• Water appears in nature in all three common states of matter (solid, liquid, and gas) • Water is tasteless and odorless • Water is a good polar solvent and is widely referred to as universal solvent • Water covers 71% of the Earth's surface • Water has a high specific heat • Water has a high heat of vaporization. • Water's greatest density occurs at 4C
2. Construct a graph showing water distribution
Earth’s Water Distribution
3. As future teachers what will you do to prevent or control water pollution? Since my specialization is teaching, the least thing I could do is to educate my future pupils and the people around me about the effects of water pollution and what we can do about it even by ourselves. I would teach them what changes water pollution has brought to our environment.
4. Draw waves and label the parts
5. Do waves that are close together have a longer or shorter wavelength than waves that are far apart? Waves that are close together have shorter wavelength but higher frequencies. While those waves that are far apart have longer wavelength have lower frequencies.
6. What happens to the wavelength as waves approach shores? The wavelength decrease and the height increases. The pressure also eases down.
7. What force causes the tides to occur on Earth’s surface? Tides on Earth’s surface are caused by the moon’s gravitational pull as well as the Sun’s gravitational pull. However, the Sun’s gravity is much weaker on Earth’s surface than the moon’s gravity since the Moon is much closer to Earth than the Sun.
8. Describe one factor that affects the height of the tides in a particular area.
One factor that affects the heights of tides in a particular area is because of the nature of the sea floor, and how deep or shallow the seas or ocean.
