How does wind transport sand grains

Please answer please. I am in need of your help. NASA says the sun’s gravitational force keeps the planets in orbit, why do astr

Black_prince [1.1K]

$f_{gravity(sun)} = \frac{ g \times m_{sun} m_{astronaut} }{ {(distance \: to \: sun)}^{2} }$
$f_{gravity(earth)} = \frac{ g \times m_{earth} m_{astronaut} }{ {(distance \: to \: earth)}^{2} }$

me
consider the mass of the earth and the mass of the sun. then consider the distance between the astronaut and the sun.

you will see that the force of the Earth's gravity is much greater due to the formula above as the very large distance from the sun

Do you think migration was a voluntary move or involuntary? Why?

shtirl [24]

Answer:

People who flee persecution and violence in their own country are considered asylum seekers while the people who decide to move to another country in order to seek employment and better life opportunities are considered migrants. Migrants can be legal, moving threw documentation. Migrants are usually people with a strong resources in order to prepare their journey and arrival in the country of the destination. They save money, they gather the information about the trip and the destination and about the potential employment there, like how mast Europians or Asians come to america. They speak to friends and family at the destination who will help them upon arrival. They may speak to travel agents, potential employers at destination or middlemen of different sorts. They may try to learn the language of the destination country. In short, migrants clearly make decisions and take up the actions in order to prepare for their migration. This does not necessarily mean their migration is voluntary. The reasons for leaving their country of origin may have to do with circumstances that are beyond their the control. Migrating is not a decision taken easily, it involves high costs. They may do this to help family

Valentin [98]

Answer:

Terrigenous

Explanation:

The sediments must have been land derieved.

Garnet and zircon are found associated with igneous and metamorphic rocks.

Weathering of these rocks release the minerals into sediments and are hereby transported into ocean basins. They can lithify in the sediments as they get carried along with them.

Terrigenous sediments originates from the land. They are made of rock materials and volcanic deposits. Some of them like volcanic dusts can travel into deeper parts of the oceans as they are lighter and can be carried very far into the ocean.
