Understanding Sea-Level Rise and Thermal Expansion

What is one of the main contributors to sea-level rise besides melting ice?

• Tectonic plate movement

• Thermal expansion of ocean water

• Increased rainfall

• Increased river flow

Which item is NOT needed to set up the thermal expansion experiment?

• Clay or putty

• A water bottle

• A clear plastic drinking straw

• A metal spoon

Why is it important to keep the straw vertical when sealing the bottle?

• To prevent air from entering

• To ensure accurate water level measurement

• To make the experiment look neat

• To avoid spilling water

What should you do if you don't have a ruler to measure the water level?

• Use a string to measure

• Estimate the level visually and note it down

• Ignore the measurement

• Use a thermometer instead

What should you consider when applying heat to the water bottle?

• The color of the water

• The type of sealant used

• The size of the bottle

• The intensity of the heat source
