The geological conditions.
If a disconformity is present in a region then it is likely that the region experienced extensive and prolonged denudation. Denudation is the laying bare of the land by the processes of mass wasting, weathering and erosion. A disconformity is a type of unconformity involving a non-sequence of beds. Sedimentary rocks that were exposed to denudation over time has some strata removed and then has new strata deposited without a change in the underlying or subsequent overlaying rocks. This makes disconformities hard to identify.
YES.
The thirst mechanism always underestimates fluid loss during work, in the heat and after work ends. Therefore you should take frequent drinks through out the work period. If you drink 250mililitres every 15 minutes, you can replace one litre per hour. if sweat rate is higher you will find it extremely difficult to keep up with fluid needs. During prolonged periods of work in the heat, weight loss exceeds 2 percent therefore the person should rehydrate before returning to work.
Mostly through bites, I think.
They destroy things that cost lots of money to repair, or they put people in hospitals, and that would cost a lot of money too.
