formation and deformation geogically is that it creates mountains, ridges, volcanoes and rifts which helps circulate nutrients essential for life.
How many plate tectonics are there?
how many tectonic plates are there? There are major, minor and micro tectonic plates. There are seven major plates: African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American.
What are two bad things about plate tectonics?
Two bad things that can happen as a result of plate tectonics are: volcanoes and earthquakes.
Which tectonic plate is most stable?
Ancient plates and cratons Cratons are the oldest and most stable parts of the continental lithosphere and shields are the exposed area of a craton(s).
How old are tectonic plates?
around 3 billion years ago
Why do we need tectonic plates?
Why plate tectonics is important. These are the Earth’s major tectonic plates. USGS Plates cover the entire Earth, and their boundaries play an important role in geologic happenings. The movement of these plates atop a thick, fluid “mantle” is known as plate tectonics and is the source of earthquakes and volcanoes.
