Where were the bombs dropped in the World War 2?
In almost every country in Europe and Asia. Some were dropped on the USA. There were literally millions of bombs used- it would be impossible to be specific and have a brief list.

The barrel of explosives on time tangled is on the left of the Great Wall of China.
You would have to define what a "Thermal bomb" is, since that is not a standard term used in ordnance. There is a Thermal Bomb in some of the Star Wars stories- sorry- not real.
How much does it cost to make and to remove a landmine?
There are many different varieties of landmines- cost to manufacture may range from around $3-5, up to $50 or more more more complex anti-tank mines. The cost of removal is relatively small, being mainly labor. However, the VERY high cost can be in LOCATING them. To do so safely may require equipment such as mine detectors, ground penetrating radar, etc. Once located, IF possible, they may be destroyed in place by a small explosive charge.
