The difference between life insurance and burial insurance is that with life insurance, you agree to pay a fixed amount of money occasionally to an insurance company. On the other hand, with burial insurance, it is designed to prepay your funeral arrangements only as well as decreasing the burden of funeral planning for your relatives.

Sheilawangui's answer is right. But, here's some detail about them:

A regular life insurance policy is based on the likelihood you would die in any given year of your life, based on health and risky activities (smoking, motorcycles, skydiving...). These policies require a physical examination. The premium cost per $1000 benefit is less than a burial policy. BUT, if you are part of a 'group plan' (job, club membership etc) you skip the physical unless you ask for a large amount of insurance.

A burial policy is to help your family pay your final expenses like funeral, burial, last medical expense etc. It has higher premiums per $1000 benefit, but the rules on acceptance are relaxed somewhat, consisting of several health questions on the application form. BUT, if any answer to those health questions indicate health problems you go through a more involved physical examination, and may be turned down for the insurance.

If the insurance company finds that you were untruthful on your initial application, or if your death is due to risky behavior, or suicide, they don't pay.
