What directly influences deepwater currents? temperature and pressure salinity and wind temperature and salinity wind and pressure

Answer;

Temperature and salinity

Explanation;Differences in the density of water can cause currents to form and move. Density is affected by temperature and salinity. Cold water or water with dissolved salts (higher salinity) is denser than warm water or water without dissolved salts. The different densities cause the water to move, forming a density current. In the oceans, the deep,bottom currents are colder and saltier than the surface currents.

Genetic engineering is the answer.

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
