BREAKING THE CYCLE

  • He water cycle can change glacial retreat is the process In Which glaciers melt faster than their ice can be replaced by precipitation. Glacial retreat limits the amount of fresh water available on Earth. We are experiencing the fastest rate of glacial retreat in recorded history.

STATES OF WATER

  • Thought the water cycle water continually circulates three states:solids,liquid and vapour
  • Ice is solid water. Most of Earth's freshwater is ice, locked in massive glaciers, ice sheets, and ice caps.
  • As ice melts, it turns to liquid. The ocean, lakes, rivers, and underground aquifers all hold liquid water.
  • Water vapor is an invisible gas. Water vapor is not evenly distributed across the atmosphere. Above the ocean, water vapor is much more abundant, making up as much as 4% of the air. Above isolated deserts, it can be less than 1%.
