The statement 'Pacific Ring of Fire consists only of extinct volcanoes' is FALSE.
The Pacific Ring of Fire is a major area in the basin of the Pacific Ocean known for its high volcanic and seismic activity. It is a horseshoe-shaped ring that spans approximately 40,000 kilometers (25,000 miles) and is associated with a series of oceanic trenches, volcanic arcs, volcanic belts, and plate movements.
The Ring of Fire is home to approximately 75% of the world's active volcanoes, making it a highly active volcanic region. However, it is important to note that the Ring of Fire consists not only of active volcanoes but also includes dormant and extinct volcanoes.
Extinct volcanoes are those that are no longer expected to erupt in the future. They have become inactive and have not shown any signs of volcanic activity for a significant period of time. While the Ring of Fire is known for its active volcanoes, there are also dormant and extinct volcanoes within the region.

Answer:
Explanation:
1. Agriculture: Extensive agricultural practices, such as improper land management, overgrazing, and the use of heavy machinery, can lead to soil erosion. When soil is exposed and not adequately protected by vegetation, it becomes vulnerable to wind and water erosion.
2. Construction and Urbanization: The construction of roads, buildings, and other infrastructure often involves the removal of vegetation and the disturbance of natural landscapes. This can increase the likelihood of erosion, especially during rainfall events, as the natural drainage patterns and soil stability are disrupted.
3. Deforestation: The removal of forests for timber, agriculture, or urban development exposes the soil to erosion. Forests play a crucial role in preventing erosion by holding the soil together with their roots and providing a protective layer of vegetation.
4. Mining Activities: Mining operations can result in significant land disturbance, leading to erosion. Excavation and removal of soil or rock can destabilize slopes and expose bare surfaces prone to erosion.
5. Improper Land Management Practices: Improper land management practices, such as improper irrigation, inadequate soil conservation techniques, and over-extraction of resources, can exacerbate erosion. These practices can deplete the soil's fertility and disrupt its natural balance, making it more susceptible to erosion.

Answer:
Option (1)
Explanation:
Out of all the water body (total composition) present on earth, about 97% is the ocean saline water and the remaining 3% comprises the freshwater that includes the water of the rivers, lakes, streams and ponds.
Again, from this total amount of freshwater (3%), the glaciers and ice caps cover nearly 68% of it, groundwater covers about 30% and some other surface (fresh) water comprises the remaining 2%.
So, in simple words, it can be concluded that about 2% (68/100*3) of the freshwater is occupied by the glaciers.
Thus, from the given options, the most approximate value is 2.15% which is option (1).
