How might volcanic eruptions change the flow of energy on earth?
Answer:
It causes global warming due to emission of carbondioxide gas.
Explanation:
Volcanic eruptions change the flow of energy on earth by emitting gases such as carbondioxide and sulfur dioxide gases. Volcanic gases like sulfur dioxide is responsible for global cooling by reflecting solar radiation back to the space, while on the other hand, carbon dioxide emitted from volcanoes, has the ability to promote global warming by blocking solar radiation. If the amount of carbondioxide gas is higher as compared to sulfur dioxide gas so global warming occurs.
Which statement describes how maps represent Earth's surface? They have a three-dimensional surface. They use symbols to represent land features. They all use the same scale to show distance. They accurately represent the relative shape of Earth.
Answer:
B. They use symbols to represent land features.
Explanation:
In Geography, topography can be defined as the shape and structure of the Earth surface. Thus, a topographic map is used to graphically describe this features.
A topographic map can be defined as an accurate and detailed graphical (two-dimensional) description, representation or records of both natural and man-made (artificial) features on the surface of the Earth.
A topographic map uses contour lines to represent points of equal elevation above sea level such as mountains, hills, plains, valley etc.
The two-dimensional model of a topographic map graphically represents the height of a mount and the steepness of a slope through the use of contour lines.
Contours can be defined imaginary lines used for connecting locations that are having similar elevations on the Earth's surface. These contour lines are typically used for modeling the three-dimensional shape of the Earth surface in a topographic map.
Hence, the statement which best describes how maps represent Earth's surface is that, they use symbols to represent land features.
Answer:
B. They use symbols to represent land features.

The three states of matter are modeled in the heating curve seen here. Identify ALL of the changes that must take place for a substance to change state, from a solid to a gas
A) Pressure increases
B) Temperature increases.
C) Particles spread apart.
D)Kinetic energy increases.
E) Particle motion increases.
Answer: B, C, D, E
Explanation:
In a generalised manner B, C, D and E takes place for a substance to change state, from a solid to a gas.
What is phase transition?The physical process of changing a medium's state from one to another is known as a phase transition. The phrase is frequently used to describe transitions between the three fundamental states of matter—solid, liquid, and gas—and, in rare instances, plasma.
Heat must be used to provide energy for molecules to go through phase change. The intermolecular connections that keep the substance in its current state are broken using this energy. When the element receives enough energy, the phase change will occur.
Without going through the liquid state, sublimation is the process by which a substance moves straight from the solid to the gas state.

Should the thruster fire exert force in the same direction or opposite direction to bring the Pod to a stop? Explain.
Answer: Explain the claim : Firing the thrusters would have caused the pod to move in the opposite direction. The pod would have had to have a lighter mass meaning a smaller amount of force would have had to be exerted onto the pod making it move in the opposite direction.
