What would happen if the Earth lost all gravity for 5 seconds? What would happen if Earth's gravity became as big as Jupiter for 5 seconds?

if it lost or gained all life would end

Explanation:

lost for five seconds

1:all things not firmly attached to the ground would start to float eg cars ships people or mid air floods

2;the atmosphere would drift into space causing lack of enough oxygen

3:the Earth's crust starts to expand outwards causing earthquakes and volcanic eruptions etc

4:the earth would drift away

if was like Jupiter's

1:all the blood in your body would pool at the bottom making the heart work harder to supply blood to other areas

2:the earth crust would start moving inwards therefore collapsing from the inside out

3all the satellites in the orbit would come crashing down etc

hope it helps

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
