What are the types of volcano?
GeologyThe Three Classic Types of Volcanoes Cinder Cone Volcanoes. Composite Volcanoes (Stratovolcanoes) Shield Volcanoes. What are the 5 types of volcanic? different types of volcanoes of volcanoes that can be found in nature are such as composite volcanoes, shield volcanoes, cinder cones, spatter cones and complex volcanoes. What are main types of volcanoes? Geologists generally
How is limonite mined?
Geology questionsIt is usually formed from the chemical weathering of iron rich minerals, such as biotite, amphibole, pyroxene, and olivine, the hydration/oxidation of iron rich sulfide minerals, or from the hydration of magnetite and hematite. Limonite is commonly deposited in run-off streams resulting from mining operations. How is limonite formed? Description: Limonite is a general term
What is a terminal moraine made of?
GeologyA terminal, or end, moraine consists of a ridgelike accumulation of glacial debris pushed forward by the leading glacial snout and dumped at the outermost edge of any given ice advance. It curves convexly down the valley and may extend up the sides as lateral moraines. How are terminal moraine created? Terminal moraines form when
What is form of a mineral?
GeologyThe four main categories of mineral formation are: (1) igneous, or magmatic, in which minerals crystallize from a melt, (2) sedimentary, in which minerals are the result of sedimentation, a process whose raw materials are particles from other rocks that have undergone weathering or erosion, (3) metamorphic, in which … What are 3 ways minerals
Why do plants grow well in volcanic soil?
GeologyThese minerals include sulfur, potassium, and phosphates, which plants often have a hard time getting. When combined with heavy rainfall, volcanic soil becomes very fertile, or good for growing plants. Is volcanic soil good for plants? By adding volcanic rock dust back to the soil, it makes it accessible to plant roots as soon as
Why is the moon no longer geologically active?
GeologyThe moon is no longer geologically active because: it is small so has lost most of its internal heat. Is the Moon still geologically active? In 2012, new observations showed surface features, called graben, which form where the crust has pulled apart; these features are evidence that the Moon is expanding in some places. These
How do we know earth’s outer core is liquid?
GeologyBy tracking seismic waves, scientists have learned what makes up the planet’s interior. P-waves slow down at the mantle core boundary, so we know the outer core is less rigid than the mantle. S-waves disappear at the mantle core boundary, so the outer core is liquid. How do we know that Earth’s core is liquid?
What is the difference between constructive and destructive plate boundary?
GeologyThey are called constructive plates because when they move apart, magma rises up in the gap- this forms volcanoes and eventually new crust. One example is the Mid-Atlantic Ridge, where the gap can be found in Thingvellir, Iceland. Destructive plate boundaries are when oceanic and continental plates move together. What is the difference between a
What types of organisms lived during the Archean eon?
GeologyLife in the Archean was limited to simple single-celled organisms (lacking nuclei), called prokaryotes. In addition to the domain Bacteria, microfossils of the domain Archaea have also been identified. What type of organism was most common during the Archean eon? These organisms were prokaryotes, a group of unicellular organisms with rudimentary internal organization that began
What type of boundary exists between the Philippine plate and the Pacific plate?
Geologyconvergentconvergent. The Pacific plate is subducting beneath the Philippine Sea plate to the east while the west/northwestern part of the Philippine Sea plate is subducting beneath the continental Eurasian plate. Which plate boundary is formed between the Philippine plate and the Pacific Plate? It is separated from the Philippine Sea Plate to the west by
