Answer:

There are three main processes that causes glacial erosion

a) Plucking

b) Abrasion

c) freeze and thaw

Explanation:

There are three main processes that causes glacial erosion

a) Plucking - In this the rocks at the base of glacier gets frozen and thus they stick to the ground. Now when the glacier starts moving, it plucks the rock from the ground. This process of eroding the frozen rocks at the base by the glaciers is called plucking.

b) Abrasion – Abrasion occurs when the plucked rocked by the glacier rub against the ground/bedrock  or side of the glaciers. This rubbing causes scouring and erosion of the bedrock.

c) Freeze and thaw – the water in the glacier melts during the day time and enters into the cracked rocks. During night time, the temperature drops and the water in the crack freezes and expands. This causes further widening of the cracks. This continues until the crack enlarges to an extent where it breaks the rock into smaller pieces.

I think the answer would be B but none of them are great. Continental drift is the gradual movement of our land masses. Knowing this we can eliminate option D because it identifies buildings as a cause. A and C both discuss climate change which is not a product of continents moving. The elimination leaves option B however because these changes would occur gradually, it is unlikely that species would become invasive.

10 things we need clean water for? ​
laila [671]

Answer:

Take shorter showers.  A four-minute shower uses approximately 20 to 40 gallons of water.

2. Turn off the tap.  When washing your hands, turn off the water while lathering up. Turning off the water while you brush your teeth helps to save over 150 gallons of water a month. Turn off the shower while you wash your hair and you’ll save another 150 gallons a month!

3. Fill ‘er up. Always run a full load of laundry, but if you can’t, make sure you adjust the settings to the proper load size. If you’re in the market for a new washing machine, look into a front-loading model– most are energy and water-efficient, using just over 20 gallons a load. Most top-loading machines, unless they are energy-efficient, use 40 gallons per load.

4. Fix it but don’t forget it.  Leaks can add up to 5 gallons a day! Check for leaks on all your hoses, faucets and connectors– fix ‘em but make sure to keep checking for leaks throughout your house.

5. There’s no such thing as “waste water”.  When you give your pet fresh water, don’t throw the water down the drain, water your plants with it instead. While you’re waiting for your water to heat up in the shower or washing your fruit and veggies, collect the water and use it again elsewhere!

6. Re-route rainwater.  A rain barrel watering system is awesome, but you can also install gutters and downspouts, directing the rainwater to your trees and shrubs. This saves water and reduces runoff.

7. Use a broom to sweep your driveway and sidewalks.  Hosing down your driveway and sidewalks is wasteful and contributes to poor ocean water quality. Use a broom and dustpan instead.

8. Follow best lawn practices.  Drought-resistant landscaping is best but if you do have a lawn, let it go dormant in winter. You only have to water every three to four weeks, less if it rains (or snows). When mowing, raise your lawn mower to 1.5 to 2.0 inches. Tall grass shades roots and holds in more moisture than short grass.

9. Water wisely.  Water plants and grass at night or in the early morning to minimize evaporation. Water deeply and less frequently to encourage deep root growth and drought tolerance. Use a kitchen timer or your smart phone timer so you don’t overwater.

10. Plant an Ocean Friendly Garden.  In many homes, more than half of the water goes to maintain thirsty plants and grass. Plants adapted to your region’s climate and soil require a lot less water and maintenance, and could save you up to half of your household water use!
