Option a, The crust's low density is what made it possible for it to develop as the Earth's outer layer.
High-density rock makes up the Earth's mantle, whereas lighter, lower-density rock came to the top to create the crust when the planet developed and cooled.
The heavier, higher-density rock was able to sink to the planet's core as a result of this differentiation process, while the lighter, lower-density rock persisted at the planet's surface.
The Earth's crust, which makes up the top layer of the planet, may float upon that mantle thanks to its low density.

all of the following reasons EXCEPT—
answer choices
over-grazing
air pollution
over-crowding
poor land management
Option b, Overgrazing, poor land management, and overcrowding are just some of the factors contributing to the increasing desertification of the Sahel region, the region between the Sahara and the savannah of Africa.
Land collapse and lack of vegetation have depended this area from a field into a desert.
Nevertheless, air pollution plays a minor role in desertification in the Sahel, as it is not a major and pressing concern in the region compared to other natural problems.
Maintaining the delicate balance of the Sahel's natural framework remains a challenge, and addressing the underlying causes of desertification is critical to prevent further loss of the Sahel's indigenous biological systems.

dynamothermal metamorphism occurs when a. rock becomes deeply buried during continental collision and mountain building. b. a metamorphic aureole forms in which hornfels develops. c. a pluton causes metamorphism in a small surrounding area. d. metamorphic reactions segregate different mineral types into different layers.
Dynamothermal metamorphism occurs when a. rock becomes deeply buried during continental collision and mountain building.
Formation process of metamorphic rocksMetamorphic 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).

As the south atlantic basin widens by seafloor spreading, africa and south america are moving closer together. T/F
True. As the seafloor spreads, the distance between Africa and South America is decreasing.
Why does seafloor spreading occur?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.
How does seafloor spreading affect Earth's surface?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.

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.

What do we call the top half section of the mantle?
The top half section of the mantle is called the asthenosphere.
Why is the mantle so important?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.
Why is the asthenosphere important?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.

which of the following best describes the direction of earth's rotation? group of answer choices eastward counterclockwise counterclockwise when viewed from the north pole; clockwise when viewed from the south pole, eastward when viewed from the equator. clockwise.
The correct answer is counterclockwise when viewed from the north pole; When seen from the south pole, the direction is clockwise; when seen from the equator, it is eastward.
Earth's rotation is a complex phenomenon, and its direction depends on the perspective from which it is observed. When viewed from the north pole, the Earth rotates in a counterclockwise direction, while when viewed from the south pole it rotates in a clockwise direction.
When viewed from the equator, it rotates in an eastward direction, though this is more of an illusion than a rotational direction. This is because the Earth's axis is tilted, so the direction of rotation appears to be eastward when seen from the equator.
The Earth's rotation is also affected by its orbit around the sun, as well as by factors such as the moon's gravitational pull, which can cause slight changes in the rotation speed.

Which of these landforms would most likely be found at a divergent boundary? answer choices. Fault line. Mid-ocean ridge. Volcanic island. Mountain.
Mid Ocean Ridge is the boundary where the landforms would most likely be found, hence option (B) is the correct answer.
What is a Mid Ocean Ridge ?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).
