ANSWER KEY: Practice EOG Questions – Hydrosphere 1 & 2

1)D – groundwater

2)OMIT – but answer is d) surface tension

3)OMIT – but answer is a) cohesion – I MADE A MISTAKE ON YOUR PRACTICE SHEET :0

ADHESION is when water sticks to OTHER things (such as the side of a glass) 

4)b) 97% FRESH = 3% (remember THE CUPS  )

5)OMIT – but answer is a) cohesion – water sticking to water

6)C) water vapor

7)C) neritic zone (covered with water – think about being up to your NECK (neritic) in water 

8)C) intertidal zone (the area between the water & the beach, where you walk along the beach but the waves come in) Think about what the word says…INTER – Tidal (where tide rolls in)

9)A) polar ice caps (mostly Antarctica & Greenland)

10)C) crab (benthos – you have to BENd down to reach where the crab lives)

11)D) plankton – more specifically –“PHYTOplankton – phyto means “plant like” – phytoplankton (photosynthetic) is responsible for MORE CO2 (carbon dioxide) conversion to O (oxygen) than ALL the other plants on earth put together!!! :0 HUGE part of the global carbon cycle. Think it is kind of IMPORTANT Lil Darlings!!

12)A) flood irrigation

13)A) canal

14)A) chlorine

15)B) POINT – source pollution

HYDROSPHERE 2:

1)B) liquid water, frozen water, & water vapor

2)B) in cracks & spaces in rocks - REMINDER: AQUIFER MUST HAVE 3 THINGS 1) water (aqua) 2) permeable rock – allows water to flow through it (ex: gravel, sand) & impermeable rock – allows water to be stored (ex: concrete, granite, brick)

3)A) it is less dense than cold water REMINDER: Cold water & cold water SINKS –more dense

Warm water & water air RISES – less dense

4)A) sound waves

5)B) winds……this is why we LOVE for it be windy at the beach..boogie boards baby…body surfing! 

6)D) density

7)C) habitat

8)B) salt marshes & mangrove forests (WARM water – think of Florida)

9)A) intertidal zone (tide comes in, goes out; receives sun and then no sun; salt from water and then no salt when water goes out; crashing waves….

10)B) on the DEEP – ocean floor. Hydrothermal vents are the “energy” source for many deep ocean organisms (HYDRO = water; THERMAL = energy/heat)

11)D) chemicals released by the vents into food

12)B) fish at a faster rate than they can reproduce. Harmful to environment. This is why we have “aquacultures” – areas where fish can reproduce quickly & safely. These fish are sometimes used as food for OTHER bigger fish
