Geology of the United States A slice of the Earth from the Pacific Ocean through the Pacific Northwest might look something like the adjacent image. Beneath the Cascades, a dense oceanic plate plunges beneath the North American Plate; a process known as subduction. As the oceanic slab sinks deep into the Earth's interior beneath the continental plate, high temperatures and pressures allow water molecules locked in the minerals of solid rock to escape. The water vapor rises into the pliable mantle above the subducting plate, causing some of the mantle to melt. This newly formed magma rises toward the Earth's surface to erupt, forming a
Negadon: The Monster from Mars creature. His mission accomplished, Narasaki allows himself and "Miroku" to die when Negadon explodes. Negadon: The Monster from Mars In the year 2025, Earth sends an expedition to Mars in the spaceship "Izanami". A huge rock formation is discovered beneath the surface, and is transported back to earth. On the way back, the rock's temperature soars, causing the "Izanami" to explode and crash-land in Tokyo, leaving a large crater. The rock hatches into a colossal alien life form, which proceeds to attack Japan with bolts of energy from its many appendages and orifices. Missiles, tanks, and aircraft all attack but
