Students were creating graphs to illustrate the energy transformations that occur as a roller coaster moves along a track. The letters A-D on Graph 1 represent the position of a roller coaster as it moves along a track. The numbers 1-4 on Graph 2 were supposed to represent the energy of the roller coaster at positions A-D, but the students got their data mixed up. How should the bars in Graph 2 be ordered so that they match to the energy of the roller coaster as it moves from position A to B to C to D?

A- it's at the top and not moving so its all potential
B- Bottom so no potential, a little is lost to friction- a little thermal, it's moving so ther'es kinetic
C- in the middle hieght- some potential, lost more to friction so more thermal, not moving so no kinetic
D- bottom, so no potential. more energy lost to friction. still moving so some kinetic

Which of the following statements is correct with regard to convection currents?
A. Convection currents in magma are caused by color differences.
B. Convection currents in magma drive the movement of tectonic plates.
C. Convection currents in magma are a result of how the magma is formed.
D. Convection currents in magma play a role in the movement of Earth's inner core.
Answers
Answer:
A.convection currents in magma are caused by color differences
The thermal conduction we find that the correct answer is:
a) Convection currents in magma are caused by hot differences.
Thermal conduction occurs in three ways
Conduction. When two material are in thermal contact with different temperatures, energy flows from the hottest material to the coldest, in this there is no material movement Radiation. Due to the absorption of radiant energy between bodies with different temperatures, it does not need physical contact, which is why it is the form of transmission in a vacuum. Convention. This occurs when a mass of liquid or gas is in contact with another colder mass and the material of the hotter mass moves upward in the cold mass, this form of heat transfer includes the movement of material, it is very important in liquid and gases.
The magna of volcanoes is a quantity of matter in a liquid or plastic state due to the thermal energy of the interior of the earth, when this mass reaches a colder and fissured area, it can rise towards the coldest part, breaking and deritating. the materials in its path.
Let's annotate the different statements
a) True. According to the explanation, the temperature of the magna causes it to rise due to convection currents.
b) False. The cracks are those that help the convection currents, in general the movement of the plates creates cracks
c) False. The movement of the plates is independent of the convection of the magna which is approximately vertical
d) False. The core of the planet is very deep (> 4000 km) and the magna currents reach about 14 to 20 km
In conclusion using the forms of thermal conduction we find that the correct answer is:
a) Convection currents in magma are caused by hot differences.

1. What could scientists learn by using the Law of Superposition?
2. How could this help people learn about earthquakes?
3. Is there any way to determine when the magma actually intruded with these clues only?
4. Could we use fossils to help determine the age of rocks (and thus the age of magma intrusions)?
5. What other methods could scientists use to date rocks?
Answers
Answer:
Explanation:
1.The Law of Superposition is a fundamental principle of geology that states that in a sequence of undisturbed layers of sedimentary rocks, the oldest rocks are at the bottom and the youngest rocks are at the top. Scientists can use this law to determine the relative ages of rocks and the order in which they were deposited.
2.The Law of Superposition can help people learn about earthquakes because it provides a way to study the history of the Earth's crust and the geological forces that have shaped it over time. By studying the layers of rock and the patterns of deformation and displacement caused by past earthquakes, scientists can develop a better understanding of how earthquakes occur and how they may impact different areas in the future.
3.It may be possible to determine when the magma intruded by using additional clues, such as the presence of index fossils, the type of rocks present in the intrusion, and the relative ages of the surrounding rock layers. However, these clues would need to be interpreted in the context of other geological features and events in the area to arrive at a reliable estimate of the age of the intrusion.
4.Yes, fossils can be used to help determine the age of rocks, including magma intrusions. Certain types of fossils, known as index fossils, are useful for dating rocks because they are known to have existed only during a specific period of time. By identifying the index fossils in a rock layer, scientists can determine its approximate age.
5.Other methods that scientists can use to date rocks include radiometric dating, which involves measuring the decay of radioactive isotopes in minerals, and paleomagnetic dating, which uses the record of Earth's magnetic field preserved in rocks to determine their age. These methods can provide absolute ages for rocks and are often used in conjunction with the Law of Superposition to develop a more complete understanding of the history of the Earth's crust.

Explain how the formation of atoms affects the mass of a substance provide specific examples in your explanation.
Answers
Answer:
ummm not good so I got this from my teachers textbook
Explanation:
Most of the Universe consists of matter and energy. Energy is the capacity to do work. Matter has mass and occupies space. All matter is composed of basic elements that cannot be broken down to substances with different chemical or physical properties. Elements are substances consisting of one type of atom, for example Carbon atoms make up diamond, and also graphite. Pure (24K) gold is composed of only one type of atom, gold atoms. Atoms are the smallest particle into which an element can be divided. The ancient Greek philosophers developed the concept of the atom, although they considered it the fundamental particle that could not be broken down. Since the work of Enrico Fermi and his colleagues, we now know that the atom is divisible, often releasing tremendous energies as in nuclear explosions or (in a controlled fashion in) thermonuclear power plants.The atomic number is the number of protons an atom has. It is characteristic and unique for each element. The atomic mass (also referred to as the atomic weight) is the number of protons and neutrons in an atom. Atoms of an element that have differing numbers of neutrons (but a constant atomic number) are termed isotopes. Isotopes, shown in Figure 1 and Figure 2, can be used to determine the diet of ancient peoples by determining proportions of isotopes in mummified or fossilized human tissues. Biochemical pathways can be deciphered by using isotopic tracers. The age of fossils and artifacts can be determined by using radioactive isotopes, either directly on the fossil (if it is young enough) or on the rocks that surround the fossil (for older fossils like dinosaurs). Isotopes are also the source of radiation used in medical diagnostic and treatment procedures.
