known as the mantle. Earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core

Answer:
Hard engineering strategies - advantages and disadvantages
Erosion is a natural process which shapes cliffs. Over time, erosion can cause cliff collapse - therefore the coastline needs to be managed. Hard engineering involves building artificial structures which try to control natural processes. Each engineering strategy has its advantages and disadvantages.
Sea walls

A sea wall
Concrete walls that are placed at the foot of a cliff to prevent erosion. They are curved to reflect the energy back into the sea.
Advantages
Effective at protecting the base of the cliff.
Sea walls usually have promenades so people can walk along them.
Disadvantages
Waves are still powerful and can break down and erode the sea wall.
Expensive - approximately £2,000 per metre.
Answer:
The pyroclastic surge would take 1.609 minutes to reach the site of ancient Pompeii.
Explanation:
The ruins of Pompeii are about 5 miles away from Mount Vesuvius. A mile equals to 1.609 kilometers. If pyroclastic surge travels in a straight line at constant speed, then the time (
), in minutes, taken to reach the site of the ancient Pompeii can be determined by the following kinematic equation:
(1)
Where:
- Travelled distance, in kilometers.
- Speed of pyroclastic surge, in kilometers per hour.
If we know that 
and 
, then the time needed to reach the site of ancient Pompeii is:
The pyroclastic surge would take 1.609 minutes to reach the site of ancient Pompeii.
Two dominant climates in South Asia are:
- Tropical wet or equatorial climate
- Tropical dry or Savannah climate
<u>Explanation:</u>
Tropical wet climate characteristics :
- There are heavy rainfall and no dry season. The climate is consistent throughout the year.
- The regions in South Asia where this climate prevails are the west coast of India up to Mumbai, South of Sri Lanka, and the south of Bangladesh.
- The type of ecosystems found in the Tropical wet climate region is the Evergreen tropical rain forest and Monsoon rain forest.
- Animal found here is the monkey and vegetation available here are teak and ebony
Tropical dry climate characteristics :
- This climate is mainly characterized by a dry season followed by a wet season. It is found mainly in Southern India, Southern Bangladesh, and Sri Lanka.
- The tropical monsoon season is from July to December. The landscape in these regions is midway between a rain forest and a desert, mainly composed of grasslands.
- The type of ecosystems found in these regions is deserts and grasslands. Animal found here commonly is the elephant and vegetation found prominently are orchids and cacti.
