Passage: The sea is blue for the same reason that the sky is blue. The blue of the sea is caused by

the scattering of sunlight by tiny particles suspended in the water. Blue light, being of short wave

length, is scattered more efficiently than light of longer wave lengths.

Although waters of the ocean are commonly some shade of blue, especially in tropical or subtropical

regions, green water is commonly seen near coasts. This is caused by yellow pigments being

mixed with blue water; Microscopic floating plants (Phytoplankton) are one source of the yellow

pigment. Other microscopic plants may wlor the water brown or brownish - red. Near the shore

silt of sediment in suspension can give waters a brownish hue; outflow of large rivers can often be

observed many offshore by the coloration of suspended soil particles.

i) All ocean water is the same shade of blue

a) in all places

24

b) at all times

c) hardly ever

d) because all light waves are the same length

ii) Blue light is

a) a short wave length

b) a long wave length

c) about equal to all other wave lengths

d) not scatterable.

iii) Green water near coastlines is almost always caused by

a) sand color

b) red pigments in coastal waters

c) blue pigments

d) reflected light and yellow pigment from plant life

iv) Phytoplankton are

a) short light rays

b) suspended soil particles

c) microscopic floating plants

d) long light rays

v) The main idea of this passage is

a) light causes sea color

b) sea coloration is varied because of a combination of length of lightwaves and microscopicplant life and silt.

c) microscopic plantlife causes sea color

d) water composition causes sea color

b) Explain the features of good paragraphs. 7 Marks
