How many millimetres (equivalent depth) of water are

Biology

Alla [95]2 years ago
6 0

The equivalent depth of water in the soil is 270 mm and the volumetric water content of soil is 5625 cubic meter/ 1.5 hectare of soil.

<h3>How can equivalent depth of water in a soil be calculate?</h3>

The equivalent depth of water in a soil is calculated using the formula below:

  • equivalent depth of water = water content × depth of soil

The depth of soil profile 1 = 1 m = 1000 mm

The depth of soil profile 2 = 600 mm

Equivalent depth of water in the soil = 15% × 1000 mm + 20% × 600 mm

Equivalent depth of water in the soil = 150 mm + 120 mm

Equivalent depth of water in the soil = 270 mm of water

The volumetric water content of the soil is calculated using the formula below:

  • Volumetric water content = water content × bulk density of soil/density of water × height of soil

Height of soil profile 1 = 1 m

Height of soil profile 2 = 0.6 m

Volumetric water content of soil profile 1 = 15% × 1300/1000 × 1 m = 0.195 cubic meter/square metre of soil

Volumetric water content of soil profile 1 = 20% × 1500/1000 × 0.6 m = 0.18 cubic meter/square metre of soil

Total Volumetric water content of soil = 0.18 + 0.195 = 0.375 cubic meter/square metre of soil

Converting to cubic meter/hectare of soil:

0.375 cubic meter/square metre of soil

1.5 hectares = 15000 square metre

Volumetric water content of soil = 0.375 × 15000 cubic meter/ 1.5 hectare of soil

Volumetric water content of soil = 5625 cubic meter/ 1.5 hectare of soil

Therefore, the equivalent depth of water in the soil is 270 mm of water and the volumetric water content of soil is 5625 cubic meter/ 1.5 hectare of soil.

Explain how soaring and gliding birds use their air currents in their flight
ira [324]

Soaring and gliding birds like eagle, vulture, albatross, sea gulls etc are efficiently adapted to utilize the air currents in their flight.

Explanation:

The soaring flight and gliding movements are special adaptation developed by birds to meet the challenge of increasing turbulent air current.

Birds have the extraordinary skill of flying smoothly and effortlessly even at very high altitudes  

Birds soar by using thermal and dynamic soaring techniques.

Gliding movements help the birds to deflect the wind downward which helps to lift their bodies in the air. They do not flap their wings during gliding but just dive straight into the air which helps to increase their speed.

The adaptation of the bird’s structure with very light but strong bones on their wings helps to soar and glide in the air.

Using the graphs below, determine which water drop rate leads to the highest seed growth.
expeople1 [14]

Answer:

C. 50 drops/hr

Explanation:

As we can see in the description of the graph above, 50 drops/hr was the rate of water fall that was most successful in plant growth. This is because with this rate, the seeds germinated more quickly, the seedlings showed a strong and fast vegetative growth, besides that at the end of 5 days, it was observed that germination of almost 100% of the seeds occurred. These facts cannot be observed with the other waterfall rates, so the correct answer is 50 drops/hr.

Pls answer in the next couple of minutes
Simora [160]

Answer:

Groundwater

Although this may seem surprising, water beneath the ground is commonplace. Usually groundwater travels slowly and silently beneath the surface, but in some locations it bubbles to the surface at springs. The products of erosion and deposition by groundwater were described in the Erosion and Deposition chapter.

Groundwater is the largest reservoir of liquid fresh water on Earth and is found in aquifers, porous rock and sediment with water in between. Water is attracted to the soil particles and capillary action, which describes how water moves through a porous media, moves water from wet soil to dry areas.

Aquifers are found at different depths. Some are just below the surface and some are found much deeper below the land surface. A region may have more than one aquifer beneath it and even most deserts are above aquifers. The source region for an aquifer beneath a desert is likely to be far from where the aquifer is located; for example, it may be in a mountain area.

The amount of water that is available to enter groundwater in a region is influenced by the local climate, the slope of the land, the type of rock found at the surface, the vegetation cover, land use in the area, and water retention, which is the amount of water that remains in the ground. More water goes into the ground where there is a lot of rain, flat land, porous rock, exposed soil, and where water is not already filling the soil and rock.

The residence time of water in a groundwater aquifer can be from minutes to thousands of years. Groundwater is often called “fossil water” because it has remained in the ground for so long, often since the end of the ice ages.
