Therefore, the correct statements are option A, option B, option C, and option A, and option C.
What are S waves?Earthquakes generate seismic waves that propagate through the crust of Earth. P waves travel through both solids and liquids causing the ground to compress.
S waves only travel through solids causing the ground to move perpendicular to the direction of the wave.
Surface waves travel along the surface of Earth and can make dramatic ground movements, that cause the most damage during earthquakes. These waves can violently shake structures when they reach the surface.
Therefore, the waves can travel through both solids and liquids are P waves, waves can travel only through solids are S waves, waves that can make dramatic ground movements are surface waves.

Answer:
Below
Explanation:
The answer is "the continental crush is the coolest region"
If you look at the graph, the lower the line goes, the farther down in the Earth it represents. And as the line moves to the right, it represents the heat getting greater. Therefore, the continental crush, which is represented at the very top and the line is farthest to the left, is the coolest region as the temperature increases with depth.

In this activity, you will write a description of the terrarium model you created to represent the different systems (spheres) of Earth. Make sure to include the words geosphere, biosphere, hydrosphere, and atmosphere in your description.
Answer:
Below
Explanation:
The geosphere refers to the land of the Earth.
The biosphere refers to all the living things on Earth.
The hydrosphere refers to all of the water in the Earth.
The atmosphere refers to the air on Earth.
To create a terrarium model, you could start by placing rocks all throughout the bottom of it. Pile up more on one side to create a hill. This represents the geosphere. Then, fill some of it with water. Make sure some of the rocks of that hill you made are still above the water, however. This represents the hydrosphere. Next, add a little plant or even a toy animal in to represent the biosphere. Finally, the remaining space represents the atmosphere, as humans can't see it so it's just clear.
The terrarium is a small, enclosed ecosystem that beautifully showcases the geosphere, biosphere, hydrosphere, and atmosphere in miniature form.
The geosphere is represented by the solid base of the terrarium, which mimics the Earth's crust and surface. Various rocks, pebbles, and soil are incorporated to depict the diverse landscapes found in the geosphere, such as mountains, valleys, and plains.
For the biosphere, added a selection of plants and small organisms. These living elements bring the terrarium to life, representing the complex interactions between flora and fauna found in the biosphere. Plants play a crucial role in converting carbon dioxide to oxygen through photosynthesis, simulating the vital connection between the biosphere and the atmosphere.
Next, the hydrosphere was depicted by a small, serene water feature within the terrarium. This mini aquatic environment captures the essence of Earth's oceans, rivers, and lakes, showcasing the interconnectedness of the hydrosphere with other systems. The water's presence also influences the microclimate, creating a more dynamic terrarium ecosystem.
Finally, the atmosphere is subtly indicated by the transparent walls of the terrarium, enclosing and safeguarding the entire model. This clear boundary represents the thin layer of gases surrounding Earth, providing protection and the right conditions for life to thrive within the terrarium's microcosm.
Thus, the combination of these different elements in the terrarium creates a harmonious representation of Earth's interconnected systems.

What observations and questions were asked that the geocentric model could not explain? please put a simple answer and no there are not choices because it is my notes
what is the geocentric model (please give simple answer and this is for my notes so there is no choices to pick from)
The geocentric model is a cosmological model that places the Earth at the center of the universe. This model was the prevailing view of the cosmos for centuries, and it was supported by the apparent daily movement of the Sun, Moon, and stars across the sky.
However, the geocentric model was eventually disproven by the heliocentric model, which places the Sun at the center of the universe.
The geocentric model was first proposed by the ancient Greek philosopher Ptolemy in the 2nd century AD. Ptolemy's model was based on the observation that the Sun, Moon, and stars all appear to move across the sky in a regular and predictable way.
He also observed that the planets appear to move in a looping pattern, which he explained by proposing that they orbit the Earth in a series of nested spheres.
Ptolemy's model was very successful in explaining the apparent motions of the Sun, Moon, and stars. However, it was not without its flaws.
For example, the model required the introduction of a number of epicycles, which were small circles that were attached to the larger circles that the planets orbited. These epicycles were necessary to explain the looping motion of the planets.
The geocentric model was eventually disproven by the heliocentric model, which was proposed by the Polish astronomer Nicolaus Copernicus in the 16th century.
Copernicus's model was based on the observation that the planets all orbit the Sun in the same direction, and that they all have nearly circular orbits. He also observed that the Earth rotates on its axis once every day and that it orbits the Sun once every year.

Fill in the blanks to complete each statement about energy in Earth’s crust. (use lower case wording only)
Plate movements on Earth’s crust create
.
This adds energy to the crust, which then bends and breaks, forming
.
Answer:
Plate movements on Earth's crust create stress. This adds energy to the crust, which then bends and breaks, forming faults.
faults = crack or fracture on the earth’s crust due to the displacement of rock due to earth movement.
Plate movements on Earth’s crust create tectonic stress. This adds energy to the crust, which then bends and breaks, forming faults and mountains.
Tectonic stress is the force that is created when two plates move against each other. This force can be compressive, tensile, or shear. Compressive stress is the force that pushes two plates together.
Tensile stress is the force that pulls two plates apart. Shear stress is the force that moves two plates past each other in a sideways direction.
When tectonic stress is applied to the crust, it can cause the crust to bend and break. This bending and breaking can form faults and mountains. Faults are cracks in the crust that can cause earthquakes. Mountains are formed when the crust is uplifted by tectonic forces.
