metamorphic rocks

Image
 Metamorphic rocks are one of the three main types of rocks, and they form through the alteration of pre-existing rocks (igneous, sedimentary, or other metamorphic rocks) under the influence of heat, pressure, and chemically active fluids deep within the Earth's crust. The term "metamorphism" comes from Greek words meaning "change in form." Here's a more detailed explanation of metamorphic rocks: **Formation Process:** Metamorphic rocks form from pre-existing rocks (protoliths) that undergo changes in mineral composition, texture, and/or structure due to intense heat and pressure within the Earth's crust. These changes occur without melting the rock entirely. The factors responsible for metamorphism include: 1. **Heat:** Heat from magma, geothermal gradient, or nearby igneous intrusions causes recrystallization of minerals. 2. **Pressure:** Pressure from overlying rock layers or tectonic forces causes minerals to align in specific orientations and can al...

waa maxay folkaano ( whats volcano )

Image
  A volcano is a geological formation characterized by an opening, or vent, in the Earth's crust through which molten rock, ash, and gases escape from beneath the Earth's surface. Volcanoes can be found all over the world, both on land and under the ocean. They are primarily associated with tectonic plate boundaries, where the Earth's crust is either spreading apart, colliding, or sliding past each other. https://www.facebook.com/cifkaguhad/posts/pfbid0zFQhG42JVpLbttKHAKVHxLbuu8cPd9DmkkYtz42pWTvBodifSx3htzBW7c27sUmVl Types of Volcanoes: 1. **Shield Volcanoes**: These volcanoes have gentle slopes and are formed by the eruption of low-viscosity lava, which flows easily and travels far from the vent. Shield volcanoes are characterized by their broad, flattened profiles. Examples include Mauna Loa and Mauna Kea in Hawaii. 2. **Stratovolcanoes (Composite Volcanoes)**: Stratovolcanoes are characterized by steep slopes and are built up by alternating layers of lava flows, ash, and...

waa maxay cilmiga dhulka (GEOLOGY ) ?

this is a link Geology waa daraasad cilmiyeed ee Dhulka, agabkiisa, habraaciisa, iyo qaab dhismeedkiisa. Waxay naga caawinaysaa inaan fahanno taariikhda meereheena, oo ay ku jiraan sida uu u sameysmay, sida uu korkiisa isu beddelay waqti ka dib, iyo sida kheyraadka dabiiciga ah loogu qaybiyo gudaha. Geology sidoo kale waxay door muhiim ah ka ciyaartaa fahamka khataraha dabiiciga ah sida dhulgariirrada, qaraxyada foolkaanaha, dhul goynta, iyo fatahaadaha.   Halkan waxaa ah kala-goynta qaybaha ugu muhiimsan ee geology :   Physical Geology : Laantani waxay diiradda saartaa agabka, hababka, iyo qaab dhismeedka dhulka dushiisa. Waxay sahamisaa mowduucyo ay ka mid yihiin cilmi-baarista macdanta (barashada macdanta), petroloji (barashada dhagaxyada), sedimentology (daraasadda sediments), iyo geomorphology (daraasadda qaab-dhismeedka dhulka).   Juquraafiga Taariikhiga ah ( historical geology) : Juquraafiga taariikhiga ahi waxa uu baadhaa dhulka waagii hore, oo ay ku j...
