To answer this question, let's analyze the consequences of cutting down all trees in a forest:
Erosion of Soil:
- Trees play a crucial role in preventing soil erosion. Their roots hold the soil in place, preventing it from being washed away by rain or wind.
- Without trees, the top layer of soil becomes exposed to the elements, leading to increased erosion.
- Erosion can result in the loss of fertile topsoil, making it difficult for plants to grow and reducing agricultural productivity.
Desertification:
- Trees contribute to the overall moisture levels in an area through the process of transpiration.
- When trees are absent, the moisture levels decrease, and the land becomes drier.
- With prolonged absence of trees, the land can gradually turn into a desert, a process known as desertification.
- Desertification leads to the loss of biodiversity, reduced water availability, and the inability to sustain plant and animal life.
Therefore, cutting down all trees in a forest leads to both erosion of soil and desertification. Therefore, the correct answer is option C: both (a) and (b).

Why cattles should be stopped from overgrazing to conserve forests:
- Overgrazing by cattles can have negative impacts on forests and their biodiversity. It is important to control their grazing activities to maintain a healthy balance.
- Overgrazing can lead to the depletion of grass and other vegetation in the forest area.
- When cattles eat too much grass, it affects the natural regeneration of plant species, leading to a decline in the forest's overall health.
- Overgrazing also damages the soil structure, making it more susceptible to erosion.
- Erosion can result in the loss of fertile topsoil, which further degrades the forest ecosystem.
- Uncontrolled grazing can also lead to the spread of invasive plant species, which can outcompete native vegetation and disrupt the natural balance of the forest.
- By stopping cattles from overgrazing, the forest ecosystem can recover and regenerate naturally, promoting biodiversity and preserving the overall health of the forest.
Conclusion:
Controlling overgrazing by cattles is essential for the conservation of forests and their biodiversity. By preventing overgrazing, we can ensure the long-term sustainability of forests and protect their ecological integrity.

Explanation:
The correct answer is C: storms. Deforestation refers to the clearing, destroying, or removal of forests or trees. It has various negative impacts on the environment and ecosystems. However, storms are not directly caused by deforestation. Here are detailed explanations of the other options:
A: Desertification:
- Deforestation can contribute to desertification, which is the process of fertile land turning into desert-like conditions.
- Trees play a crucial role in retaining moisture in the soil, and their removal can lead to soil erosion, reduced water retention, and the loss of fertile land.
B: Global warming:
- Deforestation significantly contributes to global warming and climate change.
- Trees absorb carbon dioxide from the atmosphere and act as carbon sinks, helping to regulate the planet's temperature.
- When forests are cleared, the stored carbon is released into the atmosphere, contributing to the greenhouse effect and global warming.
D: Reduction in groundwater:
- Deforestation can lead to a reduction in groundwater levels.
- Trees play a vital role in absorbing and retaining water through their roots, which helps maintain groundwater levels.
- Without trees, rainwater is not efficiently absorbed into the ground, leading to decreased groundwater availability.
In summary, while deforestation can cause desertification, global warming, and a reduction in groundwater, it does not directly cause storms. Storms are natural weather phenomena that occur due to atmospheric conditions and other factors.
