What are the elements of Geosphere? The geosphere has four subcomponents: lithosphere (solid Earth), atmosphere (gaseous envelope), hydrosphere (liquid water), and cryosphere (frozen water) (fig. What is the function of geosphere? Geo means “earth.” The Earth’s geosphere (sometimes called the lithosphere) is the portion of the earth that includes rocks and minerals. It starts at […]
Which is a significant benefit of studying fossils?
Which is a significant benefit of studying fossils? By studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other. Often we can work out how and where they lived, and use this information to find out about ancient environments. Fossils […]
Is there a rational number between every irrational?
Is there a rational number between every irrational? Between two rational numbers there is an irrational number. Between two irrational numbers there is an rational number. We can appeal to the decimal expansion of q −p to prove the existence of such an n. Is |- 3 an irrational number? Explanation: The definition of an […]
What is the dilution factor of 1 2?
How long can a car with a dead battery sit?
How long can a car with a dead battery sit? And what if your car won’t start because of a dead battery? It isn’t a far-fetched possibility, since high-tech vehicles that have computers on monitoring systems need recharging — and if left alone, the battery of such a vehicle could die in about two weeks. […]
How can pressure and flow rate be controlled?
How can pressure and flow rate be controlled? For every pressure, the pump will only deliver one specific flow rate. Therefore, to control the flow of a centrifugal pump, simply set the output pressure to the point on the P-V diagram that allows the pump to deliver the desired flow rate. The output pressure of […]
What is the first step in photosynthesis?
What is the first step in photosynthesis? The first stage of photosynthesis is called the light reactions. During this stage, light is absorbed and transformed to chemical energy in the bonds of NADPH and ATP. Is it true that only plants can make their own food? Green plants are the only organisms in the world […]
Is pressure stored energy?
Is pressure stored energy? Pneumatic – energy is stored within pressurized air. Air under pressure, can be used to move heavy objects and power equipment. object and its distance from the ground when it is put in motion. The heavier the object, and the further it is from the ground, the greater its gravitational energy. […]
Which elements can have more than 8 valence electrons?
Which elements can have more than 8 valence electrons? Unlike atoms from periods one and two that only have the s and p orbitals (total of 8 valence electrons), atoms like phosphorus, sulfur, and chlorine can have more than 8 electrons because they are not restricted to the s and p orbitals and have a […]
What do plants and animals have in common?
What do plants and animals have in common? Animal cells and plant cells share the common components of a nucleus, cytoplasm, mitochondria and a cell membrane. Plant cells have three extra components, a vacuole, chloroplast and a cell wall. What do plants and animals not have in common? As plants and animals are eukaryotic, so […]
