Answer the following question given this paragraph: Water flows through all the world's oceans. Warm water from the equator mixes with cold water from the poles. The mixing of warm and cold water makes the water temperature moderate. Q: Warm water from the equator mixes with cold water from where? A:

OPTIONS:
- the tropics
- the oceans
- the continents
- the poles

Answer: the poles

Problem: OPTIONS:
- accumulation
- frequency
- synchrony
- interference
Q: Answer the following question given this paragraph: Any two waves in the same medium undergo wave interference as they pass each other. At the location where the two waves collide, the result is essentially a summation of the two waves. In some places, a wave crest from one source will overlap a wave crest from the other source. Since both waves are lifting the medium, the combined wave crest will be twice as high as the original crests. Nearby, a wave trough will overlap another wave trough and the new trough will be twice as deep as the original. This is called constructive interference because the resultant wave is larger than the original waves. Within the interference pattern, the amplitude will be twice the original amplitude. Once the waves pass through each other and are alone again, their amplitudes return to their original values. Q: What is it called when two waves in the same medium pass one another? A:
Answer: interference

Problem:OPTIONS:
- pair bond
- neutron
- nucleus
- atom

Answer the following question given this paragraph: A polyatomic ion is an ion composed of more than one atom. For example, the ammonium ion consists of one nitrogen atom and four hydrogen atoms. Together, they comprise a single ion with a 1+ charge and a formula of NH 4 + . The carbonate ion consists of one carbon atom and three oxygen atoms, and it carries an overall charge of 2. The formula of the carbonate ion is CO 3 2- . The atoms of a polyatomic ion are tightly bonded together, so the entire ion behaves as a single unit. Figure below shows several models, and Table below lists many of the most common polyatomic ions. Q: A polyatomic ion is an ion composed of more than one what? A:
****
A: atom

Problem:OPTIONS:
- Pluto
- Mercury
- Jupiter
- mars

Answer the following question given this paragraph: Mars is the easiest planet to observe. As a result, it has been studied more than any other planet besides Earth. People can stand on Earth and observe the planet through a telescope. We have also sent many space probes to Mars. In April 2011, there were three scientific satellites in orbit around Mars. The rover, Opportunity, was still moving around on the surface. No humans have ever set foot on Mars. NASA and the European Space Agency have plans to send people to Mars. The goal is to do it sometime between 2030 and 2040. The expense and danger of these missions are phenomenal. Q: Which other planet in the solar system is the easiest to observe from earth? A:
****
A:
mars
