What is the difference between microstructure and phase? a) What is the difference between a phase and a micro constituent? (a) A “phase” is a homogeneous portion of the system having uniform physical and chemical characteristics, whereas a “micro constituent” is an identifiable element of the microstructure (that may consist of more than one phase). […]
What are the 6 main climate zones?
What are the 6 main climate zones? There are six main climate regions: tropical rainy, dry, temperate marine, temperate continental, polar, and highlands. What are the main climate zones? The Earth has three main climate zones: tropical, temperate, and polar. The climate region near the equator with warm air masses is known as tropical. What […]
How are the properties of waves related?
How are the properties of waves related? All kinds of waves have the same fundamental properties of reflection, refraction, diffraction and interference, and all waves have a wavelength, frequency, speed and amplitude. A wave can be described by its length, height (amplitude) and frequency. All waves can be thought of as a disturbance that transfers […]
Where is the highest amount of net radiation found?
Where is the highest amount of net radiation found? For all surfaces, the net radiation is greatest when the sun is shining between clouds and is larger under an overcast sky than it is when the sun is near the horizon. What is the difference between incoming and outgoing radiation? Based on the physics principle […]
Do structural engineers make a lot of money?
Do structural engineers make a lot of money? While a civil/structural engineer can average a salary of $79,902 per year, or $38.41 per hour, there are many opportunities for civil/structural engineers to make more. For example, in San Francisco, CA you might make $93,540 per year. Other high-paying locations include Tulsa, OK, Huntsville, TX and […]
How is glass made naturally?
How is glass made naturally? In nature, glasses are formed when sand and/or rocks, often high in silica, are heated to high temperatures and then cooled rapidly. The Glass in Nature display shows specimens of glass made in nature. Obsidian or volcanic glass, for example, is molten rock that has quickly cooled, becoming rock in […]
How does a step up transformer increase potential difference?
How does a step up transformer increase potential difference? A step-up transformer changes a voltage into a larger voltage. A step-down transformer changes a voltage into a smaller voltage. For both transformers, a magnetic field is induced in the iron core which impels this voltage change. What are the advantages of using a transformer in […]
How does a low pressure system form?
How does a low pressure system form? Low-pressure systems form under areas of wind divergence that occur in the upper levels of the atmosphere. Diverging winds aloft ahead of these troughs cause atmospheric lift within the troposphere below, which lowers surface pressures as upward motion partially counteracts the force of gravity. Does high pressure or […]
How do flowers benefit from bees?
How do flowers benefit from bees? Flowers rely on bees to cross-pollinate their female plants. When bees feed on the pollen, their body picks up excess via their pollen-collecting hairs, which is then released when they land. Pollen act as the flower’s seed, which is mandatory for the survival of that flower species. What are […]
What affects wind patterns?
What affects wind patterns? On Earth, global wind patterns are influenced by several factors: First, the planet’s rotation creates counterclockwise low pressure cell rotations in the Northern hemisphere and corresponding clockwise rotation in the Southern hemisphere (the coriolis effect). What are the local factors affecting the wind? Factors affecting Wind Movement Wind == horizontal movement […]
