A theodolite works by combining optical plummets (or plumb bobs), a spirit and graduated circles to find vertical and horizontal angles in surveying. An optical plummet ensures the theodolite is place as close to exactly vertical above the survey point.
hope it helps XD
Answer:
The economic effects were more significant than the social effects.
Explanation:
The social effects included the flooding of over 600 houses and the evacuation of 16 farms. Villages, such as Borrowbridge, were cut off, and power supplies, roads, and railways were also affected. The Bristol to Taunton line was closed at Bridgwater for instance. The environmental impacts were even worse though; an enormous volume of debris dumped by the floodwaters had to be cleaned up and stagnant waters had to be re-oxygenated before being pumped back into rivers. However, I think the worse impact of all was the contamination of all flooded areas by oil, agricultural chemicals, livestock effluent, and human sewage. I think that this is the worst impact because of its potential for causing harm to humans and other animals.
In conclusion, I think that the socio-economic and environmental effects of this flood were both important but that the environmental effect was more important, because of the potential to cause harm.
Answer:
1. They usually host three or more ecosystems where animals can’t live.
4. They usually host one ecosystem with a variety of plants
Explanation:
A mountain ecosystem has more than one ecosystem. This is mainly due to the diversity of climate that this environment promotes. Due to its proximity to the ocean, slope and elevation, the mountain ecosystem promotes different areas that create different ecosystems, some more humid and others drier.
In this environment there is usually a wide variety of plants, but not animals.
When the price of oil drops this usually means that OPEC or a major state within OPEC like Saudi Arabia, or Venezuela has increased the supply of oil leading to a drop in price. This is the current policy of the Saudi Government which has led to a drastic decline in oil prices over the last 3 to 4 months.
