Calcium Carbonate or Lime Stone

How is fresh water collected in the rain forest?
uranmaximum [27]

Answer:

if you mean how you can gain water in the rainforest?

Kindly, look at below ^_^

Explanation:

The role of rainforests in the water cycle is to add water to the atmosphere through the process of transpiration (in which plants release water from their leaves during photosynthesis). This moisture contributes to the formation of rain clouds, which release the water back onto the rainforest.

Water Basics

 

The first thing you should do if you're stranded in the wild is find a source of drinkable water. The most obvious sources are streams, rivers and lakes. Animals always know where the water is, so be on the lookout for wildlife or animal tracks. Lush green vegetation is also a sign that water is nearby. Swarming insects may be a hassle, but they also signal that a water source isn't far away. Bird flight paths in the morning or evening can point you in the right direction. Stay on the move until you find a water source. When you pause to rest, use your ears -- rivers can be heard in the quiet woods from great distances. Remember that water always flows downhill, so low-lying areas and valleys are a good bet.

If you find a muddy area, there may be groundwater available. Dig a hole about a foot deep and one foot in diameter and wait. You may be surprised to find that the hole is soon filled with water. This groundwater will be muddy, but straining it through some cloth will clean it up, and it will get you by in the short term. It's crucial to remember that any time you drink found water without purifying it, you're taking a risk.

HOPE THAT ASSESS YOU ...
