https://padlet.com/bcahusac1/sealevel1 What have you learned about climate change and the differences between land ice and sea ice melting? en-us 2016-02-29 18:24:00 UTC 2024-05-29 06:35:06 UTC hello@padlet.com https://padlet.com/bcahusac1/sealevel1/wish/100275600 Global warming is causing many things. It is melting glaciers, causing droughts, and many other things that could possibly end up being uncontrollable. One of the biggest reasons is that sea levels are rising. Why? See the next slide to figure out. ]]> 2016-03-10 17:19:05 UTC https://padlet.com/bcahusac1/sealevel1/wish/100275600 ljimenez34_2 https://padlet.com/bcahusac1/sealevel1/wish/100275909 Ice glaciers are melting and  this causing sea levels to rise and swamp coastal areas all over the world.
Why is this bad?
*it will contaminate our drinking water
*It will threaten wild life populations. 
Many animals live on the beach, as water sea levels are rising animals like turtles and shorebirds will suffer. Their nests will also be swept by flooding and more. Not only that but is sea levels rise enough there is a better possibility that we will experience more flooding, tsunamis and other natural disasters. Right now people are ignoring the problem and are doing some to help it but not enough. Sea levels rising can cover cities and towns underwater which could kill many people. Also, solid water or ice is very cold and has to be cold to stay in its form. If the ice melted it would still be cold so the sea temperature would also decrease which could lead to people freezing by even touching the water.  Wildlife would also be threatened. Like  sea animals in which we call food like fish sometimes have certain temperatures of the water to be able to survive and more. it would displace millions of people that live in coastal cities and low lying islands too.

Well particles are the main reason. Land ice or glaciers melt faster that sea ice because of the particles bumping against the land ice are different. the particles that bump off of the land ice or glaciers are air particles. Air particles move faster and have more heat that water particles. So when particles are moving fast and there is heat in them they spread heat faster and they bump into particles more because they are faster and so the solid or water particles also consume a lot of that heat from the air particles when they bump against each other. When water particles bump against a solid and transfer their heat the solid does not get as much heat as it does from air molecules because water particles have little space in between them and can rotate and move little so they don´t bump into the solid particles as much and as fast. That is the reason behind why land ice melts faster than sea ice using the particle theory.

The one with the ice in the funnel made the water increase by 20.4 mm and the other one with water ice melted by .4 mm. So the land ice melted faster than the water ice melted.]]> 2016-03-10 17:38:54 UTC https://padlet.com/bcahusac1/sealevel1/wish/100282274 https://padlet.com/bcahusac1/sealevel1/wish/100282299 We can stop using so much energy one computers and stop using your car as much, and if you can you can stop using planes so much. Why? Because now at days a lot of our energy is made by burning fossil fuels like coal. Also methane from livestock let out the same gas that keeps heat in the atmosphere. We are constantly keeping more livestock globally for meat, milk, transportation and more. Instead we can help by using, solar energy, wind energy and we could start by producing more solar panels, wind turbines, and other clean energy resources that might be more expensive but are better for the earth. Many people are using solar energy and other natural energy recourses but not enough. Most of the world still relies on fossil fuels and livestock which is exactly what we have to change.]]> 2016-03-10 17:38:59 UTC https://padlet.com/bcahusac1/sealevel1/wish/100282299 https://padlet.com/bcahusac1/sealevel1/wish/100514878 2016-03-11 17:12:58 UTC https://padlet.com/bcahusac1/sealevel1/wish/100514878 https://padlet.com/bcahusac1/sealevel1/wish/100516119 2016-03-11 17:17:55 UTC https://padlet.com/bcahusac1/sealevel1/wish/100516119 https://padlet.com/bcahusac1/sealevel1/wish/100927087 While the ice was melting for our little experiment on if land ice or sea ice melt faster we did some research about ice sheets and how Florida would be affected if the western ice sheet melted as well as the eastern and how Florida was before hand. Before Miami, Jacksonville, and New Orleans were completely on land with water at the borders and an equal amount of land and water. Apparently 20,000 years ago global sea levels were about 400 feet lower than they are now. Coastlines around the world are very different from how they were then the difference changes depending on where you are.  If the western ice sheet melted the water would have flooded some of the coastlines leaving Jacksonville in the middle of land and water, and Miami and New Orleans on land. What really surprised me is what would happen if the eastern ice sheet melted. It would leave Jacksonville, Miami and New Orleans completely covered with water and the coastlines flooded. When we studied the picture we saw that there was more water than there was land and for me what was interesting was that 20,000 years ago there were some lakes and rivers close to Miami and New Orleans. Now if the eastern ice sheet melted those lakes and rivers were not covered in water anymore but land and I didn't understand why.]]> 2016-03-15 00:39:47 UTC https://padlet.com/bcahusac1/sealevel1/wish/100927087 https://padlet.com/bcahusac1/sealevel1/wish/103031520 I thought the sea ice would melt faster but I was wrong the land ice melted faster]]> 2016-03-29 12:57:03 UTC https://padlet.com/bcahusac1/sealevel1/wish/103031520 https://padlet.com/bcahusac1/sealevel1/wish/103031760 I thought that the ice in the water would melt faster but it turned out that the land ice melted faster because the land temperature was at a higher level than the sea temperature.]]> 2016-03-29 12:57:56 UTC https://padlet.com/bcahusac1/sealevel1/wish/103031760 https://padlet.com/bcahusac1/sealevel1/wish/103032056 I thought that land ice would melt faster, because it is not in cold water. and sea ice is.

Cows and humans producing lots of methane along with our own waste and more.
