Questions And Answers On The Subject Of Earthquakes
The explosiveness of a volcanic eruption depends on the pressure of the magma. Gases create that pressure, and if the magma is viscous those gases cannot escape easily. Felsic and intermediate magmas tend to have more gas than mafic magmas, and are also more viscous, trapping the gas in. When magma is deep within the crust the pressure is too high for the gases to bubble out of solution. Pillow lavas form where mafic lava erupts in water.

When the magma oozes out into the water the outside cools first forming a hard skin that maintains the pillow shape. Composite volcanoes can produce rocks with a wide range of textures, including 1 aphanitic or porphyritic rock from lava flows, 2 pyroclastic rock with textures ranging from fine ash to coarse fragments from explosive eruptions, and 3 sedimentary rock from lahars.

A lahar is a mud flow or debris flow on a volcano. Lahars are common on composite volcanoes because they are steeper than shield volcanoes, they typically have ice and snow, and they are not as strong as shield volcanoes. Some lahars form during an eruption when snow and ice melt quickly, while others may form from heavy rain. The magma at shield volcanoes is typically non-viscous.

It can flow easily and also tends to form lava tubes, and thus is able to extend a long way from the vent, forming a low broad shield. Shield volcanoes tend to have much longer lives than composite volcanoes. Most of the Hawaiian shields, for example lasted 1 million years, while most composite volcanoes are younger than , years. Weak seismic activity is associated with all stages of a volcanic eruption. In the early stages magma is moving at depth and pushing rock aside, creating small earthquakes. The flow of magma can also produce special type of seismic response known as harmonic tremor. GPS technology is used to determine if there is any slow deformation of the flanks of a volcano related to movement of magma toward the surface. The Mt. Helens columnar basalts were formed by a flow of mafic lava. The Nazko Cone is thought to be related to a mantle plume. No one is certain why there a lower rate of volcanism in B. It is likely that carbon dioxide released during the eruption flowed downhill from the volcano to the village on the shore of the Nass River.

OpenStax College Physics Solution, Chapter 16, Problem 56 (Problems & Exercises) (4:34)
Chapter 5 Before a rock can be exposed at surface it has to be uplifted from where it formed deep in the crust, and the material on top has to be eroded. Frost wedging is most effective at times when the weather swings between freezing at night and thawing during the day. In cold parts of B. In warmer regions it only happens consistently during the winter. Under conditions of strong chemical weathering, feldspar albite NaAlSi3O8 will be converted to a clay such as kaolinite and sodium ions in solution. Where mechanical weathering is predominant, albite will be broken into small pieces. Acid rock drainage ARD creates acidic stream runoff and also enhances the solubility of a wide range of metals, some of which can be toxic.

Content Practice A Lesson 1 Answer Key Earthquakes
Luvisolic soils are found in central B. The weathering feldspar to clay involves the conversion of atmospheric carbon dioxide to dissolved bicarbonate, which ends up in the ocean. Both silt and clay feel smooth between your fingers, but only clay feels smooth in your mouth. The key factor is particle size not density. Settling velocity is controlled by the friction around the grain holding it up and the gravitational force pushing it down. The gravitational force is proportional to the grain volume and the friction is proportional to the surface area.

Conglomerate cannot be deposited by a slow-flowing river because clasts larger than 2 mm are not transported by slow-moving water. Source area lithology: rock that contains quartz such as granite or sandstone , strong weathering to remove feldspar, long fluvial transportation to round the grains. The carbon within carbonate deposits such as limestone originally comes from the atmosphere. Terrestrial depositional environments: rivers, lakes, deltas, deserts, glaciers. Marine depositional environments: continental shelves, continental slopes, deep ocean. A foreland basin forms in the vicinity of a large range of mountains where the weight of the mountains depresses the crust on either side. A forearc basin lies between a subduction zone and the related volcanic arc. Bedding forms where there is an interruption or change in the depositional process, or a change in the composition of the material being deposited. Cross-bedding forms in fluvial or aeolian environments where sand-sized sediments are being moved and ripples or dunes are present.

Graded bedding Mud cracks form where fine-grained silt or clay sediments are allowed to dry because the level of a lake decreases. Reverse graded bedding forms during gravity flows, such as debris flows. A formation is a series of beds that is distinct from other beds above and below it, and is thick enough to be shown on the geological maps that are widely used within the area in question. The Nanaimo Group was actively mined for coal for many decades. During that time the names were given to members and individual beds that were important to the coal miners.

Chapter 7 Heat and pressure are the main agents of metamorphism. Heat leads to mineralogical changes in the rock. Pressure also influences those mineralogical changes, while directed pressure greater pressure in one direction leads to foliation. At very low, low, medium, and high metamorphic grades, mudrock will be transformed into slate, phyllite, schist, and gneiss. Granite remains largely unchanged at lower metamorphic grades because its minerals are still stable at those lower temperatures. Foliation exists because as new minerals are forming in a situation of directed pressure they are forced to grow with their long axes perpendicular to the main pressure direction. At a spreading ridge the heat from volcanism leads to the development of a groundwater convection system in the oceanic crustal rock.

Heated water rises in the hot regions and is expelled into the ocean, while cold ocean water is drawn into the crust to replace it. The heated water leads to the conversion of ferromagnesian minerals e. The geothermal gradient varies as a function of tectonic setting, being greatest in volcanic regions and lowest along subduction zones. As a result the depth at which specific metamorphic grades is achieved will vary greater depth where the gradient is least. The geothermal gradient is low within subduction zones because the cold subducting oceanic crust takes a long time to heat up , so while pressure increases at the normal rate the temperature does not.

Frequently Asked Questions About Earthquakes (FAQ)
Volcanoes can form at subduction zones where two plates collide, one being driven down into the mantle and the other riding over the top. This causes the lithospheric plate to melt and being less dense than the rock in the mantle it will rise. This rising magma will produce a volcano. Volcanoes can form at a mid-ocean ridge. When the two plates separate magma fills the void and a volcano is produced. These chains of volcanic mountains are the longest mountain chain in the world. Volcanoes can also form at a hot spot. Why do earthquakes ocurr? Earthquakes occur because the Earth's plate are in motion. The plates do not move smoothly and evenly. Great stresses build up along the plate boundaries. When a plate moves suddenly a great amount of energy is released in the form of wave energy. These waves are what cause the damage from an earthquake. Where do most of the world's earthquakes occur? Along plate boundaries. How does a volcano grow larger?
