I’ll never find one – no matter where I go,

not even if I went back to mother and father,

the house where I was born and my parents reared me once.

Ah, but much as I grieve for them, much as I long

to lay my eyes on them. Set food on the old soil,

it’s longing for him, him that wrings my heart –

Odysseus, lost and gone!

That man, old friend, far away as he is…

I can scarcely bear to say his name aloud,

so deeply he loved me, cared for me, so deeply.

Worlds away as he is, I call him my Master, Brother!”

describe why rocks found at the bottom of the river are smooth and flat.Please in your own words,My teacher would get mad

Answers

The rocks found at the bottom of a river smooth and flat because those are collides with each other.

Explanation:

At the bottom of the river, the rocks which are found are very smooth and the shape of these rocks are flat because the rocks at the bottom collide with each other.

This results in the chipping off parts of the rocks and this results in the surface of the rock to become smooth and becoming flat. Moreover the sand found at the bottom acts as a sand paper creating resistance and smooth-ens the rocks at the bottom of the river.

Abrasion, which is the physical wearing away of a material by friction, is the process that results in the formation of smooth and flat rocks often found at the bottom of rivers.

What is Abrasion?

Abrasion is the process of rubbing or scraping away a material, by rubbing against a rough surface or causing friction. This type of mechanical weathering can be brought about by a variety of things, including wind, water, snow, and human action. Rock, metal, plastic and wood are some of the materials that may be subject to abrasion.

This may result in material loss and modification of the appearance and texture of the surface. Natural features such as the smoothness of river boulders or the roundness of pebbles on a beach can also be the result of friction. Sandblasting, grinding and polishing are some examples of industrial abrasive applications.

Therefore, Abrasion, which is the physical wearing away of a material by friction, is the process that results in the formation of smooth and flat rocks often found at the bottom of rivers.

A rock is a geological term that refers to solid materials, made up of crystals or grains of one or more minerals. Rock is the main material in the Earth's crust.

Four diagrams of the Earth's crust are shown in the image. All four have three horizons and different forces influence them except A. These forces are caused by the movements of the Earth's lithosphere and are represented by arrows in the direction of movement.

In the case of diagram A, having no arrow means that no force acts on it. Additionally, you can see the three horizons or layers that make up this sample of land.
