Eruption with low silica tends to be nonexplosive. The type of lava is Basaltic, flows easily because of low viscosity (low gas content- originates in the mantle). This type of lava comes from shield volcanoes (low angle slopes and gentle)- eg. Manua Loa Volcano and Hawaii.
Answer:
Precession
Explanation:
Various stars will act as northern stars due to precession, as well as the stars and planets arrayed around the celestial equator (zodiac) will steadily change locations. Every 73 years, they move around one degree. For the remainder of our days, and for a few millennia later, Polaris would stay the North Star.
Is that all the question, and is there any answer choices?
B) Use public transportation often
The appropriate answer is B. DIVERGENT. Divergent margins occur where two oceanic plates are pulling apart or it can occur where a Continental landmass is pulling apart.
As oceanic plates pull apart magma up wells from the mantle and new crust is formed along what is called a spreading ridge. The Mid Alantic ridge is an example of a spreading ridge where new oceanic crust is being formed.
