The ClueFinders 5th Grade Adventures: Secret of the Living Volcano is a computer game in The Learning Company's ClueFinders series of educational software.In the game, the ClueFinders are shipwrecked on a mysterious volcanic island, inhabited by centuries of trapped castaways, where any escape attempt seems to be deliberately thwarted by natural forces.
Volcanology advances have required more than just structured observation, and the science relies upon the understanding and integration of knowledge in many fields including geology, tectonics, physics, chemistry and mathematics, with many advances only being able to occur after the advance had occurred in another field of science. For example ...
They occur wherever lava is extruded underwater, such as along marine hotspot volcano chains and the constructive plate boundaries of mid-ocean ridges. As new oceanic crust is formed, thick sequences of pillow lavas are erupted at the spreading center fed by dykes from the underlying magma chamber.
Pyroclastic shield – Shield volcano formed mostly of pyroclastic and highly explosive eruptions; Resurgent dome – Volcanic landform; Seamount – Mountain rising from the ocean seafloor that does not reach to the water's surface; Shield volcano – Low-profile volcano usually formed almost entirely of fluid lava flows
Volcanic rocks (often shortened to volcanics in scientific contexts) are rocks formed from lava erupted from a volcano. Like all rock types, the concept of volcanic rock is artificial, and in nature volcanic rocks grade into hypabyssal and metamorphic rocks and constitute an important element of some sediments and sedimentary rocks. For these ...
Specifically in sedimentology, a bed can be defined in one of two major ways. [2] First, Campbell [3] and Reineck and Singh [4] use the term bed to refer to a thickness-independent layer comprising a coherent layer of sedimentary rock, sediment, or pyroclastic material bounded above and below by surfaces known as bedding planes.
A kīpuka surrounded by lava flows at Kīlauea volcano, Hawai`i Green kīpukas surrounded by brown lava flows erupted from Iwate volcano, Japan. A kīpuka is an area of land surrounded by one or more younger lava flows. A kīpuka forms when lava flows on either side of a hill, ridge, or older lava dome as it moves downslope or spreads from its ...
On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth's plate boundaries are underwater, most volcanoes are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has ...
