B) convection
Explanation:
Once the sun's energy reaches the earth's atmosphere by radiation, it is circulated within the atmosphere and oceans through convection.
The energy of the sun on earth is moved between the ocean and the atmosphere by air around us.
- Heat transfer in fluids is by convection.
- It involves the actual motion of the particles of medium from one place to another due to differences in temperature and density.
- Air close to the surface of the ocean is less dense and hot due to high temperature.
- The air rises and it is replaced by colder air masses.
- This exchange leads to the development of convective cells.
- This moves the energy of the sun between the atmosphere and the ocean surface.

Answer:
The required volume of hexane is 0.66245 Liters.
Explanation:
Volume of octane = v=1.0 L=
Density of octane= d = 
Mass of octane ,m= 
Moles of octane =
Mole percentage of Hexane = 45%
Mole percentage of octane = 100% - 45% = 55%
Total moles = 11.212 mol
Moles of hexane :
Moles of hexane = 5.0454 mol
Mass of 5.0454 moles of hexane,M = 5.0454 mol × 86 g/mol=433.9044 g
Density of the hexane,D = 
Volume of hexane = V
(1 cm^3= 0.001 L)
The required volume of hexane is 0.66245 Liters.
Answer: 1. 3.914 × ^10-4 | 2. 4.781 × ^10-1
Explanation:
Answer:
The correct answers are:
• Softer, porous, or more permeable rocks weather faster than harder rocks.
• Rocks in warmer climates weather faster than rocks in colder climates.
• The more water present, the faster the rate of weathering.
Explanation:
Weathering is the process through which the surface minerals of rock are broken down and loosened. This occurs through the action of extreme temperatures, rainwater and biological activity.
Hope this helps- Good luck ^w
