There are three zones in flame, viz. outer zone, middle zone and inner zone.
Outer Zone: This zone is blue in colour. It is the hottest part of the flame, because complete combustion takes place in this zone.
Middle Zone: This zone is yellow and orange in colour. This zone is moderately hot because partial combustion takes place in this zone.
Inner Zone: This zone is dark in colour. This is the coolest part of the flame because no combustion takes place in this zone.

Rough surface has more irregularities which cause interlocking of the surfaces of the two objects which are in contact with each other.Friction is caused by the interlocking of irregularities which oppose the motion of the object.Thus the friction is greater if rough surfaces are involved.
Yogita Ingle 7 years, 2 months ago
Friction is always more on a rough surface compared to a smooth surface. This is because rough surface offers more resistance to the movement of an object over it compared to a smooth surface. So, rough surface have greater friction.

Disposing of waste has huge environmental impacts and can cause serious problems. Some waste will eventually rot, but not all, and in the process it may smell, or generate methane gas, which is explosive and contributes to the greenhouse effect. Leachate produced as waste decomposes may cause pollution. The environmental problems like global warming, acid rain, air pollution, urban sprawl, waste disposal, ozone layer depletion, water pollution, climate change and many more affect every human, animal, and nation on this planet.
