Heat exhaustion occurs when the body loses excessive amounts of water and salt through sweating. This depletion of fluids and electrolytes impairs the body's ability to regulate temperature and can lead to dizziness, weakness, and nausea if not treated.

The Luni is the only significant river that flows through the Thar Desert in Rajasthan. It originates in the Aravalli Range and flows through the arid regions of Rajasthan before finally draining into the Rann of Kutch. Other rivers listed (Narmada, Krishna, Beas) flow through different geographical regions.

Heat exhaustion is actually more common in people who are not acclimatized to heat, elderly people, and those with certain medical conditions. While blood pressure issues can be a factor, people with low blood pressure are not specifically identified as the most prone group. Other risk factors are more significant.

Nagarjunasagar Dam is built across the Krishna River in Telangana. It is one of the largest dams in India and was completed in 1967. The Krishna River flows through Maharashtra, Karnataka, Telangana, and Andhra Pradesh.

Contour lines on a map connect points of equal elevation above a reference point like sea level. These lines are drawn at fixed vertical intervals and help visualize the three-dimensional shape of terrain on a two-dimensional map. Hachures show steepness, spot heights give individual elevations, and isomers are unrelated to maps.

The listed symptoms are not accurate warning signs of heat exhaustion. The actual warning signs include heavy sweating, weakness, dizziness, nausea, headache, and pale skin. Lack of sweat and flushed face are more associated with heat stroke, which is more severe.

Stagflation is an economic condition characterized by stagnant economic growth, high unemployment, and rising prices (inflation). This combination creates a difficult policy situation because measures to reduce inflation can worsen unemployment, and vice versa. The term gained prominence in the 1970s during the oil crisis.

In heat exhaustion, the pulse rate typically becomes fast and weak as the body struggles to circulate blood effectively due to dehydration. Breathing becomes rapid and shallow as the body attempts to compensate. These are important signs for identifying the severity of heat-related illness.

Narmada flows westward into the Gulf of Khambhat, forming a well-developed estuary. Most major Indian rivers (like Krishna, Mahanadi, Kaveri) form deltas instead of estuaries because they carry heavy sediment loads that deposit at river mouths, creating extended landforms.

Charak, the renowned ancient Indian physician and author of the Charaka Samhita foundational text of Ayurveda, served in the court of Kanishka, the Kushan ruler. The Kushan period (1st-2nd century CE) was a golden age for medical scholarship in India.

Heat stroke is the most severe heat-related illness and can develop from untreated heat exhaustion. As the body's temperature regulation fails, the core temperature rises to dangerous levels (above 40°C), potentially leading to organ damage, confusion, and loss of consciousness.

The Great Stupa at Sanchi, commissioned by Emperor Ashoka in the 3rd century BCE and later enlarged, is located in Raisen district of Madhya Pradesh. It is one of the oldest stone structures in India and a UNESCO World Heritage Site.

Alcohol dehydrates the body and worsens heat stress by interfering with temperature regulation, while hot baths increase core temperature - the opposite of what's needed. Effective cooling measures include cool water, proper hydration with water or electrolyte solutions, resting in shade, and avoiding strenuous activity.

The four ashramas represent life stages in sequence: Brahmacharya (celibate studenthood, childhood/adolescence focused on learning), Grihastha (married householder, adulthood with family responsibilities), Vanaprastha (gradual withdrawal to forest life, senior years), and Sanyasa (complete renunciation, final stage of spiritual pursuit).

Refrigeration slows down microbial growth (bacteria and molds) by lowering temperature to around 4°C, but it doesn't kill germs or sterilize food. At low temperatures, most microbes become dormant or multiply very slowly, significantly extending food's shelf life without eliminating microorganisms.

Birds possess a unique respiratory system with air sacs that allow unidirectional airflow through lungs, enabling highly efficient oxygen extraction even at high altitudes where oxygen is thin. This system is more efficient than mammalian lungs, compensating for low oxygen pressure without requiring larger lungs or reduced oxygen usage.

Stainless steel primarily contains iron, chromium (which provides corrosion resistance - at least 10.5%), and often nickel for additional properties. Tungsten is not a standard component of stainless steel - it's used in tool steels and high-speed steels for hardness, heat resistance, and wear resistance, but not in corrosion-resistant stainless steels.

Synclines are downward-arching folds in rock layers (U-shaped) formed by crustal compression, where tectonic forces push rock layers together horizontally. Unlike rifting (tensional forces pulling apart) or faulting (fracture and displacement), compression causes bending and folding without breaking, creating alternating synclines and anticlines.

Pediplains (broad, gently sloping erosional surfaces) and inselbergs (isolated resistant rock hills standing above the pediplain) are characteristic landforms of the arid cycle of erosion. They result from prolonged weathering and sheet erosion in arid and semi-arid environments where chemical weathering and mechanical processes work together over long periods.

Diastrophism, folding, and warping are all processes of crustal deformation involving rock bending or warping under tectonic stress - they are similar processes of structural deformation. Exfoliation is a weathering process where outer rock layers peel off due to pressure release or thermal expansion - completely different from tectonic deformation processes.
