waa maxay cilmiga dhulka (GEOLOGY ) ?

Image
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...

metamorphic rocks

 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...

plate tectonics

 Plate tectonics is a scientific theory that describes the movement and interaction of large pieces of the Earth's lithosphere, known as tectonic plates. These plates are like giant puzzle pieces that fit together to form the Earth's outer shell. Plate tectonics explains many geological phenomena, including earthquakes, volcanic eruptions, mountain building, and the distribution of continents and ocean basins. Here's a comprehensive explanation of plate tectonics: **1. Lithospheric Plates:** The Earth's lithosphere is divided into several large and small tectonic plates, which float on the semi-fluid asthenosphere beneath them. These plates are composed of both the crust and the uppermost part of the mantle. The boundaries between plates are regions of intense geological activity. **2. Types of Plate Boundaries:** There are three primary types of plate boundaries, each associated with distinct geological processes: - **Divergent Boundaries:** At divergent boundaries, t...
