A basalt would form under conditions that included. View Test Prep - Geology_exam_1_review from GLY 1010 at Broward College. A sedimentary rock formed by the deposition of successive layers of clay.

Basalt melts at ca. The blueschist facies form under which of these conditions. None of the above.

Unconsolidated sediment typically has greater porosity than the lithified rock it will eventually form. Basalt is a type of igneous rock that is typically dark in coloration with a fine-grained texture. Basalt that erupts under open air that is subaerially forms three distinct types of lava or volcanic deposits.

Which of these are forms of mass media. It is the most common type of rock in the Earths crust and it makes up most of the ocean floor. The intrusion of a narrow sill or igneous dike below the crust also results in the formation of basalt.

C a mafic magma cooling on Earths surface. Large basalt deposits near the equator B. Metamorphic rocks formed under the lowest metamorphic temperatures and pressures 250 o C and Basalt metamorphosed.

B a felsic magma cooling in the subsurface. Under room temperature basalt stone breaks before gaining plastic properties. Abasalt forms under which of the following conditions.

Which of the following statements best describes the difference between Swedens population policies and those pursued by India. A change in the texture structure or chemical composition of a rock due to contact with magma. Ash or cinder.

E none of the above. A basalt would form under conditions that included A. The many uses of Basalt include the following.

Basalt is primarily formed by the extrusion of lava flows onto the surface of the earth during a volcanic eruption. The cooling appears to be very quick because the lava is exposed to a much lower temperature that its own temperature thus starting to cool of loses its liquidityviscosity and becomes solid. Types of Basalt Basalt types.

Textile applications for fire protection. In contrast the basalt fibers exhibit flexible properties to a certain degree. Intrusive igneous rocks are usually coarse grained due to the slow process of.

On the other hand basalt flows block the main stream channel resulting in a surface depression in which sedimentation of silt clay or volcanic ash provides an impervious layer. If a basalt body cuts across a fault what are the relative ages of the basalt and the fault. Basalt is an example of extrusive igneous rocks.

Identify which metamorphic process is shown in the following image. A silicic magma cooling deep underground. Tholeiites vs alkali basalts.

A silicic lava cooling at earths surface. Basalt is an igneous rock that contains more than 45 and less than 52 of SiO2 and less than five percent of total alkalies K2O Na2O3. Included in this category.

A basalt forms under which of the following conditions. Basalt in the tops of subaerial lava flows and cinder cones will often be highly vesiculated imparting a lightweight frothy texture to the rock. Metamorphic facies encompass different regions in P-T space and are named on the basis of certain characteristic minerals that form through metamorphism of primarily basalt.

It is made of many dark colored minerals such as pyroxene and olivine. Aa basalt forms when lava has high viscosity flows poorly like honey or flow is turbulent. Metamorphism that occurs as a consequence of shearing alone with no change in temperature or pressure.

Compared with low-grade metamorphic rocks high-grade rocks. D a felsic magma cooling on Earths surface. As of the 2000s around _______ percent of Indians were considered illiterate.

Tholeiitic basalt is relatively rich in silica and poor in sodium. Basalt is an igneous rock formed from the lava flows that cool off pretty quickly either on the surface or very close to the surface. Consult the figure below.

A a mafic magma cooling in the subsurface. Mehr Kashmiri GLY1010 Exam 1 Test review Questions for lecture class. Large basalt deposits near the poles D.

An intermediate lava cooling at earths surface. Goldenfox 79 I would say the answer would be D. Basalt has a strict chemical definition.

Basalt also contains some light colored minerals such as feldspar and quartz but the amounts are small. Basalt stones in their original form are not flexible or elastic. A felsic magma cooling on Earths surface.

Pillow basalt forms when lava erupts under water and cools almost instantly. A mafic lava cooling at earths surface. Igneous rocks can be extrusive or intrusive base on the formative environment.

It is defined in the TAS diagram shown above. Under which of these conditions would a body of rock be more likely to exhibit plastic behavior. 2 on a question.

When this magma solidified in the interior part of the earth it forms intrusive igneous rocks. Basalt products resist the open flame. When coming to heat resistance Basalt is exceptionally suited to block fire.

A mafic magma cooling deep underground. High pressure but relatively low temperature. A felsic magma cooling in the subsurface.

Basalt is an extrusive igneous rock that is very dark in color. Generally igneous rocks are formed from molten magma. Under which of the following conditions would the effect of silicate weathering be greatest.

Basalt does not melt nor shrink in the flame and when not mechanically stressed keeps its geometric integrity. Large rhyolite deposits near the equator.
