Answer:
Basaltic (mafic) magmas are hotter and have higher viscosity than felsic magmas
Explanation:
- The most accurate statement related to the viscosity of magma is the amount of silica content in this as more the vicious magma will be more is the content of deadly gases and thus more rapid and dangerous will be the explosion of lavas with gas.
- The higher the amount of gas and the high level of felsic lava produced has a higher velocity and explosive rate thus is more silicic which is a result of the chemistry, which is high in aluminum, potassium, sodium, and calcium contents forming a liquid rich lava and temperature can go high as 650 to 750 degrees.
- As compared to the mafic lava have a higher concentration of ferromagnesian which can generally erupt at a temperature of more than 950 degrees. Thus flow at higher speeds and for longer distances.
Population growth is the increase in the number of individuals in a population.
There's lots of resources that the Amazon rainforest provides to the people around the world, of which the most important ones are:
- Fresh water; it contains around 20% of the world's fresh water.
- Oxygen; it is the biggest producer of oxygen on the planet.
- Food; healthy food distributed all over the world.
- Medicinal plants; thousands of plants that can cure and prevent most of the known diseases.
- Minerals; gold, copper, silver, zinc, tin...
Answer:
Storm surges, rising sea level, development along coastal areas.
Explanation:
A storm surge, which is also known as a storm flood, tidal surge, or a storm tide, is like a coastal flood, with rising water that is commonly associated with a few types of low pressure weather systems. During a storm surge, strong winds are produced which push water to the shore, causing flooding. These are a cause of coastal erosion because the high storm surges can shift the erosive force of a wave higher onto the beach. Rising sea level basically means there is an increase in the oceans, commonly caused by global warming. The Rising sea levels cause coastal erosion due to the ocean eroding the sand from the beaches. Development along coastal areas is a cause because as the sea level rises, waves at the higher elevation levels will increase coastal erosion.
