Why are lichens called soil formers

Biology
1 answer:
Ipatiy [6.2K]3 years ago
6 0

Answer:

Lichens are not parasitic when they grow on trees, they just use the tree bark as a home. They enrich the soil by trapping water, dust and silt. When lichens die they contribute organic matter to the soil, improving the soil so that other plants can grow there.

Factors that affect rate of erosion
Tcecarenko [31]

Answer:

farm management, rainfall, climate, soil type, soil cover, landscape, type of wave, crops, rock strength and position of coast.

Explanation:

Erosion can be defined as a geological process which typically involves the wearing out of earthen (soil) materials and the transportation of these materials by natural forces like water, wind, etc. Soil erosion is greatest when the soil is steep.

The steepness of a body such as river or stream refers to the downward slope or gradient of the body of water.

Generally, the steepness of a body affects the rate at which other materials would flow or move around. Thus, the steeper a river or stream, the greater would be its rate of erosion.

Other factors that affect the rate of erosion in an area include the following; farm management, rainfall, climate, soil type, soil cover, landscape, type of wave, crops, rock strength and position of coast.

using the equation cs2+3o2=co2+2so2 what is the percent yield of so2 if the burning of 12.5g of cs2 produces 15.12 g of SO2
vesna_86 [32]
<h3><u>Answer;</u></h3>

  = 71.96%

<h3><u>Explanation</u>;</h3>

1 mole of CS2 = 76.133 g

1 mole of SO2 = 64.06 g

1 mole of CS2 reacts with 3 moles of Oxygen to produce 2 moles of SO2

Moles of CS2 in 12.5 g = 12.5/76.133

                                      =  0.164 moles

Mass of SO2 = 0.164 mol × 2 × 64.06

                      = 21.01168 g

Therefore;

Percentage yield of SO2

  = 15.12/21.01168 × 100%

<u>   = 71.96%</u>
