Answer:
Option (3)
Explanation:
Springs (hot springs) and geysers are formed when the water from the interior of the earth are ejected into the earth's surface. In simple words, these are formed in the region where the groundwater and the ground surface intersects with each other.
The water obtained from springs can be cold or hot. Those that produce hot water are termed as hot-spring. These hot springs and geysers indicates the occurrence of volcanic activity. This water becomes hot due to the interaction with the magma at certain depths below the ground surface.
The geysers are also a type of hot-springs which produces hot water.
Thus, the correct answer is an option (3).
Well basically the earth turns on it,s surface
It constantly moves to readjust the position of the eye.<span>It constantly moves to maintain a steady point of fixation.</span>
Osmosis
Osmosis is movement of a solvent, across a semi-permeable membrane.
Answer: Winds are primary energy source for currents that flow horizontally in the ocean surface layers (less than 100 to 200 m deep). Hence surface currents often called “wind driven currents” or “wind drift currents”.
Currents that flow deep in the oceans below the level affected by winds are generated by convection caused by variations in water density. Higher-density waters sink and displace (push aside or up) less –dense water. Because density is determined by temperature and salinity, deep-water circulation is called “thermohaline circulation”.
The winds are the primary source for both ‘wind driven circulation’ and ‘thermohaline circulation’ is the sun. Winds are generated by the density variations in the earth’s atmosphere caused by solar heating and radiative and evaporative cooling.
Thermohaline circulation is driven by density difference between ocean water masses caused by temperature and salinity variations.
Explanation:
This is the main cause to form a wave over the sea surface.
