Albedo
Albedo is the fraction of incident radiation that is reflected by a surface. Different materials reflect different amounts of the incoming light and thus have different albedo values, which range from 0 (0 percent reflected) to 1 (100 percent reflected).
Why does land heat faster than water?
This is because land has a smaller “heat capacity” than water, which means it needs less heat to raise its temperature. The chart below shows how the Earth's land surface (yellow line) has warmed more rapidly than the ocean (dark blue) over the observational record.

Copy and paste the sentence starter and fill it in.
Which heats up faster land or ocean and how do you know. Use evidence from the video to explain.
Sentence Starter: The video shows us that ________ heats up faster than _________. The reason why we know this is that from the graph we can see that _________ increases to a temperature of______, while the other only reaches a temperature of _______ (which is lower).

Have you ever wondered why the sand at the beach practically burns your feet while the water stays refreshing.
It takes a lot more _______ to break the hydrogen bonds that hold water _______ together. Water, because of this, can take in a lot more heat before the temperature _______ dramatically.
Therefore the balloon with water in it was kept intact. This models the ocean keeping from rising in temperature _______ .
The moving water mixes up the heat from the sun and diffuses it through a bigger _______ , while the land remains stagnate. The Sun's rays are also able to puncture deep into water so that the bulk of the heat isn't just sitting on the _______ layer of the ocean, like it does on _______ .

Weather vs. Climate
Weather refers to short term atmospheric conditions while climate is the weather of a specific region averaged over a long period of time. Climate change refers to long-term changes.
So, for example, it may be 75° degrees and sunny or it could be 20° degrees with heavy snow. That's the weather. Climate is the average of that weather. For example, you can expect snow in the Northeast in January or for it to be hot and humid in the Southeast in July.
