Dark surfaces are the best.
any surfaces really! just not rough stuff like sandpaper!
To reduce friction, which is a resistance between two surfaces in contact. The points of contact between moving parts in a machine create heat (which is actually a desired effect in a flintstone, in which one strikes a flintstone with another rock to create heat as a means of starting a fire) and cause damage in their grinding against one another. Oil reduces the friction, which reduces the heat generated and the damage from the moving part surfaces grinding against one another; this reduction in friction is called lubrication.
The best way to make homemade clay firm is to heat it up. You can heat the clay up in an oven.
Hot gluing is used lots in arts and crafts. Also, minor repairing of laminated surfaces around the home. Be careful when gluing surfaces that can melt with high heat, like Styrofoam - best to use regular glue for that. Just a added note: I have received gifts (a bird house) that was put together with hot glue, it fell apart. there are better glues out there. Depending on the use and the material you are gluing, consider handling, indoor, outdoor, etc. Good-Luck!
Cleavage is the splitting of rocks or minerals along defined surfaces.
Black surfaces with large area absorb heat best (a powder for example that is black).
black dull surfaces but im looking for why these surfaces are the worst?
smooth, dark colored
Dull Black Surfaces
NO! Ideal materials for radiating heat are black. If a body is radiating lots of heat then its electromagnetic(EM) spectrum should peak below the visible range(Infrared region),making the material look dark.
green
That's a dum Question , but it's black,blank,surfaces(usually)
Land surfaces heat up and cool down faster than water surfaces.
This cycle is known as the greenhouse effect
All surfaces absorb some heat.
White surfaces reflect light and heat. Black surfaces do not reflect light and they absorb heat.White surfaces reflect light and heat.

Clouds do not heat the earth though they can reduce heat radiating to space.
