The Earth is made up of three layers. In the centre is the core, which is as big as the Mars and has a high 1 of over 7,000˚C. 2 the core is a thick layer called the mantle, 3 lower part is solid rock, 4 portion is molten rock called the magma. Floating on top of t...
In plate tectonics, Earth's outermost layer, or lithosphere—made up of the crust and upper mantle—is broken into large rocky plates. These plates lie ontop of a partially molten layer of rock called the asthenosphere. What is it called when tectonic plates collide? If two tectonic plates ...
The crust of the Earth is the top layer, the surface of the Earth. The layers under the crust are the mantle and the core. The heat and pressure increase significantly under the crust of the Earth where there is magma.Answer and Explanation: ...
They have essentially sliced up the Earth into layers to better focus studies on these layers and how these layers interact with each other. The lithosphere and asthenosphere are two such layers.Answer and Explanation: The lithosphere is the hard layer that includes the crust (what we know as ...
Some plates carry islands or continents, others form the seafloor. All are slowly moving because the plates float on a denser semi-liquid mantle, the layer between the crust and Earth’s core. The plates have edges that are spreading ridges (where two plates are moving apart and new ...
Geologic evidence shows that southern African has been slowly rising for the past 100 million years, yet it has not experienced a tectonic collision for nearly 400 million years.The explanation may be in Earth's mantle, the layer of rock underlying the tectonic plates and extending down over 1...
plates float on a denser semi-liquid mantle, the layer between the crust and Earth’s core.The plates have edges that are spreading ridges (where two plates are moving apart and new seafloor is being created), subduction zones (where two plates collide and one plunges beneath the other), ...
【小题2】 the core is a thick layer called the mantle, 【小题3】 lower part is solid rock, 【小题4】 portion is molten rock called the magma. Floating on top of the magma is the Earth’s rocky crust.The crust is made up of tectonic plates. These huge plates are moved slowly by...
The oceanic crust is the layer of earth beneath the ocean. It is composed of the upper oceanic crust and the lower oceanic crust, and is the top layer of the lithosphere. The continental crust is a layer of rock about 40 km thick which makes up all the continental land mass of t...
What are the countries found on Eurasian Plate? How many glaciers in Antarctica? How many glaciers are in Antarctica? What is the West Antarctic Ice Sheet? What countries are most vulnerable to climate change? What can countries do to help the ozone layer recover? What sea surrounds Antarctica...
