An earthquake and a volcanic eruption on Grenada will have devastating effects.
Explanation:
The Caribbean countries (in this case we'll speak about Grenada) that have active volcanoes tend to be small islands. This makes them ultra vulnerable if a natural disaster or combination of multiple natural disasters strikes. The reason as to why they are in such bad position if this occurs is because everything will be stranded on a very small area, with the full effect of the disaster being felt, no one will be able to get to a safe place, and it is hard for help to come from other countries.
A stronger volcanic eruption combined with an earthquake has the capability of destroying the majority or all of the infrastructure in this country. But it is not that that will be the most tragic, it will be that all of the population will be stranded and in danger to get injured or end up dead which can go so far that the country may even seize to exist.
Answer:
Lower viscosity and low gas content mean higher temperature of magma.
Explanation:
Viscosity of magma, the resistance to flow depends on composition of the magma and temperature. Higher silica content means higher viscosity. But lower temperatures and low gas content mean higher viscosity.
Viscosity is the resistance to flow (opposite of fluidity). Viscosity depends on primarily on the composition of the magma, and temperature. Higher SiO2 (silica) content magmas have higher viscosity than lower SiO2 content magmas (viscosity increases with increasing SiO2 concentration in the magma).
A, Fossils found in the sandstone layers offer dramatic evidence of the climate change in the Tibetan region due to plate movement over the past 100 million years.
The convection drive plates tectonics through a combination of pushing and spreading apart at mid-ocean ridges and pulling and sinking downward at subduction zones. At subduction zones, two tectonic plates meet and one slides beneath the other back into the mantle, the layer underneath the crust.
Answer:
Higher elevations experience cooler temperatures compared to lower elevations.
Explanation:
Elevation helps to determine the temperature of an area through relationship between availability of air and the pressure. The higher the elevation, the lower the availability of air which in turns leads to lower pressure.
This lower pressure influences the temperature of that point to be cooler. At same time, the lower the elevation and all things being equal, the hotter the temperature.
