The correct answer is option A) Basaltic lava is thicker than andesitic lava.
Basaltic lava is often more fluid than andesitic lava, allowing it to flow more freely. Plagioclase and pyroxene minerals make up the majority of the minerals in basalt, an igneous rock that is black and fine-grained.
The majority of the time, it is created when the Earth's mantle partially melts. Andesite lacks basalt's iron and magnesium content. Extrusive igneous rock known as andesite may be found in both the continental and oceanic crust.
Plagioclase feldspar and pyroxene make up the majority of its composition, along with trace amounts of olivine and biotite.
Andesite has a greater viscosity and is less prone to flow because it contains more silica than basalt. Depending on the kind of magma that is erupted, cinder cones can be made from either andesitic or basaltic magma.

what theor in seismic explains activity of earth ?
The theory in seismology that explains the activity of the Earth is the theory of plate tectonics.
This theory describes the movement of the Earth's lithosphere, which is the outermost layer of the Earth, comprising the crust and the upper part of the mantle. The lithosphere is divided into several large plates, and the theory of plate tectonics describes how these plates move and interact with each other.
According to the theory of plate tectonics, the movement of the Earth's plates is driven by convection currents in the mantle. These convection currents are caused by the heat generated by the decay of radioactive elements in the Earth's core. As the mantle convects, it drags the overlying lithospheric plates along with it, causing them to move and interact with each other.
Earthquakes are one of the most notable effects of plate tectonics, and they occur when two plates move past each other or when one plate is pushed under another plate. The sudden release of energy causes the ground to shake, and this shaking is what we feel as an earthquake.
In summary, the theory of plate tectonics is a comprehensive model that explains the activity of the Earth, including earthquakes, volcanoes, and mountain building. It is based on the movement and interaction of the Earth's lithospheric plates, which are driven by convection currents in the mantle.

Become wider at the base and narrower at the top. Be inverted. Become more rectangular.subduction zones occur a what type of plate boundary?
Converging plate boundaries occur at subduction sones. While some plates collide and build mountains by stacking rocks to release pressure.
Subduction occurs at some convergent plate boundaries. Subduction forces one of the tectonic plates down into the Earth's mantle. This most commonly occurs when one of the plates at the convergent boundary is an oceanic plate and the other is a continental plate the plate,the denser of the two,is pushed down where it melts as it approaches the mantle. Magma produced through plate melting often rises and can reach the surface through the formation of volcanoes.Basaltic oceanic crust contains hydrated minerals such as amphiboles,some of which formed by hydrothermal alteration as seawater seeped through hot, fractured, young oceanic crust on the mid-oceanic ridge.As the oceanic crust sinks further into the mantle,the pressure increases,the temperature of the oceanic crustal rocks rises more slowly because the rocks are poor conductors of heat.At depths of about 100 km below the surface,the pressure is great enough for hydrated minerals to undergo metamorphism.

Look at Model 1. If Rock B was formed in the Silurian Period, and Rock C was formed in the Permian Period, what type of boundary lies between B and C? Explain how this could have formed
Geologically speaking, the Silurian Period is the third stage of the Paleozoic Era. It covered the time between the end of the Ordovician Period and the start of the Devonian Period, starting 443.8 million years ago and ending 419.2 million years ago.
Continental altitudes were often much lower than they are today, and the sea level was significantly higher during the Silurian period. As the massive glaciers from the Late Ordovician ice period melted, sea level rose sharply. As a result of these rising temperatures, numerous faunal taxa were able to recover from the extinctions that occurred in the Late Ordovician. Shallow waters swamped vast areas of numerous continents, and coral reefs that resembled mounds were fairly frequent.

the process in which a denser plate is pushed beneath a less dense plate
The process in which a denser plate is pushed beneath a less dense plate is called subduction.
Subduction occurs at convergent plate boundaries, where two plates are moving towards each other. When a denser oceanic plate collides with a less dense continental plate, the oceanic plate is forced beneath the continental plate and into the Earth's mantle. As the oceanic plate descends, it heats up and begins to melt, creating magma that rises to the Earth's surface, forming volcanoes.
Subduction is a fundamental process in plate tectonics and is responsible for many of the world's largest earthquakes and volcanic eruptions. It is also responsible for the formation of mountain ranges, such as the Andes in South America and the Cascades in North America. The subduction process also plays a crucial role in the Earth's carbon cycle, as the subducted material is eventually returned to the surface through volcanic activity, releasing carbon dioxide into the atmosphere and ocean. Overall, subduction is a complex and dynamic process that plays a vital role in shaping the Earth's surface and influencing its climate and geology.

on what scale is the explosivity of a volcano measured?
The explosivity of a volcano is measured on the Volcanic Explosivity Index (VEI) scale.
Explosivity of a volcano is measured on the Volcanic Explosivity Index (VEI) scale. The VEI scale was developed in the 1980s as a way to categorize and compare volcanic eruptions based on the amount of volcanic material they release into the atmosphere, the height of the eruption column, and the duration of the eruption. The Volcanic Explosivity Index (VEI) scale ranges from 0 to 8, with 0 being a non-explosive or effusive eruption, and 8 being a rare, extremely large, and catastrophic eruption. The VEI scale is logarithmic, which means that each increase of one on the scale represents a tenfold increase in the volume of erupted material.
Volcanoes with a high Volcanic Explosivity Index (VEI) are considered to be "large" or "major" eruptions and can have significant impacts on global climate, air travel, and local communities. These high VEI eruptions can lead to widespread destruction, ashfall, and loss of life. Examples of volcano with high VEI values include Mount St. Helens (VEI 5), Krakatoa (VEI 6), and Tambora (VEI 7). The VEI scale provides a useful tool for volcanologists to compare and understand the magnitude and impact of different volcanic eruptions.

Calculate the most probable speed of an ozone molecule in the stratosphere, where the temperature is 270 k.
Answer:
Explanation:
The most probable speed of a molecule in a gas can be calculated using the Maxwell-Boltzmann distribution. The formula for the most probable speed is given by:
v_mp = (2kT/m)^(1/2)
Where v_mp is the most probable speed, k is the Boltzmann constant (1.38 x 10^-23 J/K), T is the temperature (270 K), and m is the mass of the ozone molecule (48 g/mol, or 48 x 10^-3 kg).
v_mp = (2 * 1.38 x 10^-23 * 270 / 48 x 10^-3)^(1/2)
v_mp = (2.68 x 10^-21 * 270 / 48 x 10^-3)^(1/2)
v_mp = (6.71 x 10^-20 / 48 x 10^-3)^(1/2)
v_mp = (6.71 x 10^-17)^(1/2)
v_mp = 2.59 x 10^-8 m/s
So the most probable speed of an ozone molecule in the stratosphere, where the temperature is 270 K, is approximately 2.59 x 10^-8 m/s.
