Latitude is the angular distance of a place north or south of the earth's equator, or of a celestial object north or south of the celestial equator, usually expressed in degrees and minutes. (left to right)
longitude is the angular distance of a place east or west of the meridian at Greenwich, England, or west of the standard meridian of a celestial object, usually expressed in degrees and minutes.(up and down)
Explanation:
Answer: B. Confining pressure decreases on a rising magma, allowing gas bubbles to expand and fracture the magma. This process further decreases pressure on the magma and will result in an explosive event.
Explanation: The bubbles inside the magma are responsible for making it bubble to the surface of the earth crust and the explosion that follows. As magma rises to the surface of the earth, it absorbs gases and water vapor which forms bubbles in the magma. As the pressure decreases in the magma, it causes these bubbles to increase. When the rise of magma cannot keep up with he growth in the bubbles, there is an explosive eruption to the surface. Compare this to shaking a Coca Cola bottle before opening it.
If the magma rise keeps us with the gas bubbles, the eruption is not explosive.
Convection currents in the mantle still had not been discovered at the time.
