how does erosion and mass wasting alter the surface of the earth? In what way do they pose a threat to mankind?​

Answers

Answer 1

Answer:

Erosion is distinct from weathering, in which chemical and physical processes simply break down larger pieces of rock into smaller ones. In erosion, the portions of Earth affected are moved from their original location by forces exerted by gravity, wind, flowing water or some combination.

mark me as brainliest if u find the answer helpful

Answer 2

Based on geographical evidence, erosion and mass wasting can alter the surface of the earth in many ways, some of which include:

Causing degradation of rocks and mountains.

Affecting the shape and structure of valleys and ocean floors which may lead to hilly and steep areas.

It can also affect the rate of rivers, streams, and groundwater flow, among others.

Both erosion and mass wasting can pose a threat to mankind in many ways, such as:

Causing landslides, mudslides, etc.

They affect water potability features.

They strip forest covers.

They affect water habitat and wildlife, a vital source of food and materials for mankind, etc.

Erosion can be caused as a result of water, wind, gravity, or ice. It removes and transports surface materials from one place to another, causing a change in slope and gradient of the land surface.

Mass wasting is the transportation of rocky materials downslope largely by the force of gravity.

Hence, in this case, it is concluded that erosion and mass wasting are natural occurrences that need to be prepared against.

Describe the characteristics of the Nile River and the river’s importance to the people of Egypt. Write a paragraph of at least 5 complete sentences.


plz help :)

Answers

Answer:

The Nile is the longest river in the world, passes through East and Northern Africa, is the only source of freshwater in northeastern Africa, and it is crucial for agriculture.

Explanation:

The Nile River is the longest river in the world, and one of the rivers with the biggest water volume. This river starts its flow in the highlands of Eastern Africa and in a roughly south-north direction moves toward the Mediterranean Sea where it ends its flow. The Nile is actually the only river and only source of freshwater in Egypt.

Egypt is the country that is the most dependent on the Nile. Not just that the Nile is the only source of freshwater, but it is also crucial for traveling and transportation in the interior, as well as for agriculture. Since the river has a slow flow in a lowland area through Egypt, traveling, and transportation through it is very easy and economically the most justifiable. Agriculture depends exclusively on the water of the Nile and the fertile sediments along its shores.

what is an impact of river rejuvenation on farming activities​?

Answers

Explanation:

In geomorphology a river is said to be rejuvenated when it is eroding the landscape in response to a lowering of its base level. The process is often a result of a sudden fall in sea level or the rise of land. The disturbance enables a rise in the river's potential energy, increasing its riverbed erosion rate. The erosion occurs as a means for the river to adjust to its new base level

India is facing its worst water crisis in four decades. At least 54 percent of the sub-continent has turned into a water-stressed dust bowl with many rivers rapidly drying up. Experts opine that by 2025, the country will be facing an acute water crisis if no preventive measures are taken today.

To mitigate the water crisis, Gurudev Sri Sri Ravi Shankar has inspired The Art of Living community to revive lost rivers in various parts of India and other water bodies such as ponds, wells, canals and temple tanks.

The River Rejuvenation Project, which started in 2013 with the aim to provide a long-term and lasting solution, has reviving 43 rivers in four states (Maharashtra, Karnataka, Tamil Nadu and Kerala), benefitting 5,084 villages and 7 million + people benefited.

With meticulous planning and consistent efforts, results have come in: several rivers and other smaller bodies in these states have started flowing once again.

An impact of river rejuvenation is that it leads to increased produce due to the fact that it supplies farmlands with water.

What is river rejuvenation?

This is a situation where there is an eroding of water due to the fact that the water in the rivers have become higher than their base level.

When this is the case they help to provide farmlands with water which are useful to plants.

The Sun's gravity, of the force, keeps the planets from floating off into space. Thus, option (b) is correct.

What is planet?

The term “planet” refers to a large celestial body that orbits around the sun, but the sun is a fixed point in place. The planets are different sizes, as smaller planets are Earth, Mercury, Mars, and Venus. The larger gas giant planets are Jupiter, Uranus, Neptune, and Saturn.

The Sun's gravity plays a major role in the planets' tendency to drift towards space. The orbits are established and maintained by the combined effects of the sun's gravity, that of the planets, and inertia. The Sun and Planets are separated by Gravity, yet are Pulled Together by it. The high level was caused by the heat of the sun. Principal cause: gravity.

As a result, the Sun's gravity, of the force, keeps the planets from floating off into space. Therefore, option (b) is correct.

Explanation:

Example question: How long has it taken for the soil in this place to form?

Geologic Evidence:

Radiometric dating is a technique used to estimate the absolute (numerical) age of geological materials such as rocks, minerals, or organic matter, which is achieved from radioactive isotopes.

The procedure consists of measuring in what proportion the parent isotope and its descendants are present, of which the period of disintegration has already been studied previously. For this, the following equation is used:

                                   t = (1 / λ). Ln (1 + D / P)

Where:

t = the age of the rock

λ = decay constant

D = number of atoms of the daughter isotope within the sample

P = amount of parent isotopes within the sample

The oceanic crust is the high - level network of the ocean and is also known as tectonic plates. The age, breadth, and density of the oceanic crust increased on the mid-ocean ridge. Approximately 120 million years ago in the age of the oldest oceanic crust. The age of earth's lithosphere is roughly 3.2 billion years.

which human action can level the moutain plz i will give brainliest

Answer:

i. Mining activities

ii. Constructions works

iii. Intense mechanized farming

Explanation:

Human activities have been significantly known to have affected the physical environment around us. A mountain is one of the several physical features that abound on our planet earth. They are topographic features with great elevations above surrounding areas.

Some of the human activities that can level mountains are:

Mining activities: In our drive to make society better and to improve standard of living, minerals held-bound in rocks are explored for their benefits. The process involves large scale earth moving activities by which important ores can be removed. Most of them often lead to the leveling of mountains. Construction works: Government can decide to build a railroad or highway through a mountainous region, this often leads to earthmoving and blasting of impeding obstructions. Most of the obstructions are usually mountains. Intense mechanized farming: terrace farming along mountains slope can increase the rate of weathering if not properly managed. This often wears off a mountain gradually. After several years, a towering peak might have been reduced to a level ground.
