Why is the Earth a sphere?

Hello My Dear Friend!

 <span>Large bodies of material will naturally become approximately spherical in shape because gravity pulls everything towards the centre of mass, and the best shape for getting all the particles that make up the body (like all the particles of rock and iron the earth is made of) close to the centre is a sphere. It's the lowest energy configuration, and that's what everything strives to be in. 

So, opposing this gravitational force is the ability of the material that makes up the body to support itself. Hence why on the hard surface of the earth, we can still have mountains like the Himalayas - gravity at the surface isn't strong enough to crush these flat. 

The rotation of the earth causes it to assume a slightly squashed shape too, due to centrifugal force, which pushes material outwards - more so at the equator, which is furthest from the axis of rotation. Any rotating object will have some degree of squashing as a result.

It is a sphere to be precise.

Because of the omnidirectional nature of the gravitational attraction, mass tends to form spheres in the macro scale of planets and similarly massive celestial bodies.

Compare the similarities and differences between natural selection and artificial selection
AysviL [449]

Similarities: Natural Selection and Artificial Selection both result in the alteration of the gene pool. It can also change phenotypes of different species'.

Differences: Artificial Selection is when a specific trait is not wanted, and so it is not bred.

For example, humans did not like how yellow peas looked. They liked the healthy looking green better. So, they killed the yellow peas, and bred the green peas with other green pea plants, and right now it is almost completely out of our gene pool.

Natural Selection is when something naturally occurs, such as a natural disaster, famine, plague, invasive species introduction.

For example, if 10 camels lived in a desert, but one of them didn't have as good of a metabolism and stayed full longer, then that one would survive, while the others might not.

The growth of a population of sparrows accelerates with each generation. the chances of dying are about the same for these sparr
Paladinen [302]

Answer:

Exponential growth and a type II survivorship curve

Explanation:

  • Firstly we need to understand what exponential growth is, it is the type of growth in which population of any specie increases at a tremendous rate, constantly. In this type of growth, the increase is an exponential function of time for example, 2 reproduce to form form, four to sixteen and so on.

Population survivorship curves are simply the graphs representing increase in population with respect to time. There are three types of population survivor ship curve, Type I, Type II and Type III.

  • <u>In Type II survivorship curve,</u><u> </u>there is a constant dying rate of individuals of population with respect to time.

Now lets come back towards question, where two characteristics of the population are mentioned,

  1. Exponential growth of a population of sparrows with each generation.
  2. Constant dying rate

<em>This clarifies that </em><u><em>Exponential growth and a type II survivorship curve</em></u><em> is the best option representing the said scenario.</em>

Hope it help!
