Explanation / Answer

27) What kind of plate boundary is the San Andreas Fault associated with ?

Ans. a) Transform.

San Andreas Fault is a transform fault associated with Pacific Plate and the North American Plate, that is, it forms the boundary between Pacific Plate and the North American Plate.

28) The planets, Moon, and the Sun lie along nearly the same plane called the __________ and therefore move along the same region of the sky.

Ans. b) ecliptic.

This is an imaginary plane or maybe called an invisible plane along which The planets, Moon, and the Sun lie. And this is called ecliptic.

29) What type of plate boundary is illustrated in the above figure ?

Ans. d) Divergent.

This is an divergent plate boundary. The well develiped rift valley, normal faults, volcanoes, pillow lavas and association of these all features with the oceanic crust point towards the divergent plate boundary.

30) Which is the most abundant element in the Earths Crust ?

Ans. Oxygen.

Oxygen is the most abundant element in the Earths crust, nearly 46.6%. The second most abundant element is Silicon, nearly 28%. Then aluminium (nearly 8%) and iron (nearly 5%).
