Easy Mind MapsLakes are significant water bodies formed by geological or human activities and can be freshwater or saltwater. They support biodiversity, regulate climate, and provide water resources. Major lakes include the Caspian Sea and Lake Baikal. Threats like pollution and climate change endanger them, necessitating conservation efforts for sustainability.
El Niño and La Niña are climate phenomena linked to Pacific Ocean temperature changes, influencing global weather patterns, agriculture, and economies. El Niño warms the Pacific, causing weak monsoons and droughts, while La Niña cools it, resulting in strong monsoons and floods. Understanding these phenomena aids in climate prediction and disaster preparedness.
Ocean temperature is the heat content of seawater, influenced by factors like sunlight, depth, and currents, affecting marine life and climate. The average ocean surface temperature is about 16°C. Rising temperatures lead to coral bleaching, melting ice, and extreme weather, highlighting significant environmental concerns.
What is Salinity? 📌 Fact: Dead Sea has one of the highest salinities (~330‰), allowing people to float easily! Composition of Sea Water 🌊 Component Percentage (%) Water (H₂O) 96.5% Sodium Chloride (NaCl) 2.7% Magnesium, Calcium, Potassium, Sulfates 0.8% 📌 Fact: Salt in oceans comes from weathering of rocks, river runoff, and volcanic eruptions. Factors […]
Oceans cover 71% of Earth’s surface and play a vital role in climate regulation, biodiversity, and global trade. There are five major oceans: Pacific, Atlantic, Indian, Southern, and Arctic, each with unique features. Threats like pollution and climate change necessitate conservation efforts for their protection and sustainability.
Groundwater, a critical freshwater resource, is stored beneath the Earth and is primarily replenished by rainwater. It supports drinking water, agriculture, and industry, but faces threats from overextraction and pollution. Sustainable conservation practices, such as rainwater harvesting and drip irrigation, are essential for its preservation and management.
What is the Hydrosphere? Components of the Hydrosphere Component Description Percentage of Earth’s Water Oceans & Seas 🌊 Largest water bodies (saltwater) 97% Ice Caps & Glaciers ❄️ Frozen water in polar regions & mountains 2% Groundwater 💦 Water stored underground 0.7% Rivers & Lakes 🏞️ Freshwater sources on land 0.3% Atmospheric Water ☁️ Water […]
Climate refers to long-term weather patterns, influenced by factors such as latitude and altitude. The Köppen Climate Classification categorizes climates into five main types: Tropical, Dry, Temperate, Continental, and Polar, each with subcategories. Understanding these classifications aids in fields like agriculture and environmental science, impacting human settlements and ecosystems.
Cyclones are low-pressure systems that bring storms, heavy rainfall, and strong winds, rotating counterclockwise in the Northern Hemisphere. Anticyclones, on the other hand, are high-pressure systems associated with clear, dry weather and clockwise wind rotation. Both systems significantly impact weather patterns and environmental conditions globally.
Rainfall distribution describes how precipitation varies across the Earth, shaped by factors such as latitude, wind patterns, topography, ocean currents, and monsoons. This distribution influences agriculture, climate, and human settlements, with significant differences in rainfall across regions leading to diverse environmental effects, including floods and droughts.
