Topic 2: Environmental influences on Agricultural practices

 Water cycle




What is water cycle?

.Refers to the ongoing movement of water in the Earth's atmosphere through a number of different processes, including evaporation, condensation, precipitation, infiltration and runoff.

Describe the water cycle 

 The water cycle operates as follows:

 1. Evaporation: 

Water from rivers, lakes, oceans, and other bodies of water is heated by the sun and turns into water vapor, which rises into the atmosphere.

 2. Condensation: 

As water vapor rises and cools, it condenses into tiny droplets, forming clouds in the atmosphere. 

3. Precipitation: 

These droplets combine and grow heavy enough to fall back to Earth as precipitation, which takes the form of rain, snow, sleet, or hail.  

4. Infiltration:

 Water seeps into the earth and becomes groundwater, which travels through subsurface layers of rock and soil. 

5. Runoff: 

Water travels over the ground and returns to seas and lakes, ready to start the cycle again.

Note: Through the distribution of water throughout the planet, this cycle is essential to preserving Earth's climate and sustaining life.


Significance of ground water resources 

Groundwater resources are extremely important for a number of reasons:

1. Used for drinking purpose 

They supply a large amount of the fresh water used globally for drinking and sanitation, particularly in arid and semi-arid regions where surface water is scarce.

2. Agricultural Use

Groundwater is essential for irrigation in agriculture, helping to ensure food security and support livelihoods in many regions. 

3. Industrial Uses

Groundwater is essential for processes and cooling in many industries, making it essential for economic activities. 

4. Ecosystem Support

Groundwater contributes to the base flow of rivers and wetlands, supporting aquatic ecosystems and maintaining biodiversity.

5. Drought Resilience

It acts as a buffer during times of drought, providing a more dependable source of water when surface water is scarce.

Topic 6: Principles of plant growth

  Explain the concept turgor and plasmolysis Define the term Tugor Turgor pressure is the force exerted by fluid inside a plant cell that pushes the cell membrane against the cell wall, contributing to the rigidity of living plant tissue.  .This pressure is crucial for maintaining the structural integrity of plants, allowing them to stand upright and maintain their shape.  .A loss of turgor pressure, typically due to water loss, leads to wilting in flowers and leaves as the cells lose their firmness.  Define the term Plasmolysis Plasmolysis is defined as the process of contraction or shrinkage of the protozam of a plant cell and is caused due to the loss of water in the cell. Plasmolysis is an example of the results of osmosis and rarely occurs in nature. Differences between Turgor and Plasmolysis  .Plant Cells: Plants are made up of cells that cooperate to support growth and structural integrity. The proper maintenance of energy and operation of these cells is greatly influenced by wa

Topic 4: Soil Types

Image
  Describe the main characteristics of Clay soil, Sand soil, and Loam soil Clay soils are heavy, high in nutrients, wet and cold in winter and baked dry in summer Characteristics   . Poor drainage  . Difficult to cultivate because the soil is sticky when wet. . High organic content . Poor aerated due to particles closely packed together  . Has blocky structure  Sandy soils are light, dry, warm, low in nutrients and often acidic Characteristics   . Low water holding capacity  . Low fertility . Fast drainage because of large particles  . Easy to cultivate  . It is structureless   Loams are mixtures of clay, sand and silt that avoid the the extreme of each type.                                    Loam soil Characteristics   . Right amount of air . Rich in organic matter . Easy to cultivate  . It has a crumb structure Click on the link below for more videos! Thank you!   https://youtu.be/QtwMIIRX8TM?si=g14H82VkPad9FtEn
