What are the limited elements in the biosphere? The changes that particular elements undergo as they pass back and forth through the various earth systems (e.g., the biosphere) and particularly between living and non-living matter. The elements involved in biogeochemical cycles are hydrogen, oxygen, carbon, nitrogen, phosphorus, and sulfur. What is the limit of Biosphere? […]

Does it take much energy to produce steel? Energy is given in units of Joules × 109 per metric ton of steel produced. From the data in Table 1 and Fig. 3 it is apparent that the production of hot metal or pig iron is the most energy intensive process for steel production at roughly […]

What are some natural causes of weathering? Plant and animal life, atmosphere and water are the major causes of weathering. Weathering breaks down and loosens the surface minerals of rock so they can be transported away by agents of erosion such as water, wind and ice. What are some examples of weathering in nature? Some […]

What is the inner and outer crust made of? The inner core is solid, the outer core is liquid, and the mantle is solid/plastic. This is due to the relative melting points of the different layers (nickel–iron core, silicate crust and mantle) and the increase in temperature and pressure as depth increases. Which is the […]

What are the main function of fibrinogen? Fibrinogen (factor I) is a glycoprotein complex, made in the liver, that circulates in the blood of all vertebrates. During tissue and vascular injury, it is converted enzymatically by thrombin to fibrin and then to a fibrin-based blood clot. Fibrin clots function primarily to occlude blood vessels to […]

What are two landforms associated with wave action? It can create unique landforms, such as wave-cut cliffs, sea arches, and sea stacks. Deposits by waves include beaches. What landforms are created by waves? Coastal landforms are created by waves and include stacks, stumps, caves, arches, bays, coves, beaches and cliffs. Cliffs are vertical or near-vertical […]

What are the two ingredients of clouds? There are two ingredients needed for clouds to become visible; water, of course, and nuclei. Are clouds actually Fluffy? When warm air rises from the ground, it carries water vapor with it. When the water vapor meets the cold air found high in the sky, the gas condenses […]

Why bryophytes are called first land plants? Bryophytes are the group of plants that are the closest extant relative of early terrestrial plants. The first bryophytes (liverworts) most likely appeared in the Ordovician period, about 450 million years ago. This compelling fact is used as evidence that non-vascular plants must have preceded the Silurian period. […]
