Answer:
4.54 km of earth's crust lies within mantel.
Explanation:
- Earth's continental crust is made of igneous, metamorphic, and sedimentary rocks and is composed of SIAL elements. The continental crust is made of various layers and has a density of 2.83 g/cm, while the oceanic crust is about 2.9 g/cm.
- The ontientla crust has usual thickness of 40 km (25 miles) thick and floats or rests on upper mantel or i.e the asthenosphere. While other parts of it lies within the mantel the depth of the continental crust ranges to 100 km,
- where r/25 = 2.7 / 3.2
- r/25 = 0.82
- r= 0.82 x 25
- r= 20.46
- 25 - 20.46 is 4.54 km.
Varves are best developed near glaciers because they represent light colored layers of coarser material deposited in the summer when the streams issuing from glaciers have more energy to erode coarser material compared to the fine silts and clay of the winter months when there is very little flow and very little erosion. They mostly occur in glacial lakes.
Tectonic plate movement is run by convection of mantle currents.
