 * =Turbid (muddy) water heats up more quickly than clear water.=
 * =Cutting trees along river banks raises water temperature.=

WATER TEMPERATURE
1. IS ALL WATER THE SAME TEMPERATURE? A&B: It depands on the sun,current and the deep of the water.If the sun is direct to all parts of the water in the river which a river, which the deeper area the water is cooler and the shallow water is warmer. 2. is a lake the same temperatureas a river? A&B: No because the deep end in the lake is different from a river and there is no current in a lake. So their temperature cannot be the same 3. is a ocean the same temperature as a river? A&B: No because the deep and salt in the ocean. Ocean water is containing more salt than the water in the river so their temperature must be different. 4.Are there times when a lake or river might be cooler or warmer? A&B: Yes, in day time the water in a river might be cooler, because the water in the river is deeper. But at night timme or winter the water in the cooling faster than in a river. Because the water in the lake is shallow, so it conducts heat/cold faster than the water in the river. internet info What happens when the temperature rises? the fish cannot reproduce. What happens when it falls ? If the temperature drops to low some marine life will die. How do these affect life in the river?why? the number of marine life will decrease, because they are unable to repodu﻿ce if it,s to hot or cold
