Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. How heavy is Tidewater glacier cycle?Calving of icebergs into the marine environment
2. What is the location?Polar and subpolar coastal regions, including Alaska, Greenland, and Svalbard
3. What is the influencing factors?Ocean temperature, basal melt, tidal forces, and ice flow dynamics
4. What is a tidewater glacier?A tidewater glacier is a giant river of ice that flows into the sea and can break off into icebergs. It ends in seawater.
5. How does a tidewater glacier melt and break off ice?It melts faster because it touches warmer ocean water, and waves, tides, and meltwater undercut the ice, making it break off.

Basal Lubrication: The presence of meltwater at the glacier's base, reducing friction and increasing flow speed.
Ocean Stratification: The layering of ocean water based on density, often influenced by temperature and salinity.
Geomorphological Legacy: The landforms and features created by past geological processes, such as glaciation.
