True. As the seafloor spreads, the distance between Africa and South America is decreasing.

Seafloor spreading occurs when two plates spread apart due to convection currents in the mantle. This process creates new oceanic crust and pushes existing plates away from each other, resulting in an increase in the size of the oceanic basin. The heat from the mantle creates magma which rises through the oceanic crust and cools when it reaches the surface, forming new oceanic crust.

Seafloor spreading affects Earth's surface by changing the size and shape of the oceans. As plates move apart, new oceanic crust is formed and the ocean basin widens. This can cause changes in the shoreline and can cause earthquakes and volcanoes. Seafloor spreading also affects the formation of mountains and islands, as the plates push against each other. These changes in Earth's surface have a profound effect on global climate, as they can affect wind and water patterns.

Dynamothermal metamorphism occurs when a. rock becomes deeply buried during continental collision and mountain building.

Metamorphic rocks are metamorphic rocks from pre-existing rocks that are manifested by changes in mineral composition, texture, and rock structure (solid fraction) occurring in the solid phase due to changes in temperature, pressure, and chemical conditions within the crust (Ehlers and Bratt, 1982).

Metamorphic rocks are therefore formed by changes caused by metamorphic processes. Metamorphic processes are processes of alteration of rocks due to changes in pressure, temperature, and the presence of liquid/gas chemical activity, or changes in these three factors.

Metamorphic processes are isochemical processes in which chemical elements are not added to metamorphic rocks. It has a temperature range of 2000 C to 8000 C and does not pass through the liquid phase (Dicate of Petrology Practicum, 2006).

The thickest layer of the Earth is the Earth's mantle, which is made up of molten rock.

The mantle is the layer that lies between the crust and the outer core of the planet. It is approximately 2900 km thick and makes up 84% of the Earth's total volume.

The mantle is composed mostly of iron, magnesium, and silicon-based minerals, which are held together by the intense pressure and heat of the Earth's interior. The mantle is also the source of much of the Earth's volcanic activity, as it contains pockets of molten rock that are released as magma through volcanoes.

The mantle also plays a role in the movement of the Earth's tectonic plates, which are constantly shifting and sliding against each other.

The given statement "gps measurements of surface deformation can help us estimate the potential magnitude of the next earthquake to occur on a particular fault" is true.

GPS measurements of surface deformation can help us estimate the potential magnitude of the next earthquake to occur on a particular fault.

By measuring the amount of displacement that has occurred on the fault, scientists can estimate the amount of energy that has built up on the fault, and therefore the potential magnitude of the next earthquake that could occur.

GPS measurements can also be used to determine the location of the fault and the direction of displacement, which can help scientists to better understand the seismic activity of a particular fault and the behavior of earthquakes in the area.

The hornfels facies is a metamorphic realm of high temperature but low pressure (C)

A hornfels is a rock that has been changed by heat. This means that the textures of hornfelses are the result of crystallization, or recrystallization, which happens at high temperatures and low to moderate pressures when there is no directed pressure. The aureole of granitic intrusions in the upper or intermediate crust is the most prevalent location for the formation of hornfels. Minerals that are rare and unique can be produced when hornfels undergo contact metamorphism as a result of volcanic activity that occurs extremely near to the earth's surface.

Answer:

by people ignoring it until the last min

Explanation:

The axes of rotation of the planets not found to align perpendicular to the ecliptic because the apparent location of the Sun takes a year to accomplish a full round of the ecliptic because Earth takes a year to orbit the Sun.

The ecliptic plane is coplanar with Earth's equatorial plane, but they are inclined to one another by an angle of around 23.4° because Earth's rotating axis is not perpendicular to its orbital plane. This angle is referred to as the ecliptic's obliquity. When the equator is pushed outward to the celestial sphere, it crosses the ecliptic at two places known as the equinoxes.

The Sun crosses the celestial equator at these locations in its apparent travel along the ecliptic, one from south to north and the other from north to south. The vernal equinox, also known as the first point of Aries and the ascending node of the ecliptic on the celestial equator, marks the passage from south to north.

Continental crust is the outermost layer of the Earth's crust and is made of low-density, relatively thick and granitic rocks. It is thinnest beneath zones of stretching, called rifts, where the lithosphere is being pulled apart.

Continental crust is denser than oceanic crust, which is composed of high-density, relatively thin and basaltic rocks. Oceanic crust is much thinner than continental crust, and is composed of more mafic rocks than continental crust, which is composed of more felsic rocks.

The top half section of the mantle is called the asthenosphere.

The mantle is important because it is the layer of the Earth located between the crust and the core, and it is believed to be the source of the Earth's heat and magnetism. It is also the layer in which plate tectonics and other geological activity takes place. It contains a significant amount of rock, minerals, and other materials which are essential for the Earth's structure, composition, and evolution.

The asthenosphere is important because it is the layer of the Earth's mantle that is most responsible for plate tectonics. It is a relatively weak layer that is plastic and allows the lithospheric plates to move and interact. It is also important because it is the source of much of the Earth's volcanic activity and helps to drive convection currents in the mantle that are responsible for the movement of heat and materials within the Earth.

Americans who are Deaf speak a different language, quite literally. Their language, American Sign Language (ASL), not only allows them to communicate with other Deaf people, but also gives them access to a linguistic subculture that not everyone has the opportunity to experience.

The use of additional facial emotions and personality are some of the main features of Black ASL.

Earthquakes typically result from subsurface rock breaking unexpectedly and rapid movement along a fault. The seismic waves that cause the ground to tremble are brought on by this quick release of energy.

Sudden tectonic changes in the earth's crust are what generate earthquakes. Orogeny, which causes earthquakes and volcanoes, is caused when the tectonic plates glide over one another. Vibrations produced by these disturbances travel in all directions.

Fractional crystallisation is the separation of two or more crystalline solids based on the differences in how soluble they are in the same solvent. The viscosity of the silica, which makes up the magma, increases with its concentration.

The term "fractional crystallisation" describes procedures that distinguish crystals from liquid. When this occurs, the liquid that is left over is regarded as a new magma. The crystals can be separated from a magma using a variety of techniques. Numerous minerals have denser compositions than the liquids they crystallise from.

Fractional crystallisation is essentially the removal of early-formed crystals from an initially homogenous magma, for instance, by gravity settling so that these crystals are stopped from further reacting with the remainder melt.

Mid Ocean Ridge is the boundary where the landforms would most likely be found, hence option (B) is the correct answer.

A seafloor mountain system created by plate tectonics is known as a mid-ocean ridge (MOR). It often extends above the deepest part of an ocean basin by about 2,000 meters (6,600 feet) and is roughly 2,600 meters (8,500 feet) deep.

Along a divergent plate border, this feature is where seafloor spreading occurs. The shape and width of the mid-ocean ridge in an ocean basin depend on the rate of seafloor spreading.

Mantle upwelling in reaction to plate separation creates new seafloor and oceanic lithosphere. The melt rises as magma at the line of weakness where the separate plates meet, then emerges as lava and cools to produce new oceanic crust and lithosphere.

Hence the correct answer is option (B).
