Which causes the thermocline?
Igoryamba
<span>Thermocline is a layer between warm water from the ocean’s surface and cool water from below the ocean. In here, the temperature decreases rapidly from the warmer layer to the colder layer.  A thermocline forms due to the heat of the sun heating the ocean’s surface. Because of the difference in density between warm and cooler ocean water, cooler ocean water sinks and warmer ocean water floats. This is caused due to the heat and mass transfer between particles of the ocean. The answer is letter C. The sun’s radiation does not extend below a certain depth; therefore, deeper ocean water is colder than surface water.</span>

icang [17]

Answer:

primary advantage of composite material are high strength, low weight, corrosion resistance

Explanation:

The primary advantage of composite material is

1) high strength - they are stronger in strength than commanly used material like steel and aluminium.

2)low weight - lighter than most of the material like woods and others metals

3) corrosion resistance - it resist extreme condition of weather and can be good place where handling of chemicals takes place.

Sati [7]

Answer:

2.11 seconds

Explanation:

We use the kinematic equation for the velocity in a constantly accelerated motion under the acceleration of gravity (g):

v_f=v_i-g*t\\-5.2 = 15.5 - 9.8\,t\\9.8 \,t= 15.5 + 5.2\\t = 20.7/9.8\\t = 2.11 \,\,sec
