The Hawaiian Islands are formed on a region of intra plate volcanic activity on the Pacific plate. This region is known as a hot spot. Scientists are not exactly sure what causes this but they do know that a plume of magma rises through the mantle and forces it's way through the crust to form submarine volcanoes and over time volcanic islands.
The magma that rises here originates from the mantle and not crustal melt and so forms basic or basaltic lava.
The magma chamber below the Yellowstone caldera. It's located in Yellowstone national park.
Answer:
Explanation:
1. glacial tills and cirques Till is derived from the erosion and entrainment of material by the moving ice of a glacier. It is deposited some distance down-ice to form terminal, lateral, medial, and ground moraine. Cirques form by the accumulation of snow and ice avalanching from upslope areas. The size of cirque glaciers ranges from glaciers that are completely limited within hosting bedrock hollows, to glaciers that form the heads of large valley glaciers.
2. ENERGY FROM THE SUN heats up the air at the equator most because of the curvature of the earth. This tends to rise up then head toward the poles where it cools and moves closer to the surface and then more or less back toward the equator.
THE ROTATION OF THE EARTH makes the movement of air relative to the surface of the earth seem to deflect. This Coriolis effect doesn't affect your toilet flushing, but does influence large scale wind patterns and hurricanes.
THE LATITUDE OF VANCOUVER roughly half way between the equator and the north pole positions us so the large scale wind patterns tend to bring us winds from the west.
THE PACIFIC OCEAN sits to the west. Winds pick up moisture from it toward shore. Large bodies of water also tend to hang on to energy that keeps our temperatures more moderate.
THE COAST MOUNTAINS push the moist air upward so it cools off and can't hold on to as much moisture, so it rains.
THE TILT OF THE EARTH'S AXIS relative to the plane of our orbit around the sun means we are tilted away from the sun during winter, so it's cooler. This results in a greater temperature gradient between the equator and the north pole, and the winds get stronger. The cooler temperatures combined with more moisture-ladened wind brings more rain during winter.

Wait what, that’s not really a question
