Challenge 3.3

Science
Chapter 3
3.3 review

During cold winters, ice can form on small lakes and ponds. Many people enjoy skating on the ice. Occasionally, a person skates on thin ice and breaks through it.
Why do rescue workers lie flat on the ice instead of walking upright when reaching out to help rescue a skater?

Because of their weight and elevation they would break the ice and fall into the water
