Fossil fuels, such as coal, oil, and natural gas, are formed from the remains of ancient plants and animals and take millions of years to form. Once they are used up, they cannot be replaced.

Solar energy, derived from the sun, is the primary source of energy for most living organisms. Plants use photosynthesis to convert sunlight into chemical energy, which is then passed up the food chain.

Wind is a renewable natural resource because it is constantly replenished by the movement of air. It can be harnessed to generate electricity through wind turbines.

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to produce glucose and oxygen. This process is essential for the survival of plants and provides the basis for the food chain.

Glaciers are major sources of freshwater for human consumption. They store large amounts of frozen water, which can be released as meltwater when temperatures rise.

Evaporation is the process by which water evaporates from the Earth's surface and condenses to form clouds. This process is driven by the sun's heat and is essential for the water cycle.

All types of rocks can contain mineral resources. Igneous rocks are formed from the cooling and solidification of molten rock, sedimentary rocks are formed from the accumulation and compaction of sediments, and metamorphic rocks are formed from the alteration of existing rocks due to heat, pressure, or chemical reactions.

Erosion is the process by which soil is eroded by wind or water. This can lead to the loss of valuable topsoil and can have negative impacts on agriculture and the environment.

Fossil fuels, such as coal, oil, and natural gas, are currently the major source of energy for electricity generation. However, there is a growing trend towards the use of renewable energy sources, such as solar and wind energy.

Transpiration is the process by which plants lose water vapor through their leaves. This process helps to regulate the plant's temperature and is essential for the movement of water and nutrients throughout the plant.

Deforestation, industrial activities, and agricultural practices can all contribute to pollution. Deforestation releases carbon dioxide into the atmosphere, industrial activities can release harmful chemicals and pollutants, and agricultural practices can lead to the release of fertilizers and pesticides into the environment.

Weathering is the process by which rocks are broken down into smaller pieces. This can be caused by physical processes, such as temperature changes and freezing and thawing, or by chemical processes, such as the action of acids and bases.

Plants, animals, and fish are all major sources of food for humans. Plants provide us with carbohydrates, fruits, vegetables, and grains, while animals and fish provide us with protein, fats, and essential nutrients.

Deposition is the process by which sediments are deposited and accumulate. This can occur when the velocity of a fluid (such as water or wind) decreases, causing the suspended sediments to settle out.

Solar energy is a major source of renewable energy. It can be harnessed using solar panels, which convert sunlight into electricity. Solar energy is clean, sustainable, and has the potential to provide a significant portion of our energy needs.
