In the lessons

In science, submarines submerge by filling tanks with water and surface by blowing it out — a lesson on floating and sinking. In geography, floods submerge roads and fields. In safety lessons: never drive or walk through submerged roads — water can be deeper and faster than it looks. In maths and science, you find the volume of an object by submerging it and measuring the rise in water.

Examples

• The submarine began to submerge. tree →

Note

Spelling: drop the e before -ing (submerging). "Sub-" means under. Opposite: surface, emerge. Volume trick: the rise in water = the volume of the submerged object.
