The model demonstrates the differences between the types of tectonic plates and the resulting observations in the asthenosphere there are two foremost sorts of tectonic plates: Oceanic and Continental. Continental crust is often fashioned of granite and is typically referred to as sial because of a large amount of silica and aluminum gift. Continental crust is much less dense than the basaltic oceanic crust, sima, which is constructed from silica and magnesium. Due to the fact it's far denser, oceanic crust plunges beneath the continental crust. The department between the 2 layers is known as the Conrad Discontinuity.
Asthenosphere, a sector of Earth's mantle mendacity beneath the lithosphere and believed to be a whole lot hotter and more fluid than the lithosphere. The asthenosphere extends from about 100 km (60 miles) to about 700 km (450 miles) underneath Earth's floor. Cross-section of a tectonic plate.
It's miles a layer of stable rock where the intense pressure and warmth cause the rocks to flow like a liquid. The rocks in the asthenosphere are not as dense because of the rocks in the lithosphere. This allows the tectonic plates within the lithosphere to move around on the planet's floor.
The asthenosphere is the robotically weak and ductile vicinity of the upper mantle of Earth. It lies underneath the lithosphere, between approximately 80 and two hundred km below the surface, and extends as deep as seven-hundred km. But, the decreased boundary of the asthenosphere isn't always well described.

The statement " "Per capita GNI measures average (mean) wealth, not the distribution" means that if only a few people receive much of the GNI, that is not factored in. I hope my answer has come to your help. God bless and have a nice day ahead!
Answer:
A physical characteristic of a place, such as characteristics like climate, water sources, topography, soil, vegetation, latitude, and elevation. Ex: Texas is very hot, there are oceans, and it is 31 degrees north and 99 degrees west.
Explanation:
Solution:
The answer is
Resolution:
They knew that once invoked, the executive benefit would shield Bush from investigations. The Bush Administration invoked executive privileges six times. During each time it had done so, it concerned investigations steaming from the war on terror to meeting with government officials as well requiring members of his team to testify.
A.) Geography can help us prepare for how cities and societies may grow.
