water cycle

Question 1

what is evoperation

Answer 1

evoporation occur when a liquid changes into gas and occur at a range of temperatur

Question 2

where does evoparation occur

Answer 2

surface of the liquid

Question 3

what happen to ke during evoparation

Answer 3

they move faster

Question 4

what happen to the intermoleculer space during evoparation

Answer 4

force of acttraction decreases and the inter molecular space increases

Question 5

what is condenseation

Answer 5

when gas change to liquid

Question 6

what happen to ke in condensation

Answer 6

lose energy and mov slower

Question 7

what happen to intermoleculer space in condensation

Answer 7

force of attraction increases and the intermolecular space increases

Question 8

what is freezing

Answer 8

liquid changing to solid

Question 9

what happen to ke during freezing

Answer 9

lose energy and vibrate in the position

Question 10

what happen to the attraction during freezing

Answer 10

get stronger and are able to stop the particles from moving freely

Question 11

what is melting

Answer 11

solid changing to liquid

Question 12

what happen to ke in melting

Answer 12

require heat to transform into ke allowing the particles to move

Question 13

when does melting occur

Answer 13

specific temperature known as the melting point

Question 14

what is ke

Answer 14

movment of particles due to heating

Question 15

proporties of matter are

Answer 15

all matter is made up of small particles
the particles are moving all the time
heavier particle move slowly than lighter particles at the same temperature

Question 16

what is diffusion

Answer 16

random movment of particles from high concentrston to lower concentration until they are evenly distributed

Question 17

what are the stages involved in water cycle

Answer 17

evoparation
condensation
precipitation
runoff

Question 18

what happen to sea water during evoparation

Answer 18

salanity of sea water increases

Question 19

what are the factors effecting rate of evoparation

Answer 19

temperature, wind increases evoparation
humidity decreases evoparation
rainfall decreases evoparation

Question 20

what is precipitation

Answer 20

water realesed from cloud in form of rain or snow

Question 21

what precipitation help in forming

Answer 21

land based ince in cold region

Question 22

how does run off occur

Answer 22

by flowing into a river or through ground water

Question 23

what is surface run off

Answer 23

due to rain and melting ice and snow causes surface runoff this result in the dissolving of mineral and nutrients from land to sea

Question 24

what are the benifit of sarface run off

Answer 24

it help many algea phytoplankton to grow which is feed by other organism

Question 25

disadvantage of surface run off

Answer 25

pollute water with sediment contaminating land area turbid water kill water animal reduce light penetration-less photosynthesis
