Land, Soil, Water, Natural Vegetation And Wildlife Resources Flashcards
Which are the two main climate factors responsible for soil formation?
Temperature and rainfall are the two main climate factors responsible for soil formation. Rainfall contributes in breaking the rocks by applying pressure. Temperature fluctuations between hot and cold also form cracks in the rocks.
Write any two reasons for land degradation today.
Reasons for land degradation are:
The ever-growing demand of the growing population
Destruction of forest cover.
Why is land considered an important resource?
Land is an important resource because it provides space for agriculture, living, forestry, industries, construction, etc.
Name any two steps taken by the government to conserve animals and plants.
Steps taken by the government include the establishment of natural parks and wildlife sanctuaries in different parts of India. Their purpose is conservation of vegetation and wildlife, respectively.
Suggest 3 ways to conserve water.
Rainwater harvesting: Collecting water while it rains for future use.
Properly built irrigation channels to reduce water loss.
Drip or trickle irrigation in dry regions to conserve water.
How is land being degraded? Suggest methods to conserve land resources.
The ever-growing population has increased demand for living spaces, leading to deforestation and land degradation. Methods to conserve land resources include promoting afforestation, land reclamation, regulated use of chemical pesticides and fertilizers, and avoiding overgrazing.
What is weathering?
Weathering refers to the breaking up and decay of exposed rock caused by temperature fluctuations, frost actions, plants, animals, and human activities. It is a major process in soil formation and takes millions of years.
How is water an important resource?
Water is an indispensable source of life. It is essential for drinking, cleaning, cooking, irrigation, generating electricity, plant growth, and various industrial purposes.
Write a short note on wildlife.
Wildlife includes animals, birds, aquatic creatures, and insects. They provide important products such as milk, meat, hides, and wool. All forms of wildlife are integral to our ecosystem.
What are the major types of vegetation in the world? Describe vegetation in different rainfall conditions.
Major types of vegetation include forests, grasslands, scrubs, and tundra. In areas of heavy rain, dense forests with large trees thrive. In moderate rainfall areas, grasslands are common. In dry regions, thorny shrubs with deep roots and moisture-retentive leaves are found. Tundra vegetation consists of mosses and lichens.
What are landslides?
Land sliding down of slopes of mountains or hills, which can include stones, mud, and debris. They are more destructive in steep mountainous regions.
What is ecology?
Ecology is the scientific study of how living things interact with each other and their environment. It looks at how organisms are distributed, their abundance, their interactions, and how energy and matter flow through these systems.
What is an ecosystem?
An ecosystem is a community where biotic components (living organisms) interact with abiotic components (non-living elements like air, water, and soil). Ecosystems are often identified by their geographical regions.
