Friction is a force that resists against two surfaces sliding across each other. The rougher the surfaces are the more friction they will encounter, and the smoother the surfaces the less friction there will be.
Friction is a very important force, and many of your day to day activities rely on friction. You walk around easily because of the friction between the ground and your feet. When you are on a low-friction surface like ice you will find it hard to walk, and you are likely to fall over.

Scientific name: chlamydosaurus kingii
The frill necked lizard, frilled lizard or frilled dragon is found in dry regions of Australia and New Guinea. It can grow to a metre long including its tail. The lizard has a large frill around its neck that it can raise when it is disturbed, and the frill is meant to frighten off whatever disturbed it. If the frill doesn't work it will run away and hide up a tree.
Frill neck lizards eat insects and small lizards.
