How does cliff collapse affect the environment

1 answer:

5 0

A cliff collapse could affect the environment by exposing new rock (previously covered by the cliff) to the elements, which could result in runoff of a different nature when it rains. Additionally, the cliff would collapse upon whatever life/features existed at the base of the cliff. One of the most drastic effects could be the shaking of the earth. Cliff failures can result in earthquakes or, if the cliff collapses into a large body of water, massive tsunamis which radically impact coastal environments.

35. What factor primarily controls the viscosity, and therefore the explosiveness of a magma? A. Dissolved gases B. Pressure C.

Rasek [7]

Answer:

E. Mineral content

Explanation:

Viscosity is an internal property of a fluid that offers resistance to flow, the nature of volcanic eruptions is highly dependent on magma viscosity and also on dissolved gas content (dissolved gases become trapped by thick magma and the magma chamber begins to build pressure).

The viscosity of magma is controlled by the size of the molecules that comprise it.

<em>Felsic lava contains elements of small size (sodium and aluminum), these elements form polymers and large crystalline macromolecules like silica, the more extensive silicate chain molecules the more viscous the magma becomes, this happens because larger molecules have stronger intermolecular bonds preventing movement and spreading. </em>

Mafic and ultramafic lava, on the other hand, have lower viscosities, also contain lower quantities of silica and aluminum and are rich in magnesium oxide, which does not form large molecular structures, therefore lava flows smoothly, unrestricted by intermolecular forces.

I hope you find this information useful and interesting! Good luck!

Nana76 [90]

Our lives and economies depend on energy from the sun and natural resources and natural services provided by the earth.

Humans depend on Earth's land, ocean, atmosphere, and biosphere for many different resources, including air, water, soil, minerals, metals, energy, plants, and animals.

<h3>How does economic growth depend on natural resources?</h3>

Natural resources have a double-edge effect on economic growth, in that the intensity of its use raises output, but increases its depletion rate.

Natural resource is a key input in the production process that stimulates economic growth.

<h3>What are types of natural resources?</h3>

Any natural substance that humans use can be considered a natural resource.

Oil, coal, natural gas, metals, stone and sand are natural resources. Other natural resources are air, sunlight, soil and water. Animals, birds, fish and plants are natural resources as well.
