Answer:
Hydraulic engineering is just a part of civil engineering. It is based on flow and conveyance of fluids, mainly water and sewage. It can be seen as an application of fluid mechanics for taking care of problems arising during storage, transport, regulation, measurement and use of water. This is needed while designing dams, canals, or cooling water facilities for thermal power plants.
Answer:
B. Rays of sunlight hit less directly. The days are shorter and temperature colder.
Explanation:
When the north pole tilts away from the sun, the sun's rays are displaced below the equator line, that is, towards the southern hemisphere. It causes the northern hemisphere to receive fewer solar rays and to receive them indirectly, which leaves the atmosphere cooler and decreases the length of the day. This moment coincides with winter and autumn in the northern hemisphere. This inclination of the north pole lasts six months and after that period the moment of inclination of the south pole begins, which causes the sun's rays to be displaced towards the northern hemisphere.
