D) Contour plowing is used to reduce erosion and sediment pollution.
Explanation:
Contour plowing in farming helps to prevent pollution by reducing surface erosion of topsoil and preventing sediment pollution.
Contour plowing is a farming technique in which crops are planted along the slopes of hills or contoured areas.
- The rate at which rain water and precipitation moves along slope terrain is very fast.
- This causes the washing off of the the topsoil on hills to eroded very fast.
- Contour plowing breaks the slope and farming is done along movement on the contour.
- This prevents topsoil erosion.
- It also prevents sediment pollution in nearby streams and water bodies that are located around the valley at the base of the hill.

Answer:
B. Sea levels will rise , causing floods
Answer:
Chemical families on the periodic table are the following:
1) Alkali metals.
2) Alkaline earth metals.
3) Transition metals.
4) Halogens.
5) Noble gases
Explanation:
Alkali metals are those elements having one electron in the outermost shell. Alkaline earth metals are found in the earth such as calcium. Halogens means salt forming, it produces salts when combine with alkali. Noble gases are those which are non-reactive in nature.
This should be the answer for the Krebs cycle
A solar flare is a magnetic storm on the Sun which appears to be a very bright spot and a gaseous surface eruption. Solar flares release huge amounts of high-energy particles and gases and are tremendously hot (from 3.6 million to 24 million °F). They are ejected thousands of miles from the surface of the Sun.<span>A solar prominence (also known as a filament) is an arc of gas that erupts from the surface of the Sun. Prominences can loop hundreds of thousands of miles into space. Prominences are held above the Sun's surface by strong magnetic fields and can last for many months. At some time in their existence, most prominences will erupt, spewing enormous amounts of solar material into space.</span>
