The heat budget is the equilibrium between incoming solar radiation and outgoing terrestrial radiation, crucial for maintaining Earth’s temperature and climate stability. It involves absorption, reflection, and the greenhouse effect. Imbalances lead to global warming and severe climate changes, influenced by factors like latitude and greenhouse gas concentrations.
Tag: Notes
Heat transfer is the movement of thermal energy from hot to cool objects, occurring through conduction (solids), convection (liquids and gases), and radiation (without a medium). Each mode has practical applications in daily life, such as cooking, weather patterns, and energy generation. Understanding these principles is crucial across various fields.
Atmosphere
The atmosphere, a gas layer surrounding Earth, is essential for sustaining life by providing oxygen and regulating temperature. It consists mainly of nitrogen and oxygen, with various layers serving distinct functions. Key issues include the greenhouse effect and ozone depletion, which pose environmental challenges requiring urgent action for sustainability.
What is Soil? Composition of Soil ✅ Mineral Particles – Sand, silt, and clay.✅ Organic Matter – Decomposed plants and animals (humus).✅ Water – Moisture essential for plants.✅ Air – Provides oxygen for roots and soil organisms.✅ Microorganisms – Bacteria, fungi, and insects that help decompose organic material. Factors of Soil Formation Types of Soil […]
Underground Water Landforms
Underground water, stored beneath the Earth’s surface, shapes landforms through erosion and deposition, particularly in areas with limestone, creating features like caves, sinkholes, and stalactites. These landforms are important for freshwater resources, tourism, scientific research, and cultural significance, exemplified by famous sites like the Ajanta Caves and Yellowstone National Park.

Wind is a significant force in erosion and deposition, especially in deserts and coastal areas. Aeolian processes include erosion, transportation, and deposition, resulting in various landforms like deflation hollows, mushroom rocks, sand dunes, and loess deposits. These formations enhance agricultural productivity and attract tourism while acting as natural barriers.

Landforms Made by Rivers
Rivers significantly shape the Earth’s surface by creating various fluvial landforms through erosion, transportation, and deposition across three stages: upper (youthful), middle (mature), and lower (old). These landforms, including V-shaped valleys, meanders, and deltas, hold ecological, agricultural, and economic importance, enhancing fertility and supporting tourism and navigation.
Weathering
What is Weathering? Types of Weathering 1. Physical Weathering (Mechanical Weathering) Examples of Physical Weathering ✅ Frost Action (Freeze-Thaw Weathering) – Water enters rock cracks, freezes, expands, and breaks the rock.✅ Thermal Expansion – Repeated heating and cooling cause rocks to crack.✅ Exfoliation – Outer rock layers peel off due to temperature changes.✅ Abrasion – […]
