11. Water that soaks into the ground is called ________ water.

Answer key with explanations

#	Answer	Why
1	b	Evaporation means liquid becomes gas when heated
2	c	Vapour is invisible; we see clouds because it has already condensed into droplets
3	d	Fog is a cloud near the ground; nothing falls from it
4	False	Water evaporates all year, just more slowly when it's cold
5	True	This is called transpiration
6	True	Earth doesn't get new water; the same water keeps cycling
7–9	C, A, B	Order of the cycle: condense → fall → collect
10	cools	Cold air holds less vapour, so droplets form
11	ground	Groundwater feeds wells and springs

Teacher tip: before worksheet 2, show a cold glass "sweating" in a warm room. Pupils who saw it get question 7 right far more often.
