What is the average distance (approximate) between the Sun & the E...

The average distance between the Sun and the Earth is approximately 150 x 10⁶ kilometers, often referred to as one astronomical unit (AU). This distance serves as a fundamental unit for measuring distances within the solar system. Understanding this distance is crucial for studying celestial mechanics, planetary orbits, and astronomical phenomena. It's the baseline for calculating distances to other planets, asteroids, and celestial bodies, forming a key reference point in astronomical observations and calculations.

Directions:Read the passages and choose the best answer to each question.PassageEarth’s habitability is sustained by the sun. Currently, the sun provides enough light and warmth to maintain temperature conditions that can support life on our planet. It is undisputed that the sun is a star. All stars go through phases where they change in size, temperature, and brightness. Two scientists present their views on how long Earth will remain habitable.Scientist 1Earth’s sun has another 7 billion years before it enters the Red Giant phase. Currently, Earth could not sustain human life during the Red Giant phase. However, it is important not to believe that human life on Earth will immediately cease to exist as we know it in 7 billion years. Technology has played a huge role in helping humans adapt to conditions on this planet. We humans have 7 billion years to advance technology and ﬁnd solutions to adapt to the atmospheric changes the Red Giant phase would bring. For instance, creating a large sunshade to protect Earth would allow life to continue even when the sun enters the Red Giant phase. Another solution would be to develop technology that would stir the sun and bring new hydrogen to the sun’s core. This would greatly extend the current phase that our sun is in. There is enough time and incentive to discover ways to thwart the natural progress of nature. Therefore, I believe that human life on this planet will exist indeﬁnitely.Scientist 2The sun will enter its Red Giant phase in about 7 billion years. However, new models suggest that Earth has less than a billion years before atmospheric carbon dioxide levels drop to levels that can no longer support photosynthesis.This would lead to a dramatic temperature increase. Once Earth’s average temperature rises to above 70 C, the oceans will evaporate and Earth’s water sources will be almost completely eliminated. One billion years is not long enough for humans to evolve in order to meet large atmospheric and environmental changes, or to develop the technology needed to make Earth habitable. In a billion years, atmospheric changes will eliminate all life on Earth as we know it. Humans need to accept the reality that advanced life ﬂourishes for only a limited period of time. Science ﬁction— inspired plans to create space colonies or massive sunshades are unrealistic and will not likely be developed in the next billion years.Q.The views of both scientists are similar because they both argue that

The chart below depicts the average rainfall by location on the Earth. Zero degrees latitude corresponds to the equator. Positive latitudes are north of the equator, while negative latitudes are south of the equator. A latitude with a magnitude of 90 degrees correlates with one of Earths poles.Which best describes the rainfall trend between thirty and sixty degrees latitude?

There are two types of forces that occur with all substances on Earth. Intramolecular forces occur between atoms in a molecule, while intermolecular forces occur between neighboring molecules. Intermolecular forces can be dipole-dipole forces, hydrogen bonding, or London dispersion forces.Professor 1:Water molecules represent an example of hydrogen bonding due to the attraction between the hydrogen atoms and the oxygen atoms in the molecule. This strong dipole-dipole occurs due to lone pairs present on such atoms as Fluorine, Nitrogen, and Oxygen, which are able to pair more closely to the hydrogen atom in another nearby molecule. Water can be present in a solid, liquid, or gaseous state on Earth depending on the competition between the strength of intermolecular bonds and the thermal energy of the system. In 1873, a Dutch scientist, Van der Waals derived an equation that included both the force of attraction between the particles of a gas and the volume of the particles at high pressures. This equation led to a better fit for experimental data than the Ideal Gas Law.Professor 2:Water is the only substance on Earth that we routinely encounter as a solid, liquid, and gas. At low temperatures, the water molecules lock into a rigid structure, but as the temperature increases, the average kinetic energy of the water molecules increases and the molecules are able to move more creating its other natural states of matter. The higher the temperature, the more likely water is to be a gas. Water is proof of the kinetic theory, which assumes that there is no force of attraction between the particles of the gas state. The best fit for experimental data involving water in a gaseous form is found by using the Ideal Gas Law, since there is no interaction between the gaseous molecules. This law accounts for all of the forces that occur with gases on Earth.Q. Which of these statements made by professor 2 is not contradicted by professor 1?
