The Ancient Maya writing system, which used symbols to represent sounds and words, is called hieroglyphics or hieroglyphs. This system of writing was used by the Maya civilization in Mesoamerica from about the 3rd century BCE until the Spanish conquest in the 16th century. Hieroglyphic texts were inscribed on stone monuments, pottery, and bark paper books, and they provide a wealth of information about Maya culture, history, and religion. The complexity of Maya hieroglyphs was not fully deciphered until the 20th century, with the work of scholars such as Yuri Knorosov and Linda Schele.

how does it explain the differences between seafloor and continental crust? every time a bit of rock is subducted and expelled, its chemistry changes, making it heavier. the heavier rock becomes the seafloor plates, while the relatively unprocessed rocks are the continental plates.
The composition and formation of the continental crust and the seafloor are what distinguish them from one another.
While granite, which is produced by the solidification of magma beneath the Earth's surface, makes up the majority of the continental crust, basalt, which forms from solidified lava that has erupted from mid-oceanic ridges, makes up the majority of the seafloor crust.
Multiple sizable plates that make up the Earth's lithosphere move and interact with one another along their boundaries. An ongoing cycle of the formation and destruction of seafloor crust occurs at mid-oceanic ridges as magma rises up and solidifies.

which mechanical layer of the earth is plastic and completely solid?
The mechanical layer of the earth that is plastic and completely solid is the mantle.
The mantle is located between the crust and the core and is composed of solid rock that can flow over long periods of time due to the high temperature and pressure conditions within the earth. This flow is what gives the mantle its plasticity, allowing it to slowly move and cause tectonic plate movements. Despite its plasticity, the mantle is still considered a solid layer of the earth, as it maintains a solid state due to the intense pressure that exists within the earth. The mantle is an incredibly important part of the Earth's structure, playing a crucial role in maintaining the planet's magnetic field and regulating the movement of its tectonic plates. The asthenosphere extends from approximately 80 to 200 kilometers (50 to 120 miles) below the Earth's surface, and its temperature ranges from 1,300 to 1,500°C (2,370 to 2,730°F).

The news media often report an earthquake's magnitude on the richter scale. Which items are characteristics of a richter earthquake magnitude?
Answer:
The Richter Scale is a measurement of the magnitude of an earthquake. The following are characteristics of a Richter Earthquake Magnitude:
It is a logarithmic scale: The Richter Scale is a logarithmic scale, meaning that the energy released by an earthquake increases exponentially with each whole number increase in magnitude. For example, an earthquake with a magnitude of 6.0 is 10 times more powerful than an earthquake with a magnitude of 5.0.
It measures the amplitude of seismic waves: The Richter Scale measures the amplitude of seismic waves, which are the vibrations that travel through the Earth's crust during an earthquake. The amplitude is determined by measuring the maximum height of the waves recorded by a seismograph.
It has no upper limit: The Richter Scale has no upper limit, meaning that theoretically, there is no limit to the magnitude of an earthquake that could be recorded. However, in practice, the largest earthquake ever recorded had a magnitude of 9.5.
It is widely used: The Richter Scale is one of the most widely used measures of earthquake magnitude, and it is often reported by the news media after an earthquake.
It is not the only scale: While the Richter Scale is a widely recognized measure of earthquake magnitude, there are other scales that are also used, such as the moment magnitude scale and the Mercalli intensity scale. These scales measure different aspects of an earthquake, such as the total energy released or the level of damage caused
Explanation:
The Richter scale is a logarithmic scale used to measure the magnitude of an earthquake.
The scale ranges from 0 to 10 and each whole number increase represents a tenfold increase in the earthquake's amplitude. Some characteristics of a Richter earthquake magnitude include the amount of energy released, the size of the fault rupture, and the depth of the earthquake's epicenter.
Earthquakes with a magnitude of 3.0 or lower are generally not felt, while those with a magnitude of 7.0 or higher can cause widespread damage and loss of life. The Richter scale is often used by the media to quickly and easily communicate the severity of an earthquake to the public.
However, it is important to note that the scale does not necessarily indicate the extent of damage caused by an earthquake, as factors such as distance from the epicenter and soil conditions can also play a significant role.

What are the three most common gasses dissolved in magma?
Explain what happens along the boundary and why it causes the formation of trenches.
The boundary where two tectonic plates meet, one plate is forced beneath the other into the Earth's mantle. This process is known as subduction. The denser plate, typically an oceanic plate, sinks beneath the less dense plate, usually a continental plate, creating a trench.
The oceanic plate subducts, it begins to melt due to the increasing temperature and pressure in the Earth's mantle. This molten rock, called magma, rises up towards the Earth's surface and can cause volcanic activity. Additionally, the subduction of the oceanic plate causes earthquakes and tsunamis.
The formation of trenches occurs because the subduction zone where the plates meet is typically the deepest part of the ocean. As the oceanic plate sinks, it creates a depression in the ocean floor which eventually becomes a trench. Trenches can be thousands of kilometers long and several kilometers deep. They are important geological features as they help us to understand the movement and interactions of tectonic plates.
Boundaries are the areas where two tectonic plates interact with each other. There are three types of boundaries: convergent, divergent, and transform. Trenches are formed along convergent boundaries, specifically where an oceanic plate is subducting beneath a continental plate or another oceanic plate.
As the denser plate is pushed downward, it creates a deep depression in the ocean floor, known as a trench. This process is driven by the movement of Earth's mantle, which causes the plates to move and interact with one another.
The subducting plate is pulled deeper into the mantle, and the trench continues to deepen. The intense pressure and heat at these depths cause the subducting plate to partially melt, which can lead to the formation of volcanoes and earthquakes along the boundary.

Earthquakes: Name the damaging phenomenon in which water-saturated sediment becomes fluid during seismic shaking, causing heavy objects on the surface to sink in?
The phenomenon you are referring to is called liquefaction
Liquefaction occurs when water saturated sediment, which is typically composed of loose, sandy soil becomes destabilized during seismic shaking. The shaking causes the grains of sand to rearrange themselves, and the water that fills the spaces between the grains is forced to the surface, where it forms a layer of quicksand like material.
The liquefied sediment loses its ability to support weight, and heavy objects on the surface may sink or tilt. Buildings and other structures built on top of liquefied sediment are also at risk of collapsing or sustaining damage.
Liquefaction is a common phenomenon in areaswith loose, water saturated sediment, such as river deltas and coastal plains, and can occur during earthquakes of all magnitudes.
