Deforestation increases the amount of runoff because plants are not present to absorb the water.
Increased surface runoff has increased water pollutants
Answer:
acid rain has a pH value of 4.0.
Explanation:
so less than 7
o
testing and adopting new technologies for agriculture
developing new crops to grow while still growing traditional varieties
o meeting current needs while preserving resources for the future
O
decreasing short-term costs and increasing long-term income
Answer:
-meeting current needs while preserving resources for the future
Explanation:
Sustainability involves meeting developmental goals while maintaining ecological balance and preserving natural resources for the future. Similarly, sustainable farming describes the way agricultural practices can be improved via the use of technologies for small and industrial-sized farms, in both the local and global economies. Social responsibility, while providing adequate food, goods and services, is just one benefit to sustainable agriculture. This approach is also based on the improvement of environmental responsibility and economic efficiency for the sake of future generations.
- most minerals occur in more than one color
- color is more accurate than streak in identifying minerals
- steak is tested by scraping a mineral across a streak plate
- the color of the streak is the same as the color of the mineral
Answer:
A mineral is an inorganic substance that is extracted from the ore after the mining process. The mineral can be identified on the basis of physical properties like color, luster, appearance, texture and by the chemical composition.
The streak is the method of mineral identification in which the mineral is scrapped off across a streak plate to determine the exact color of the mineral by the color of the powder as two or more minerals may look alike on the basis of color. This method will allow to determine the exact color of the mineral.
On the basis of the above description, these are correct statements:
- streak is the color of a minerals powder.
- most minerals occur in more than one color.
- steak is tested by scraping a mineral across a streak plate.
