What is the meaning lithosphere?
The lithosphere is the solid, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below.
What type of plate is plate A?
Answer: Plate A is an oceanic plate because it is relatively thinner compared to plate B. While Plate B is a continental plate because it is thicker and floats higher than the other plate.
Does the North American Plate consist of continental lithosphere?
It is composed of two types of lithosphere: the upper crust (where the continental land masses reside) and the thinner oceanic crust. As one of the Earth’s original continents, the North American Plate started forming some three billion years ago when the planet was much hotter and mantle convection much more vigorous.
What tectonic plate is Moscow Russia on?
The recent geodynamics of the Far East region of Russia is considered, where three large tectonic plates converge—Eurasian, North American, and Pacific, as well as several microplates—Okhotsk, Bering, and Amurian—have been hypothesized to exist.
Is Japan in the Ring of Fire?
Japan is part of the Pacific ‘Ring of Fire’ which sees intense seismic activity. Japan also has many active volcanos and is often hit by typhoons, the peak season for which is August and September.
What type of plate boundary is North American and Eurasian plates?
divergent boundary
The westerly side is a divergent boundary with the North American Plate forming the northernmost part of the Mid-Atlantic Ridge, which is straddled by Iceland.

What Plate is Canada located on?
North American tectonic plate
The country of Canada is on the northern portion of the North American tectonic plate.Is the South American plate a continental plate?
two of these plates—the continental South American Plate and the oceanic Nazca Plate—gave rise to the orogenic (mountain-building) activity that produced the Andes.
Where is the Indo Australian plate located?
continent of Australia
The Indo-Australian Plate is a major tectonic plate that includes the continent of Australia and surrounding ocean, and extends northwest to include the Indian subcontinent and adjacent waters. It was formed by the fusion of Indian and Australian plates approximately 43 million years ago.
Is the Philippines plate oceanic or continental?
Philippine Sea Plate is an oceanic plate surrounded by subduction zones. The plate is moving northwest at a rate of 6 – 8 cm/year towards the Eurasian Plate. Ranken and Cardwell (1984) showed that the rate of convergence increases southwards along the trench.What type of plate is South America and Antarctic plates?
