Thermal+Expansion+of+Water+and+Sea+Level

Your topic is the characteristic of water called thermal expansion and how it will play a role in the change in sea level during a climate change event. Group Members: Meghan Powers Dellon Myette John David (Did not participate) Rachel St. Onge  Final Grade- Organization 4/5 Good set-up, bottom part still not connected well though.. Climate change explanation 6/10 Still no connection between atmosphere heating up and the oceans heating up. Oceanography explanation 15/15 This section is good enough for your topic, focus on the other ones! Diagram/connection to text 7/10 Good diagrams but there is the top one still has no real explanation Overall 32/40 Thermal Expansion and It's Affect On Water and Sea Level Thermal Expansion is the increase in volume of a material as temperature increases. In terms of water it is more easily understood as an increase in volume rather than an expansion. When climate change occurs, for example becomes warmer, the volume of the water will increase. The diagram below demonstrates the relationship between temperature and volume.  <span style="font-family: 'Times New Roman', Times, serif;">( Diagram taken from: <span style="font-family: 'Times New Roman', Times, serif;">http://www.lsbu.ac.uk/water/strange.html <span style="font-family: 'Times New Roman', Times, serif;">)

Since the ocean is several miles deep, this factors out to be about a foot, giving a change in the sea level. In turn, the beach line moves landwards 20 feet .<span style="background-color: rgb(150,209,227);"><span style="background-color: rgb(255,255,255);"> The increase in ocean volume caused by increasing temperatures could potentially threaten sea side communities or areas close to sea level. Thermal expansion is a very important part of oceanography. It must be studied and observed so we are able to collect more data. It gives us clues to how climate change and global warming are affecting the planet. =====

If the water in a lake or pond increases, it's not going to do all that much and it only affects the small area around it. But if the ocean increases in volume, that affects a much greater area and in result a lot more people. =====

As the ice hats up, it adds to the volume of the ocean, creating a higher sea level rise, and diminishing more coastline.
