23.09.2021  Muscles of mastication Masticatory muscles The muscles of mastication are a group of muscles that consist of the temporalis masseter medial pterygoid and lateral pterygoid The temporalis muscle is situated in the temporal fossa the masseter muscle in the cheek area while the medial and lateral pterygoids lie in the infratemporal fossa

Andesite Igneous Rock

Andesite and diorite have a composition that is intermediate between basalt and granite This is because their parent magmas formed from the partial melting of a basaltic oceanic plate This magma may have received a granitic contribution by melting granitic rocks as it ascended or mixed with granitic magma Pavlof Volcanoplate tectonics Simplified plate tectonics cross section showing how

THE WORLD GEOGRAPHY 14 Spectacular Basalt Formations

21.09.2021  Basalt is a common volcanic rock formed from the rapid cooling of basaltic lava exposed at or very near the surface of our planet Jointed basalt columns as the most famous and most beautiful basalt formations exists on many places on earth These unusual columns are predominantly hexagonal in cross section but basalt polygons with three to twelve or more sides can be observed.

Earth Crust Oceanic Crust vs Continental Crust

05.01.2021  When the lava hardens it becomes dark rock basalt and forming new plates Because divergent plates fill in the gaps with basalt the oceanic crust turns out to be very young geologically Over time the plates grow at the oceanic crust and older rock is pushed away from mid oceanic ridges When young rock forms at mid oceanic ridges the older rock beneath the ocean is pushed away This

Mechanics of Materials Bending Normal Stress

The cross section on the right is even easier since the centroid has to line on the axes of symmetry it has to be at the center of the object Now that we know how to locate the centroid we can turn our attention to the second moment of area As you might recall from the previous section on torsion this is defined as And finally sometimes we will need to determine the second moment of

3.5 Intrusive Igneous Bodies Physical Geology

3.5 Intrusive Igneous Bodies In most cases a body of hot magma is less dense than the rock surrounding it so it has a tendency to move very slowly up toward the surface It does so in a few different ways including filling and widening existing cracks melting the surrounding rock called country rock 1 pushing the rock aside where it

Mid Atlantic Ridge

The ocean ridge rises to between 2 to 3 km above the ocean floor and has a rift valley at its crest marking the location at which the two plates are moving apart The Mid Atlantic Ridge like other ocean ridge systems has developed as a consequence of the divergent motion between the Eurasian and North American and African and South American Plates.

4.5 Divergent Plate Boundaries Introduction to Oceanography

4.5 Divergent Plate Boundaries Modified from Physical Geology by Steven Earle in other words it is igneous rock e.g basalt or gabbro rich in ferromagnesian minerals forming from magma derived from partial melting of the mantle caused by decompression as hot mantle rock from depth is moved toward the surface Figure 4.5.3 The triangular zone of partial melting near the ridge


In this section the tensile stress–strain curves and the failure modes of the basalt grid strips are presented and discussed Given the discrete distribution of the yarns along the width of the samples the cross sectional area of the grid was evaluated as the equivalent thickness provided by the manufacturer multiplied by the width calculated as the number of yarn spacings in the strip

Mid ocean ridge

Mid ocean ridge cross section cut away view A mid ocean ridge MOR is a seafloor mountain system formed by plate tectonics It typically has a depth of 2 600 meters 8 500 ft and rises about two kilometers above the deepest portion of an ocean basin This feature is where seafloor spreading takes place along a divergent plate boundary.

Continental Margin

Simply the theory states that the surface of the planet is broken into sections some large some small called tectonic plates As these plates drift slowly over Earth they slide past collide with and move away from each other The boundaries where the plates meet and interact are called plate margins What moves the plates along occurs within the planet.
