Evidence can be found in many ways, witnesses, marks on a body (if its a murder), finding the person who caused the scene, fingerprints, it really depends on what the issue is like is it murder. Something was stolen.
<span> Advantages
- large resource of potential oil
- biggest resource is in Canada, whereas the largest reserves of crude oil are in Saudi Arabia and Venezuela
</span><span><span>- It requires less processing than oil shale and presents fewer problems than oil shale
- Processing is mainly by hot water.</span>- Exploitation has only started recently so low cost reserves are still available.
Disadvantages
- Most of the resource is uneconomic at present oil prices - so exploitable reserves are less than for crude oil
- Oil sands require mining, which is more complex and costly than drilling and pumping crude oil.
- Processing requires more energy than for crude oil.
- Resources are less than for oil shale - which is available in very large reserves in the US and Australia.</span>
<span>- Refining is more difficult because the product is in the form of bitumen - requiring cracking to produce a saleable product.
- because of the increased processing and refining, more carbon is released per unit of useable energy than for crude oil</span>
