Earth Sciences

Flat maps, unless they focus on polar regions, do not adequately depict the Antarctic continent (or the Arctic).

Because a flat map usually shows latitudes as lines parallel to the floor, and because there is no commerce or commercial value in Antarctica, the continent is depicted as a series of white, glacial continent edges at the bottom of the map. (This is especially true in northern-hemisphere-centric maps.)


Actually, Antarctica is a more-or-less circular continent, with a long arm (peninsula) that points to South America. It is about the same size as US and Mexico combined and occupies 10% of the earth's surface.


Here is a map:

Fibrinogen is converted into fibrin during the blood clotting process. This conversion is catalyzed by the enzyme thrombin, which cleaves specific peptide bonds in fibrinogen to form fibrin monomers. These monomers then polymerize to form a mesh-like structure that helps to stabilize the blood clot.

Long Answer:

Nobody knows. Humans didn't exist since the Earth began and we didn't start to think about that until thousands of years into our evolution. It is impossible to know how many seconds because the number would be so long it would stretch the entire planet of Jupiter 600,000,000,000,000,000,000,000,000 times. No exaggeration.

Short answer:

nobody could ever know.

Well, there are 60 seconds in a minute. There are 60 minutes in an hour. 60 times 60 is 3600. There are 24 hours in a day. 3,600 times 24 is 86,400. There are 365 days in a year. 86400 times 365 is 31,536,000. The Earth has been around for 4,600,000,000 years. 4,600,000,000 divided by 4 (to account for leap years) is 1,150,000,000. 366 times 86,400 is 31,622,400. 1,150,000,000 times 31,622,400 is 36,365,760,000,000,000. 4,600,000,000 minus 1,150,000,000 is 3,450,000,000. 3,450,000,000 times 31,536,000 is 108,799,200,000,000,000. 108,799,200,000,000,000 plus 36,365,760,000,000,000 is 145,164,960,000,000,000. So we can assume that plus or minus some few trillion, the Earth has been around for about 145,164,960,000,000,000 seconds. That is a lot of seconds. =D all a lie (^_^)

Well, honey, that question is a hot mess. I'm assuming you meant "212 degrees Fahrenheit at which water boils." But next time, how about using some actual words so I don't have to play guessing games?

Oxygen is a chemical element with the atomic number 8, which means it has 8 protons in its nucleus. The most common isotope of oxygen, oxygen-16, has 8 neutrons in its nucleus as well. Therefore, oxygen atoms are primarily composed of 8 protons and 8 neutrons in the nucleus, surrounded by 8 electrons orbiting the nucleus in energy levels.

Well, honey, eggs are technically considered a producer in the food chain because they come from chickens, which are living organisms that produce them. So, in the grand scheme of things, eggs are at the start of the food chain, not chomping down on other critters like a consumer would. Hope that clears things up for you, darling!

Well, darling, fresh aluminum has a shiny metallic luster. It's like a mirror reflecting your fabulous self back at you. Just make sure to keep it clean, unlike your ex's act.

The amount of ore needed to extract one ounce of gold can vary depending on the concentration of gold in the ore. On average, it typically takes about 2.3 tons of ore to extract one ounce of gold. This ratio is known as the ore grade and is an important factor in determining the economic viability of gold mining operations.

Calcareous ooze is a type of deep-sea sediment primarily composed of the mineral calcite, which is derived from the shells of marine organisms like foraminifera and coccolithophores. Siliceous ooze, on the other hand, is composed of silica-based minerals such as opal, originating from the silica skeletons of diatoms and radiolarians. The main difference between the two lies in the mineral composition, with calcareous ooze being calcite-based and siliceous ooze being silica-based.

The increasing presence of carbon dioxide in the atmosphere is contributing to the acidification of the oceans by causing more CO2 to dissolve in seawater, forming carbonic acid. This acidification can harm marine life, especially organisms like corals and shellfish that rely on calcium carbonate to build their shells and skeletons.

When water evaporates, it leaves behind impurities and minerals that are not volatile enough to evaporate with the water molecules. This process is known as distillation, where water is separated from its impurities through evaporation and condensation. The impurities are left behind as residue or sediment, while the purified water vaporizes and forms clouds in the atmosphere before eventually condensing back into liquid form as precipitation.

Carbon dioxide in the atmosphere is measured using a variety of methods, including ground-based monitoring stations, satellite observations, and air sampling. Ground-based stations use instruments like gas analyzers to measure CO2 levels directly in the air. Satellites can also measure CO2 concentrations from space by analyzing the sunlight reflected off the Earth's surface. Air sampling involves collecting air samples in containers and analyzing them in a laboratory to determine CO2 levels accurately. These methods help scientists track changes in atmospheric CO2 levels over time and understand its impact on the environment.

chalk is an insulator because heat does not flow through it as easily.

The sky appears yellow when it rains because of the way sunlight interacts with water droplets in the atmosphere. The sunlight gets scattered by the water droplets, causing the sky to take on a yellowish hue.

Oh, dude, the likely minimum height of the storm surge at Tampa, Florida on the afternoon of Sept 14 was probably around 2-4 feet. But hey, I'm not a weatherman or anything, just a guy making jokes. So, like, don't quote me on that for your next science project, okay?

Contour interval is the actual change in elevation represented by the space between two adjacent topographic "rings". For example, if there is a contour interval of 20 feet, each topographic line on the map represents going either up or down by 20 feet of elevation (and sometimes it's hard to tell which).

For convenience, many mapmakers include numbers every four or five lines to tell you what elevation is represented by that line.

The substance that attracts and holds the most energy is uranium-235. Uranium-235 is a fissile isotope that can undergo nuclear fission, releasing a tremendous amount of energy in the form of heat and radiation. This energy release is the basis for nuclear power plants and nuclear weapons.

Oh, dude, like, soil erosion is all about gravity, water, and wind, right? So, like, areas with steep slopes and heavy rainfall would totally be the hotspots for soil erosion. It's like nature's own little car wash for the earth, but way less fun.

If earth has 196,940,400 square miles of total surface area (land and water) as most of the websites indicate (some websites say 196,935,000 square miles). Multiply by 5,280 squared: 5,490,383,247,360,000 square feet (Or if the other websites are correct: 5,490,232,704,000,000 square feet) In any event, a little less than 5-1/2 quadrillion square feet. ===== As an aside, the largest body in the solar system (the Sun): Approximately 864,000 miles in diameter according to most sources. Comes out to 2,345,184,368,640 square miles of _extremely_hot_ 'surface' area. Or, a little more than 2-1/3 trillion square miles. Square feet? Try 65,379,987,902,693,376,000 square feet, (just as hot). Or, a little more than 65-1/3 quintillion square feet. Wouldn't be very much fun to count. Ugh! Get me some water!

The most vulnerable part of the Earth system is often considered to be the cryosphere, which includes ice sheets, glaciers, sea ice, and permafrost. These components are particularly sensitive to changes in temperature and can have significant impacts on global climate patterns. The rapid melting of ice in the polar regions, for example, can contribute to sea level rise and alter ocean circulation patterns, leading to far-reaching consequences for ecosystems and human populations around the world.

A steep face of a plateau is called a escarpment. An escarpment is a long, steep slope, especially one at the edge of a plateau or separating areas of land at different heights. It is typically formed by erosion or faulting processes over time.

Water is essential for sustaining life on Earth. It is crucial for various biological processes, such as hydration, digestion, and temperature regulation. Without water, living organisms, including humans, plants, and animals, would not be able to survive.

Sinkholes are repaired by filling them with materials like concrete, grout, or soil to stabilize the ground. Common methods include injecting grout to fill voids, excavating and refilling the sinkhole, or using soil stabilization techniques. These methods help prevent further collapse and restore the area's stability.

Ultramafic rocks form in the Earth's crust in the upper mantle, specifically in the mantle portion known as the asthenosphere. These rocks are composed primarily of minerals rich in magnesium and iron, such as olivine and pyroxene. Ultramafic rocks are brought to the Earth's surface through processes like volcanic eruptions or tectonic movements, providing valuable insights into the composition and dynamics of the Earth's interior.

The most effective plants at absorbing carbon dioxide include bamboo, pine trees, rubber trees, and mangroves, along with fast-growing species like Paulownia. Additionally, algae, seagrasses, and phytoplankton play a crucial role in CO₂ absorption, significantly aiding in carbon sequestration.
