<h2>
Answer:</h2>
<u>c. Solstice</u> describes days when sun's rays directly hit Tropic of Cancer and Tropic of Capricorn.
<h2>
Explanation:</h2>
The solstices occur due to the declination of the Earth's orbital movement around the sun. During this declination, the axial tilt is 23.5°. Furthermore, solstice's occurrence is during time the sun's direction is overhead the moon.
In Northern hemisphere, the declination is towards Tropic of Cancer with the axial tilt of 23.5°N. It occurs on June 20 & 22 while in the south the normal period of occurrence is between December 20 and December 23. In the south, the solar declination hits Tropic of Capricorn at 23.5°S.
Answer: Thermal inversion
Explanation: Thermal inversion or change the position of the air layer, when the warmer layer of air is above the cold layer, which is usually not the case. It happens due to a change in the normal temperature gradient, i.e. when the gradient becomes inverted. Such thermal inversions can occur in oceanic areas with a lot of upwelling near the coasts. Thermal inversion also occurs when sun radiation is less than radiation from the earth, which is the case during the night. The significance of these inversions is great, especially for air quality in polluted environments such as urban. The strongest inversions are during the winter and can then be dangerous due to poor air quality, which is measured by the AQI (Air Quality Index). The higher the AQI index, the greater the risk of bad air, that is, the worse air.
Answer:
Growth stage
Explanation:
The Growth stage -
Fire begins with a growth period which either transits to a rapid flashover period or, if that stage is not reached , starts to decay and fire ends . Growth phase is usually defined as the preflashover stage. Traditionally , compartment fires are either a fuel-controlled or ventilation controlled .
Fuel controlled fire is when the oxygen is available to combust all available fuel vapors in enclosure . Whereas ventilation controlled fire is when there is no enough oxygen to combust all the fuel available inside the enclosure.
Answer:
All types of faults generates earthquake
Explanation:
A fault is refers to a curved fracture in the rocks of the earth crust. It occurs when compressional and tensional forces causes displacement of the rocks on opposite side of the fracture. It is the fracture zone between two blocks of rocks. The energy released with rapid movements on active faults is the cause of most earthquakes. Basically, faults are crack in the earth's crust.
