Class 7 Social Science - ICSE-GEOGRAPHY
Natural Vegetation
The chapter Natural Vegetation in Class 7 ICSE Geography explores the plant life that grows naturally without human intervention. Students learn about the major types of forests and grasslands found across the world, ranging from the dense Tropical Evergreen Forests near the equator to the freezing Tundra regions. The chapter highlights how temperature, rainfall, and soil determine the type of vegetation in a region. This is crucial for board exams as it builds the geographical foundation for understanding global ecosystems, climate patterns, and wildlife distribution, frequently featuring in map-pointing and descriptive questions.

Natural Vegetation
Plant life that grows naturally in an area without human interference, shaped entirely by climate, soil, and relief.
Tropical Evergreen Forests
Dense forests found near the equator experiencing heavy rainfall year-round, where trees never shed all their leaves at the same time.
Tropical Deciduous Forests
Monsoon forests where trees shed their leaves during the dry season to conserve water, commonly found in India.
Temperate Grasslands
Vast areas of grass with very few trees, located in the mid-latitude zones with moderate rainfall, known as prairies or steppes.
Tundra Vegetation
Extremely cold polar regions where only low-growing mosses, lichens, and dwarf shrubs manage to survive.

Board Exam Info
In ICSE Class 7 Geography, this chapter typically carries 8 to 12 marks. Common question types include map-pointing (identifying forest types on a world map), differentiating between evergreen and deciduous forests, and short-answer questions explaining the adaptations of plants in deserts or tundra regions.
Frequently Asked Questions
Why are Tropical Evergreen Forests called evergreen?
They are called evergreen because different types of trees shed their leaves at different times of the year, so the forest always appears green.
What is the main difference between forests and grasslands?
Forests grow in areas with high to moderate rainfall and have a dense canopy of trees, whereas grasslands grow in regions with moderate to low rainfall where grass is the dominant plant life.
How do plants survive in desert regions?
Desert plants have special adaptations like long roots to search for water, waxy leaves or thorns to reduce water loss, and succulent stems to store water.
