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.
A. The deaths of all plants and marine life in the area.
It's because of the lack of oxygen since eutrophication often leads to algal bloom which in turn blocks the radiation and doesn't let oxygen to pass through it
Explanation:
Stomata are small pores found on the leaves of plants, through them occur an exchange of water and gases and <em>when moisture leaves the plants, a process called transpiration happens, this leads to a process similar to the evaporation.</em> Additionally, <em>plants release water vapor as a product of photosynthesis and help to prevent soil erosion by elevating groundwater.</em>
