Where water is found on Earth W1-mt_nRF_VRntrW-s1

  1. Water in its solid form · Ice is solid water. Freezing changes liquid water into ice.
  2. Water vapour, rivers, groundwater · Water vapour is in the air, rivers are surface stores, and groundwater is below ground.
  3. False · Ice and snow are solid water, so not all water is liquid.
  4. Oceans · Most of Earth's water is in the oceans, not rivers or underground stores.
  5. Solid water · Glacier ice is solid water. Slow movement does not make it liquid.
  6. 2 · Cloud droplets and water vapour are found in the air. That makes two cards.
  7. A piece of glacier ice broke into the sea. · An iceberg comes from glacier ice breaking into the sea. Freezing sea water produces sea ice instead.
  8. It is water held in spaces in soil and rock. · Groundwater can occupy spaces in soil and rock. It does not need a huge cave or underground lake.
