Answer the following question given this paragraph: A proton is one of three main particles that make up the atom. The other two particles are the neutron and electron. Protons are found in the nucleus of the atom. This is a tiny, dense region at the center of the atom. Protons have a positive electrical charge of one (+1) and a mass of 1 atomic mass unit (amu), which is about 1.67 10 -27 kilograms. Together with neutrons, they make up virtually all of the mass of an atom. For an excellent video on protons and other fundamental particles in atoms, go to this URL:. Q: Which atomic particle has a positive charge? A:

the proton

Answer the following question given this paragraph: The rise in greenhouse gases due to human actions is too much of a good thing. It increases the greenhouse effect and causes Earth's average temperature to rise. Rising global temperatures, in turn, are melting polar ice caps and glaciers. Figure below shows how much smaller the Arctic ice cap was in 2012 than it was in 1984. With more liquid water on Earth's surface, sea levels are rising. Q: The rise in greenhouse gases has what effect on the temperature of earth? A:
OPTIONS:
- no effect
- more moderate
- it drops
- it increases

Answer: it increases

Q: Answer the following question given this paragraph: Every moment of every day is a field trip to gravity. Gravity is everywhere! You have a gravitational attraction to your dog. You have one to your pencil. You even have one to your school principal! These gravitational attractions are very small compared with the most important one you have. This is your gravitational attraction to Earth. It's what keeps you from floating off into space. Gravity holds our planet together. Gravity keeps Earth orbiting the Sun. We wouldn't be here without gravity. Q: What keeps the earth orbiting the sun? A:

OPTIONS:
- variation
- inertia
- speed
- gravity

A: gravity

Answer the following question given this paragraph: Reflection is one of several ways that light can interact with matter. Light reflects off surfaces such as mirrors that do not transmit or absorb light. When light is reflected from a smooth surface, it may form an image. An image is a copy of an object that is formed by reflected (or refracted) light. Q: What is a copy of an object that is formed by reflected light? A:
OPTIONS:
- deflection
- instance
- example
- image
image
