What is considered a Ferromagnesian silicate?
Regional SpecificsFerromagnesian silicates contain iron (Fe) or Magnesium (Mg). These elements produce dark mineral colors. The ferromagnesian minerals tend to look metallic in their luster, have relatively high density, and are often magnetic. Non-silicate minerals include a wide variety of minerals. What mineral is a Ferromagnesian silicate? Biotite mica can have iron and/or magnesium in it
How do you get to Siccar point?

What are two ways volcanoes can form near convergent boundaries?
Regional SpecificsAs the sinking plate moves deeper into the mantle, fluids are released from the rock causing the overlying mantle to partially melt. The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary. What are two ways volcanoes can form? Divergent boundaries (crust moves
Where can you find scoria?
Regional SpecificsScoria is common in areas of recent volcanism, such as the Canary Islands and the Italian volcanoes. It is relatively low density due to its vesicles, bu it is not as light as pumice. Also differs from pumice in that it has larger vesicles with thicker walls. Where does scoria come from? Scoria forms when
How does a sedimentary rock become stratified?
Regional SpecificsStratification in sedimentary rocks may result from changes in texture or composition during deposition; it also may result from pauses in deposition that allow the older deposits to undergo changes before additional sediments cover them. How does a sedimentary rock become stratified Brainly? Answer Expert Verified Stratified rocks are nothing but sedimentary rocks. Strata means
What are the three horizontal zones of the ocean?
Regional SpecificsThe ocean is divided into horizontal zones based on the distance from shore and the depth of water beneath: the intertidal, neritic, and oceanic. What are the horizontal zones? I. Horizontal zones (those extending from land out to sea). The habitats are alternately submerged under salt water and waterlogged for hours and then exposed to
