In a solar eclipse, the moon blocks the light from the sun casting a shadow in some areas on the earth. Why is the moon able to block the light from the sun when the moon is very small compared to the sun?

Question 9
9.
You hear on the news that a new computer program tracks the patterns of solar and lunar eclipses. This program predicts that the next total solar eclipse will happen on August 21 of next year. Your friend asks why this doesn’t happen in a regular pattern every moon phase cycle like the other phases of the moon. Explain why.

Hugh visited Alaska during the Summer of 2014 and was impressed with the fact that the sun was up, bringing daylight, nearly all day! She planned a return trip in the Winter of 2015 and was disappointed when she found the days short and the hours of daylight. Which scientific phenomenon helps to explain why was this the case?

Question 17

Two students are in an argument about why the planets stay in orbit and do not fly off into space. They decide to create a model by spinning a tennis ball inside of a hula hoop. They observe that the hula hoop keeps the tennis ball in a circular motion, similar to the planets’ orbits. Which BEST explains how the students’ model relates to the orbits of the planets around the sun?

Question 20
20.
The four planets closest to the Sun are called the inner planets. They are considered terrestrial planets, meaning they are made of rock. Some of them have a thin atmosphere of gas surrounding the planet. The core is the inner part of the planet and made up mostly of metals like iron and nickel.
The four outer planets are gas giants. These planets are very far from the Sun. They don't have a hard surface that a spacecraft can land on. Instead, they are giant balls of very cold gases. Astronomers think that these planets have hot, solid cores deep beneath their atmospheres.
Which of the following conclusions can be drawn from the evidence above?
