Answer:
Chemical weathering is different from mechanical weathering because the rock changes, not just in size of pieces, but in composition. ... Chemical weathering works through chemical reactions that cause changes in the minerals.
Answer:
That depends on the basic principles of the sun rising every day and generating some degree of heat. When the sun sets, that heat source disappears. That concept is easy to understand because you can see the process.

Answer:
C) rebellions in Ireland between 1916 and 1921
Explanation:
The religious conflict in Northern Ireland has been building on for some time, but it escalated in the early 20th century when multiple rebellions broke up. The main reason for the religious conflict was that part of the population was Catholic, while part was Protestant. This was used not just in religious manner, but also as a nationalistic one, as Northern Ireland was not very fond of being part of the British Empire. Once the conflict started it continued for quite some time, until the 1990's, and lot of terrorist attacks took place, as well as assassinations, clashes between the two groups and lot of deaths of innocent civilians.
Answer:
True
Explanation:
The primary reason magma forms at subduction zones is that the subducting plate carries a cover of sediments, water, and hydrated minerals down with it, which lowers the temperature required for the adjacent overlying mantle lithospheric rock to melt.True
Subduction is a geological process that takes place at convergent boundaries of tectonic plates,this zones are the second most important environment on Earth for volcanic eruptions
Magma is produced in the subduction zone as a result of the subducting plate carrying a cover of sediments, water, and hydrated minerals down with it, which lowers the temperature required for the adjacent overlying mantle lithospheric rock to melt. Due to the heat caused by it rubbing against the other plate as well as the natural heat of the mantle in the earth crust, the plate melts and turns into magma, also the melting of peridotite in the presence of water results in the generation of magma,this addition of fluids lowers the melting point of the mantle.
magmas in subduction zone volcanoes are often explosive, because they arrive at the surface as very sticky and gas rich
