KCSE Geography Paper 1 2013 Section B Question 7.

(a) Name the first two planets of the solar system.

Mercury
Venus

(b) Explain the origin of the earth according to the Nebula Cloud Theory.

The explosion of the stars led to the formation of a huge cloud of gases (hydrogen and helium), dust and ice particles.
This cloud whirled, cooled and condensed to a disc shape.
The gravitational attraction within the materials increased cause the particles to compact. Some particles broke from the edge of the disc and whirled.
The compacted particles swirled faster towards the centre of the disc in different directions. As they whirled they cooled or solidified to form the planets.
This swirling caused particles to collide losing a little energy at a time.
The middle of the spinning disc condensed to form the sun while the material spinning around condensed into large chunks of materials called planetoids.
The planetoids collided and coalesced into large bodies called planets.
The earth is one of the planets.
The centre of the disc formed the sun.

KCSE Geography Paper 1 2016 Section A Question 1.

(a) How does a sea breeze occur?

During the day, the land heats faster than the sea
The air over the land rises
Cooler air from the sea blows towards the land to replace the rising air
The cool air from the sea is called the sea breeze

(b) Use the map of Africa below to answer question (b) (i)

(i) Name the ocean currents marked H, J and K.

H-Mozambique/Agulhas
J-Benguela
K-Guinea

(ii) State two effects of a warm ocean current on the adjacent coastlands.

It warms up the adjacent land
It increases the humidity of the adjacent land
It may lead to rainfall on the adjacent land

KCSE Geography Paper 1 2017 Section A Question 3.

(a) Name three features that make up the hydrosphere.

Oceans
Seas
Lakes
Rivers
swamps
Ice sheets

(b) Explain how the movement of magma causes earth movement.

The molten rock (magma) is forced to intrude into the earth’s crust through a line of weakness causing displacement.
The crustal rocks are forced to move/give way to intruding magma as their place is taken over by the intruding magma.

1⁰ = 4 Mins

47⁰ x 4 = 188 mins = 3hrs 8 mins

Buchanani is 3 hrs. 8 mins behind Nairobi its time will be 6.52 am (2mks)

b) What is the effect of the international date line on time?(2mks)

On crossing this longitude while going to west, a day is lost while a day is gained while crossing to the East. (2mks)
