Choose ALL of the phases of matter listed<br> that are able to flow:<br> gas<br> liquid<br> solid
IrinaK [193]

Answer:

- gas

- liquid

Explanation:

     Part of the definition of gases and liquids is the ability to flow, so this answers your question.

     Why does this not apply to solids? The cells in a solid are closer together with less room for movement, so they do not "flow" like gasses or liquids. You can think of the device you are asking this question on versus the water in the ocean.

<u>Note</u>: Gas can still flow, but it does not flow the same as water. It depends on what you are being taught for if gas flows or not.

-> Liquid flows from high to low only, while gas can flow in all directions

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

     ★ Also please leave the rating you think I deserve (It helps other users as well as myself)

A method used by horticulturalists when they rotate the use of fields—planting crops on a particular piece of land for a period
svetoff [14.1K]

Answer:

The correct answer will be- Crop rotation

Explanation:

When the growth of a type of crop which uses soil nutrients in abundance and then growing another crop in the same filed led to the decrease in the production of the next crop.

Thus farmers adapted to avoid such farming practices and developed a new practice which allowed the land to become fertile again so that the growth of next crop will not be affected.

The practice involved the planting of a crop on a piece of land then leaving the soil ploughed and unsown for a longer period of time and growing corp on another piece of land allowing the time to restore the nutrient content. This practice is known as "crop rotation".

Thus, crop rotation is the correct answer.
