What is the asthenosphere's temperature? What is the Earth's average surface temperature? What percent of the Earth is the mantle? How far down is the Earth's mantle? What is the density of the Earth's mantle? How wide is the Earth's mantle?
It is mostly made up of iron(铁) and almost as hot as the inner core.The next part is the mantle(地幔). It cir-cles the outer core and is about 2, 900 kilome-ters thick, making it the earth's thickest part.The mantle is mostly made up of rock, but it also includes some ...
Question: What is the temperature at the bottom of the ocean? Ocean Temperatures: The ocean is made up of layers. The topmost area, which receives the most sunlight, has the warmest temperatures. Each layer below the surface becomes incrementally cooler the deeper you go. ...
What is the temperature of the Earth's mantle? What layers of Earth make up the lithosphere? What is the region where the lithosphere meets the mantle? What theory of plate movement involves magma rising? What is a tectonic cycle?
It is mostly made up of iron(铁)and almost as hot as the inner core.The next part is the mantle(地幔). It circles the outer core and is about2,900 kilometers thick, making it the earth's thickest part. The mantle is mostly made up of rock, but it also includes some magma(...
The motion of the Earth's mantle is controlled in part by how mantle minerals respond to changes in temperature and pressure. The chemical and physical shifts that minerals undergo as they are heated and squeezed cause some to sink down toward the core and others to rise up toward the ...
Theselayers are called the inner core, the outer core, the mantle, and thecrust.The inner core is at the center of the earth. It's a solid sphere ofhot metal, about 70 percent the size of our moon. The temperature ofthe inner core (which comprises the metals nickel and iron) can ...
You cannot see the mantle of the earth except for the rare times that lava runs out of volcanoes. It is the layer of the earth that lies beneath the surface. The temperature is unimaginably hot and no living creatures can live in the earth's mantle.
by latitude and other geographic factors, the long-term average global climate is quite stable during interglacial periods,[6] and variations of a degree or two of average global temperature have historically had major effects on the ecological balance, and on the actual geography of the Earth.[...
Earth is the planet of life. Running, crawling or flying, life abounds everywhere.地球是一个满是生命的星球。奔跑着的、爬行着的或飞翔着的，到处都是生命。But for all this beautiful diversity to have proliferated, Earth has had to provide a favourable environment for around four billion years. ...
