Villa Epecuén, a resort town located 340 miles (547 km) southwest […]
Scientists at the US National Climatic Data Center measure the Earth’s surface temperature each month and compare it to the previous century’s average to detect climate change trends. Every month since February 1985 has had above-average temperatures, providing evidence of climate change. The average temperature on the surface of the Earth is measured each month […]
Northeast Greenland National Park is the largest protected park on Earth, covering 357,917 square miles and containing 40% of the world’s musk ox population. It is located in the Arctic and home to various animal species. The largest protected park on Earth is Northeast Greenland National Park, which is approximately 357,917 square miles (927,000 square […]
Earth’s human population was less than 26,000 for a million years, with only 18,500 able to reproduce, making humans an endangered species. Genetic studies suggest various events, including a super volcano eruption, caused the low numbers. According to scientists at the University of Utah, Earth’s entire human population was less than 26,000 for about a […]
A vegan diet could reduce food-related greenhouse gas emissions by 70% by 2050, preventing 8.1 million human deaths and saving billions in healthcare costs, according to a 2016 study by Oxford University researchers. Vegans do not eat animal products, including dairy, eggs, cheese, honey, leather, fur and wool, and get protein from sources such as […]
Urban areas hold over 50% of the world’s population despite covering only 1.5% of the earth’s surface. With 8 billion acres of arable land, there is enough land for each person to have 4 acres if the population reaches 9 billion by 2050. Although urban areas represent only 1.5% of the earth’s surface, they contain […]
Vredefort Crater is the largest verified asteroid crater in the world, located in South Africa, while Wilkes Land Crater may be larger but is yet to be verified. Vredefort is approximately 186 miles in diameter, 3 miles deep, and 2 billion years old. Wilkes Land is said to be 300 miles in diameter and located […]
Earth Day is an annual event celebrated globally to promote environmentally healthy practices. It is celebrated on April 22 or during the vernal equinox. Early celebrations focused on highlighting environmental problems, while modern celebrations focus on progress made in research and education on sustainable living. Earth Day has become widely known, with more nations and […]
Earth Hour is an annual event where participants turn off non-essential lights for an hour to raise awareness about wasted electricity. The event began in Sydney in 2007 and has since spread globally. Critics argue that the reduction in energy use during the hour is insignificant, but participants hope to encourage continued energy conservation throughout […]
A convex ground blade is a durable knife grind that curves outward, making it ideal for heavy chopping and slicing. It requires a skilled metalworker and special sharpening skills, but if well cared for, it can serve the owner well. Cleavers and axes are often made with convex ground blades. Cooks should take care to […]
Molten earth is a fast-setting building material made from earth and plaster of Paris, poured into molds to create walls. It provides excellent insulation and can be customized with colors and textures. However, it may pose challenges for building codes, so consultation with inspectors is recommended. Molten earth is a building material made from a […]
Earth dams are embankment-type dams made of compacted earth, rock, and clay. They are cost-effective and can be designed with drainage layers, but can also be a safety concern if poorly engineered. Routine inspection and maintenance are necessary. They can be used for hydroelectric power, water supply, and flood control. An earth dam is a […]
Himmel und Erde is a German dish featuring apples and potatoes, often served with meat or as a vegetarian option. Spices like nutmeg are added, and the two main elements are boiled separately to bring out their flavors. It can be served as a side dish or a full meal. Himmel und Erde is a […]
Google Earth is a mapping program that uses satellite imagery and aerial photography to create a 3D map of the world. Users can explore virtually any area on Earth, and there are two versions available: a free version and a pro version for large companies. The newest version, Earth 5.0, has educational features, including historical […]
Earth science covers climate, geological processes, water cycle, and different climates. Lab activities can help students understand concepts such as tectonic plates, soil strata, the water cycle, and the moon’s effect on tides. Candy, terrariums, and group activities can be used in labs. Earth science is the study of the Earth and all its rhythms. […]
Earth science, also known as geoscience, encompasses various subfields such as geology, atmospheric science, meteorology, and oceanography. Geology analyzes materials like rocks and sand, while atmospheric science studies the atmosphere and related factors. Meteorology focuses on climate-related issues, and oceanography studies the planet’s bodies of water, including marine and freshwater habitats. Students learn about the […]
Earth science studies the tangible attributes of the planet, including geology, soil science, geography, oceanography, and atmospheric sciences. Geology analyzes the rocky aspects of the planet, while oceanography studies the marine ecosystem and its components. Atmospheric sciences focus on the behavior of the atmosphere, with meteorology predicting weather patterns. Just as the name suggests, earth […]
The earth sciences include geology, oceanography, meteorology, and astronomy. Astronomy studies things outside Earth’s atmosphere and affects life on Earth in various ways, including planetary temperature and ocean tides. The relationship between space and earth sciences is fundamental for the support of animals and vegetation, as the Sun’s energy is necessary for life. The moon […]
During the last ice age, large parts of the world were covered in ice sheets, while alpine glaciers carved out valleys and ribbed patterns. Glaciers also formed many of the features in places like Yosemite Valley, making them ideal for rock climbing. Fjords in northern countries like Canada, Norway, Iceland, and Greenland were also formed […]
