Sinkholes only occur where sand forms landforms.

Sinkholes do not occur in Florida.

If filled with water, sinkholes may become sinkhole lakes.

Sinkholes are caused by the erosion of rock by water.

Answer 1

True statements:
- Florida has rock that is easily eroded by water. (Florida sits on soluble limestone/karst.)
- If filled with water, sinkholes may become sinkhole lakes. (These are often called sinkhole lakes or cenotes.)
- Sinkholes are caused by the erosion/dissolution of rock by water. (Water dissolves or removes soluble bedrock, creating voids that collapse.)

False statements:
- Sinkholes only occur where sand forms landforms. (False — they occur where soluble bedrock like limestone, gypsum, or salt is present, not where sand is dominant.)
- Sinkholes do not occur in Florida. (False — they do occur in Florida.)
