The ground shakes during an earthquake because of (c) seismic waves
When an earthquake occurs shockwaves of energy, called seismic waves, are released from the earthquake focus. They shake the Earth and temporarily turn soft deposits, such as clay, into jelly
Seismic waves are caused by the sudden movement of materials within the Earth, such as slip along a fault during an earthquake. Volcanic eruptions, explosions, landslides, avalanches, and even rushing rivers can also cause seismic waves.
Seismic waves are usually generated by movements of the Earth’s tectonic plates but may also be caused by explosions, volcanoes and landslides. Seismologists use seismographs to record the amount of time it takes seismic waves to travel through different layers of the Earth. As the waves travel through different densities and stiffness, the waves can be refracted and reflected. Because of the different behavior of waves in different materials, seismologists can deduce the type of material the waves are travelling through.
There are three basic types of seismic waves – P-waves, S-waves and surface waves. P-waves and S-waves are sometimes collectively called body waves.
P-waves
P-waves, also known as primary waves or pressure waves, travel at the greatest velocity through the Earth.
S-waves
S-waves, also known as secondary waves, shear waves or shaking waves, are transverse waves that travel slower than P-waves
Surface waves
Surface waves are similar in nature to water waves and travel just under the Earth’s surface. They are typically generated when the source of the earthquake is close to the Earth’s surface. Although surface waves travel more slowly than S-waves

The correct answer is option C.
In sedimentary rocks, mature sedimentary grains are well sorted.
What are sedimentary grains?Sedimentary grains are units of sedimentary rocks and mature sedimentary grains are well-sorted because they have a uniform appearance.
More specifically, these grains are well rounded and are of similar size and shape, and also exhibit similar composition with a little variation in their appearance.
On the contrary, immature grains have a variety of shapes and sizes and are more rounded, and show a diverse composition with a large degree of variation.
Simply put, the chemical composition of sedimentary grains shows that they are either organic or inorganic material that is formed as a result of weathering of rock fragments and are carried away and deposited by wind and water, etc.

What is civil wars?A civil war is a bloody battle that takes place on the territory of a state between that state and one or more coordinated non-state actors. Thus, civil wars are distinguished from border disputes, violent conflicts or riots that don't involve states, and state repression of people who can't be categorized as members of an organized or cooperative group, including genocides, as well as from similar violence by non-state actors, like terrorism or violent crime.
Most civil conflicts occur in civilizations that are comparatively less wealthy. Early research on the causes of violence in civilizations tended to emphasize economic hardship and personal grievances.

how does the inward drop in air pressure cause heat to be added to a hurricane that is over the ocean?
Once an air parcel reaches the hurricane's eyewall, it turns upward and rises due to a process called convection.
The inward drop in air pressure in a hurricane allows inward flowing air to cool below the sea-surface temperature, which in turn allows more heat to flow in from the sea.
Due to low pressure at its center, twists stream toward the focal point of the tempest and air is constrained vertical. High in the climate, winds stream away from the tempest, which permits additional air from underneath to rise. The air that ascents should be warm and wet so it frames the billows of the tempest.

Deep-focus earthquakes that don't fit the pattern. Here option B is the correct answer.
Generally speaking, earthquakes deeper than 70 km are referred to as "deep-focus earthquakes." All earthquakes that occur deeper than 70 km are restricted to large lithosphere slabs that are sinking into the Earth's mantle. H.H. Turner of Oxford, England, discovered the proof for deep-focus earthquakes in 1922.
At convergent plate borders, when a thick oceanic plate collides with a less dense continental plate and falls beneath the latter, the deepest earthquakes take place inside the core of subducting slabs, oceanic plates that drop into the Earth's mantle.
Unfortunately, surface damage from earthquakes tends to increase with depth; intermediate and deep-focus earthquakes seldom cause significant damage.

Sediment is deposited horizontally, according to the original horizontality concept. With liquids, it can be sometimes simpler to picture this: picture pouring water into a cup. The water's surface is absolutely horizontal and flat. That water stays flat when you pour it into a bowl. According to the Law of Original Horizontality, all rock layers were initially deposited horizontally and are therefore susceptible to deformation.

what effect will continued seafloor spreading in the atlantic ocean have on east coast and gulf coast sea level?
The result is The Atlantic Ocean grows 1.5 inches wider every year. That's because the tectonic plates undergirding the Americas are separating from those beneath Europe and Africa.
The earth's covering is broken into huge sections called structural plates. The plates are in sluggish ceaseless development. The seafloor spreading definition is the geologic interaction that happens at the limit between 2 plates where liquid material inside the earth pushes its direction up, making the plates get away from one another. At these unique limits liquid material cools and solidifies, making new maritime outside or ocean bottom. New outside layer is being made even today, but the earth's size is not increasing because elsewhere at certain convergent boundaries plates collide..

Which directly contributed to soil erosion on the great plains in the 1930s?the homestead actrailroadsheavy rainsfarming.
Farming directly contributed to soil erosion on the great plains in the 1930s. When soil is removed from a location on the landscape, it is called soil erosion.
Wind and water are the two primary causes of soil erosion. Climate generally affects what kind of erosion takes place. Strong winds and a generally dry climate in the Great Plains contribute to the region's extensive wind erosion. For instance, on May 12, 1934, winds transported roughly 200 million tons of soil from the Southern Great Plains 1,500 miles to the Atlantic Ocean. Loose, finely divided, dry soil on a bare, smooth surface are the ideal circumstances for wind erosion.
Suspension, saltation, and surface creep are the three mechanisms by which wind erosion moves soil. Large distances can be covered by suspension of very small particles (less than 0.05 mm in diameter). When the wind speed is lowered or they are washed away by rain, the particles lose their suspension and fall to the ground.

The description which best presents the arrangement of continents, oceans, and landforms according to the theory of plate tectonics is the motion of lithospheric plates over millions of years.
A tectonic plate, sometimes referred to as a lithospheric plate, is a sizable (enormous), solid rock slab with an uneven shape that is typically composed of two (2) primary plates: Continental dinnerware, marine plates.
According to the idea of plate tectonics, the solid outer crust of Earth (lithosphere) is separated into enormous slabs of solid rock (plates), which normally migrate through the asthenosphere over millions of years, including the upper part of the mantle.

the gravitational field strenght on the moon is 1.63n/kg. if a rock on the moon weights 2000n, how much does the same rock weigh on the earth?
Newtons per kilogram (N/kg) is used to measure the gravitational field strength (g). At or near the surface, the gravitational field strength of the Earth is 10 N/kg. This implies that an item will experience 10 N of force for every kilogram of mass.
The weight of an object is smaller if the gravitational field is weaker. The Moon, for instance, has a gravitational field that is 1.6 N/kg strong. This indicates that an object will encounter 1.6 N of force for every kilogram of mass. An astronaut will therefore be lighter on the Moon than they are on Earth.
Weight is the gravitational force exerted on an object; it is measured in newtons (N) and is directed toward the gravitational field's center. A spring balance, which is frequently referred to as a newton meter and is calibrated in Newton, can be used to determine an object's weight.
