Certainly! Here are some essential resources suitable for agriculture: 1. **Land**: Suitable land with fertile soil and proper drainage. 2. **Water**: Adequate and reliable water supply for irrigation, either through natural sources like rivers and lakes or artificial systems like wells and ...
Continental drift theory, given by Alfred Wegner in 1912, suggests that all the continents are formed from a single continental mass 'namely PANGAEA' surrounded by mega ocean 'namely PANTHALASSA'. He argued that around 200 million years ago PANGAEA broke into various continents. Evidences in supportRead more
- Continental drift theory, given by Alfred Wegner in 1912, suggests that all the continents are formed from a single continental mass ‘namely PANGAEA’ surrounded by mega ocean ‘namely PANTHALASSA’.
- He argued that around 200 million years ago PANGAEA broke into various continents.
Evidences in support of the continental drift theory:-
The Jig-Saw-Fit (matching of continents):-
The shorelines of South America and Africa facing each other have remarkable and unmistakable match.
The rocks of same age across the oceans:-
radiometric dating methods have correlated the rock formation in different continents.
eg- marine deposits along the coastline of south america and africa are of the Jurassic age.
Tillite:
The glacial tillite found in Gondwana system of sediments has its resemblance to six different landmasses of the Southern Hemisphere.
Placer Deposits:
The placer deposits of gold in the Ghana coast do not have source rock in the region.
Distribution of Fossils:
identical species of plants and animals adapted to living on land or in freshwater are found on either side of the marine barriers.
END:-
The Continental Drift Theory had some limitations they are mentioned below:
- Wegener was unable to clarify why the drift started.
- the forces described by wegner that propelled the movement of continents were, too weak to move continents.

Organic farming is very important in India. It is a way to grow food without the use of chemical fertilizers, synthetic pesticides, or genetically modified organisms (GMOs). Instead, organic farmers use methods such as biofertilizers and animal and plant waste to control pests.
Organic farming supports healthy ecosystems, biodiversity and biological cycles. It also helps save water and reduce pollution. The demand for organic produce is increasing in India and other countries. This means farmers can make more money by growing organically.
Organic produce is free of chemicals and pesticides that are harmful to our health. Eating organic food can help reduce the risk of disease and improve health. It’s a way to promote permaculture, support local farmers, and provide healthy food to consumers.
