Answer:
Convection currents in the Earth's core are caused by hot magma rising upwards, cooling, then sinking back toward the core. These convection currents are the driving force for tectonic plate movement in the crust. The constantly moving magma in the mantle carries the plates sitting on top of it. The hotter the magma, the faster the speed of its convection currents.
If the interior of the Earth were to cooler, then the movement of the plates would decrease.

The correct answer is - d. shield volcanoes.
The Hawaiian volcanoes are volcanoes that fall into the category of the shield volcanoes. They are slightly dome shaped volcanoes, spread out over a very large area, are not steep, and are volcanoes that tend to not have explosive eruptions as their magma is usually high in silica content.
The volcanoes on Hawaii are volcanoes that have formed over a hot spot, which means that they are not formed at the boundary of the tectonic plates, but instead, they are formed in the middle of the plate.
Mauna Loa and Mauna Kea are actually the biggest volcanoes in the world in the present day.
Over half of India's population works in agriculture, and monsoon rains directly affect their incomes and livelihood. Agriculture adds up to more than 15% of India's Gross Domestic Product (GDP), which means that when crops fail because of too little rain, the economy suffers.
Although global human impact (global warming) is not to be ignored, this is mainly because of the El Nino in the <span>central and eastern equatorial Pacific Ocean.
If you're in the Eastern USA, its messing with the jet stream the high/low pressure ridges, causing the cold front to not be within the Northeastern USA area this year.
If you're in other areas far enough I don't know, global warming?
