I believe its lack of worthy projects, but ill tell you if im wrong.
Some of the factors would be introduction of non native species, pollution, overgrazing, chemical agents and habitat loss
Answer:
<u>In glaciers, North and South poles and some lakes.</u>
Explanation:
- As more than 70% of freshwater can be found in continental glaciers around the world. The rest is in icecaps and 0.5 % store in lakes and rivers, and swamps.
- Rest if possible may be found in the groundwater aquifers, hidden in remote and cut off lace of the world.
- Antarctica and arctic alone consist of a huge share of freshwater in the world which is stored in ice forms. While 97% of oceanic water is saline not fit for drinking.
- Various techniques are available for desalination of water but most of it not suitable for long term use. As it may have bacteria and harmful effects on the body. Due to climate change release of methane gas and other harmful greenhouse gases are quickly melting and depleting the freshwater r
North to south (opposites attract ;) )
"Erratics" are large rocks that are not the same as the rock types found in the area and are deposited by the glaciers as they move or melt.
<h3>What are erratics?</h3>
Stones and rocks that were carried by a glacier and then abandoned after the glacier melted are known as glacial erratics.
Some characteristics of erratics are-
- The bedrock where the glacial erratic is deposited has a distinct lithology from the sort of rock that makes up the glacier erratic.
- A sandstone boulder moved by a glacier and placed on top of limestone bedrock would be an example of an erratic.
- Scientists can identify and locate the source outcrop of some erratics because they are made of a particular type of distinguishable rock.
- In order to recreate historical glacier flow directions, the timing of glacier retreat, and even the type of glacier flow, it is helpful to analyze glacial erratics.
- Large boulders, tiny stones, and pebbles can all be erratic. Every erratic is made of a unique sort of rock.
