Ans: Two characteristics of the High Mountainous region are:
(i) Steep Slopes: Steep slopes are legally defined as hillsides having a 15 foot, or greater, vertical rise over 100 feet of horizontal run, or 15% slope .
(ii) Low Temperatures: Due to high altitudes, the region experiences cooler temperatures, with snow-covered peaks and harsh weather conditions, especially at higher elevations.
11. What is a hydrological cycle?
Ans: The hydrological cycle, also known as the water cycle. is the continuous movement of water within the Earth and atmosphere. It involves processes like evaporation, condensation, precipitation, and runoff. Water circulates between oceans, atmosphere, and land, sustaining ecosystems and regulating the planet’s climate.
12. Mention two consequences of deforestation.
Ans: Two consequences of deforestation are:

Ans: Water pollution is the release of substances into bodies of water that makes water unsafe for human use and disrupts aquatic ecosystems. Water pollution can be caused by a plethora of different contaminants, including toxic waste, petroleum, and disease-causing microorganisms.
Two causes of water pollution are:
(i) Industrial Discharge: Factories and industries release harmful chemicals, heavy metals, and untreated wastewater into rivers, lakes, and oceans, contaminating the water.
(ii) Agricultural Runoff: The use of pesticides, fertilizers, and herbicides in farming can wash into nearby water bodies, leading to pollution and harming aquatic life.
23. Write a note on global warming.
Ans: Global warming refers to the long-term increase in Earth’s average surface temperature due to human activities, particularly the emission of greenhouse gases (GHGs) such as carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O). These gases trap heat in the Earth’s atmosphere, creating the “greenhouse effect” and causing the planet to warm up. The primary sources of these emissions include burning fossil fuels (coal, oil, natural gas) for energy, deforestation, agriculture, and industrial processes.
Global warming is the long-term heating of Earth’s surface observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere. This term is not interchangeable with the term “climate change.”
24. Write briefly about the geographical condition of the Tundra region.
Ans: The tundra climate region geographically located between 60° and 75° of latitude, mostly along the Arctic coast of North America and Eurasia and on the coastal margins of Greenland. In such areas, winters are long and cold especially in the region north of the Arctic Circle.The Tundra region is characterized by extreme cold temperatures, short summers, and long, harsh winters. It is found in high latitudes, particularly in the Arctic and parts of Antarctica, as well as in alpine areas at high altitudes. The landscape is mostly flat, with frozen soil known as permafrost, which remains permanently frozen. Vegetation is sparse, consisting mainly of mosses, lichens, grasses, and small shrubs due to the cold climate and short growing seasons.
25. Briefly describe the location and spatial extent of the continent of Africa.
Ans: Africa is the second-largest continent in the world, both in terms of area and population. It is located primarily in the Eastern Hemisphere, with the Equator passing through its central region, dividing it into northern and southern halves.

These regions experience intense daytime heat and sharp temperature drops at night. Vegetation is sparse, consisting mainly of drought-resistant plants like cacti, shrubs, and thorny bushes. The soil is sandy or rocky, with low organic content. Water sources are scarce, typically found in oases. Hot deserts, such as the Sahara and the Thar, also face frequent dust storms. Wildlife includes species adapted to arid conditions, such as camels, snakes, and scorpions, showcasing unique survival adaptations to harsh environments. A hot desert is a hot and dry area with very little precipitation and low biodiversity. Most, but not all, hot deserts are found near the equator. Hot deserts can form as a result of prevailing wind patterns or from the rain shadow effect. Soils in hot deserts are dry and lacking in nutrients.
31. Briefly describe the Characteristics of agriculture in Japan.
Ans: The Characteristics of agriculture in Japan are:
(i) Small and Fragmented Farmlands: Due to Japan’s hilly terrain and dense population, farmlands are small and fragmented.
(ii) Intensive and Scientific Cultivation: To maximize yields, intensive farming methods are employed, using fertilizers and advanced techniques.
(iii) Diverse Agricultural Practices: Practices like terrace cultivation, mixed farming, inter-culture farming, and shifting cultivation are common.
(iv) Dominance of Rice Cultivation: Rice is the primary crop, occupying about two-thirds of the cultivated land.

32. Briefly discuss the Distribution of rainfall in India.
Ans: India exhibits a diverse distribution of rainfall due to its varied topography and monsoonal influences. High rainfall areas, receiving more than 300 cm annually, include the foothills of the Himalayas, the southern parts of the Meghalaya Plateau, and the western slopes of the Western Ghats. Notably, Mawsynram and Cherrapunji in Meghalaya exceed 400 cm of annual rainfall, making them some of the wettest places on Earth. In contrast, low rainfall regions such as the Thar Desert and surrounding areas in Rajasthan receive less than 50 cm annually, with some locations experiencing rainfall below 20 cm. Similarly, the northern and western Deccan Plateau and parts of Gujarat receive between 50 cm and 100 cm. Moderate rainfall areas, including the northern plains and the Brahmaputra Plain, experience an average annual rainfall of 100 cm to 200 cm. This variation significantly impacts agriculture, vegetation, and water availability across the country.
