Option D is correct.
d. have the same movement as thermohaline currents
The movement of the surface water of the ocean due to the certain pattern of wind and Coriolis Effect and earth spin creates surface currents. That are influenced by all of the above three except the fourth one.
Option D is correct.
d. triangle
Water molecules are not linear in shape. Oxygen has 8 electrons in its valence shell so there are two bonding pairs in water and two lone pairs. Lone pairs strongly repel each and water molecules get bent shape due to this.
Option C is correct.
c. oceans
We just do not know that how much heat is captured in the oceans. Most of the heat dissipates in the atmosphere is absorbed in the oceans. So, most of the heat is retained in oceans.
Option B is correct.
b. in the equatorial region
Hurricanes begin as the warms storms in tropical regions of due to the warm moist water of Atlantic and Pacific Oceans near the equator. So the correct option is B.
The odd statement is b. exist in large lakes
Surface currents are generated largely by wind. Their patterns are determined by wind direction,Earth's rotation, and the position of landforms that interact with them. Currents may also be generated by density differences in water masses caused by temperature and salinity variations but they are not present in the form of lakes
The shape of H2O molecule is oval
It is not completely oval but irregular A molecule of water has an angular or bent shape. The H-O-H bond angle in a molecule of water is 104.5o, an angle that is also quite close to the 109.5o bond angles of methane so we can say that it is a little bit oval plus triangular too.
Much of the earth's heat is retained in the oceans
Earth retains its temperature in water cycle and we know that water cycle is mostly dependent upon the ocean. Although winds are also responsible but mostly it is retained by oceans. Similarly the constant exchange of energy between the Earth's surface and the greenhouse gases is what enables the planet to maintain its average temperature of 15 degrees Celsius.
Most hurricanes will originate in the equatorial region
A hurricane needs the warm water of the tropics, which feeds a storm with energy, in order to form. Most of them are originated in the African continent and that is why we can say that they originate from the equatorial region because much part of Africa lies in equator.
