This results in food coloring pooling on top or run down the side of the ice. As a result, sea level does not rise when sea ice melts. Sea ice occurs in both the Arctic and Antarctic. In one tub, place as many ice cubes as possible on the flat clay surface. Because of the slow process of heat diffusion in water, the world’s oceans are likely to continue to warm for several centuries in response to increases in greenhouse concentrations that have taken place so far. Therefore, when it melted off of the “land” and dripped into the water, it added volume. How does this compare to your prediction? An increase in global temperature caused by anthropogenic warming influences the quantity of polar ice. Ask them to specify if the ice is on land or at sea. Compare sea level rise of melted sea ice vs land ice. Use the measurements recorded on the data sheet to create a line graph representing the water level in each tub. Both thermal expansion and ice melt are the results of the rise in global average temperatures on land and sea known as climate change. The most basic difference is that sea ice forms from salty ocean water, whereas land ice (ice sheets and glaciers) form from fresh water or snow. The ice in the Arctic is frozen seawater and therefore considered sea ice.). Sea and Land Ice Melt Ice is found all around our planet, from the highest peak in Africa to the icy North and South Poles. Students should be able to connect the model to the global events of ice melting and associated sea-level rise. The melting of ice that sits on land (an ice sheet) or on the ocean (sea ice) has profoundly different consequences for global sea level and climate.This Activity introduces students to several different kinds of ice (including glaciers and icebergs) and invites them to simulate and measure the different effects of melting ice on the ocean and on land. Groups should take measurements and record data at regular intervals. 6 inches by 6 inches, Clay (enough to fill about a quarter of each tub with 1-2 inches of clay). Use the data from the student data sheet to create a line graph using spreadsheet software. As a class, discuss sea-level rise and climate change. In the other tub, place the same number of ice cubes on the bottom of the tub, next to the clay. This represents land ice. ‘’Arctic Ocean Sea Ice’’ [Online]. Ice on Earth – Download PDF (2.8 MB) January 2018 This month, EO Kids is covering a “cool” topic in Earth science. Tell students they’re going to conduct an experiment to learn how melting ice contributes to sea-level rise. Fresh water is less dense than salt water and warm water is less dense than cold water; these differences cause circulation in the ocean which is referred to as thermohaline circulation. They conduct two experiments, one looking at sea ice and the other looking at land ice and observe how the melting of this ice affects the sea level. This represents land ice. Tell students they’re going to conduct an experiment to learn how melting ice contributes to sea-level rise. Sea level rise is a natural consequence of the warming of our planet. Both types of ice range over vast areas of the polar regions. The experiment allows them to test whether land ice and/or sea ice contribute to sea level rise as they melt. In what way is this related to global sea-level rise? The land ice however was not included in the original measurement of the water which contained the sea ice. Formulate your hypothesis, then click "play" to find out! Finally, glac… In the Southern … On the other hand, land ice refers to any form of ice formed on land and lasts for more than a year. , Sea ice forms in the winter months and melts in the summer months, however in certain regions it remains year round. GRACE … This absorption heats up the ocean causing further more melting of ice. Once the barrier is gone, glacial ice melt entering the ocean would increase the sea level. Is added into the ocean the ocean absorbs 90 % of the world 's oceans covered. Currently below the long-term average of all decades prior since 1979 example, if the entire West Antarctic sheets.
