If they built a pipeline from the ocean and pumped sea water into the dry lakes of Australia, the water would

Question

water would evaporate, would it come down as rain?

Can you think of a better way to make it rain?

Answer 1

Nice idea, but you sure would have lots of salt and who knows where the moisture would go. It takes much energy to move the saltwater into the dry lakes.

Answer 2

"Can you think of a better way to make it rain?"

Eh, irrigation channels are much more efficient than trying to make it rain ;D

"would it come down as rain?"

Eventually, but where it did so would be just about anybodies guess.

Answer 3

if u took water to a desert wolud it make rain or would the heat dry all the water up . my sreach shows this .The oceans cover ¾ of the earth’s surface and have great impact on the biosphere. The evaporation of these oceans is how we get most of our rainfall, and their temperature determines our climate and wind pattern. Life within the ocean had already evolved 3 billion years prior to the movement of animal and plant life on land. The amount of life and distance from shore (abiotic factor) effects the major distribution of marine biomes. Animals such as algae, branacles and muscles who live within the intertidal zone (land meets ocean) will fix themselves to rocks so they do not get washed from the resulting tides. The ocean is home to many species and consists of several other zones such as pelagic, benthic (sea floor), photic, and aphotic.[4].  AND this is on evaporate......Theory

For molecules of a liquid to evaporate, they must be located near the surface, be moving in the proper direction, and have sufficient kinetic energy to overcome liquid-phase intermolecular forces.[1] Only a small proportion of the molecules meet these criteria, so the rate of evaporation is limited. Since the kinetic energy of a molecule is proportional to its temperature, evaporation proceeds more quickly at higher temperature. As the faster-moving molecules escape, the remaining molecules have lower average kinetic energy, and the temperature of the liquid thus decreases. This phenomenon is also called evaporative cooling. This is why evaporating sweat cools the human body. Evaporation also tends to proceed more quickly with higher flow rates between the gaseous and liquid phase and in liquids with higher vapor pressure. For example, laundry on a clothes line will dry (by evaporation) more rapidly on a windy day than on a still day.Three key parts to evaporation are heat, humidity and air movement.

[edit] Evaporative equilibrium



Vapor pressure of water vs. temperature. 760 Torr = 1 atm.If evaporation takes place in a closed vessel, the escaping molecules accumulate as a vapor above the liquid. Many of the molecules return to the liquid, with returning molecules becoming more frequent as the density and pressure of the vapor increases. When the process of escape and return reaches an equilibrium,[1] the vapor is said to be "saturated," and no further change in either vapor pressure and density or liquid temperature will occur. For a system consisting of vapor and liquid of a pure substance, this equilibrium state is directly related to the vapor pressure of the substance, as given by the Clausius-Clapeyron relation:



where P1, P2 are the vapor pressures at temperatures T1, T2 respectively, ΔHvap is the enthalpy of vaporization, and R is the universal gas constant. The rate of evaporation in an open system is related to the vapor pressure found in a closed system. If a liquid is heated, when the vapor pressure reaches the ambient pressure the liquid will boil.

The ability for a molecule of a liquid to evaporate is largely based on the amount of kinetic energy an individual particle may possess. Even at lower temperatures, individual molecules of a liquid can potentially evaporate if they have more than the minimum amount of kinetic energy required for vaporization.

ok so basic depending on the heat and the amount it make rain But u still need alot of  k energy .
