Volcanoes play an important role in creating land since they are the sources of magma, which once above ground normally cools to create new land. In the ocean, this land normally forms at divergent and convergent boundaries or hot spots. At divergent boundaries (where two plates move apart), magma constantly erupts along a trench deep below the ocean's surface. This magma rarely piles upward and instead is pushed to both sides of the trench. This is how new seafloor forms. Convergent boundaries can create island arcs like Indonesia as magma erupts bit by bit. Hot spots occur in the middle of plates. They are instances where the mantle pierces through the crust and begins to erupt directly onto to seafloor. Over time, these eruptions will pile up and create underwater volcanoes until they potentially make it above sea level, thereby forming an island. This is how Hawaii was and continues to be formed.
Answer:
The star is a member of an eclipsing binary star system
Explanation:
- A careful explanation about the measurement reveals that the star maintains a steady and apparent shape of brightness and at most of the time remains brighter.
- With and usual intervals of about the 73 hours and then the star becomes contestant dimmer for about every toe hours and is due to the fact that the star is a member of the eclipsing system.
Answer:
An energy system is a system primarily designed to supply energy-services to end-users.[1]:941 Taking a structural viewpoint, the IPCC Fifth Assessment Report defines an energy system as "all components related to the production, conversion, delivery, and use of energy".[2]:1261 The field of energy economics includes energy markets and treats an energy system as the technical and economic systems that satisfy consumer demand for energy in the forms of heat, fuels, and electricity.[1]:941
Answer:
Geologists classify Wave Rock as a flared slope, a concave bedrock surface at the base of the inselberg. Its odd shape comes from two main processes: weathering and erosion. Chemical weathering of the softer rock at the base by groundwater did most of the work, while erosion from wind and rain added further touches.
