Gaaffii 1

According to the chapter, what is climate change?

A.A long-term change in the usual climate of the planet, such as temperature, precipitation and wind, especially caused by human activities
B.A change in the weather that happens for one day only
C.A change caused only by volcanic eruptions
D.A change in the height of ocean tides

Deebii fi sababa agarsiisi

Deebii: A A long-term change in the usual climate of the planet, such as temperature, precipitation and wind, especially caused by human activities

Sababa

The chapter defines climate change as a global change in the usual climate (temperature, precipitation and wind), especially caused by human activities, over multiple decades or longer. Weather for one day is not climate change, and volcanoes are not the main cause.

Gaaffii 2

Which of these is not listed in the chapter as one of the major greenhouse gases?

A.Water vapour
B.Carbon dioxide (CO<sub>2</sub>)
C.Methane
D.Oxygen

Deebii fi sababa agarsiisi

Deebii: D Oxygen

Sababa

The chapter lists water vapour, carbon dioxide, methane and nitrous oxide as the major greenhouse gases. The chapter says oxygen and nitrogen do not absorb and radiate heat the way greenhouse gases do.

Gaaffii 3

The chapter says the average temperature of the earth is kept at 14°C by the greenhouse effect. Without the greenhouse effect, what would the temperature drop to?

A.14°C
B.40°C
C.-18°C
D.0°C

Deebii fi sababa agarsiisi

Deebii: C -18°C

Sababa

The chapter states that without the greenhouse effect, temperatures would drop to as low as -18°C, which is too cold to sustain life on earth.

Gaaffii 4

Which human activity increases the concentration of atmospheric CO₂, according to the chapter?

A.Planting new forests
B.Burning fossil fuels such as coal, oil and gas
C.Rainfall
D.Strong winds

Deebii fi sababa agarsiisi

Deebii: B Burning fossil fuels such as coal, oil and gas

Sababa

The chapter says humans increase atmospheric CO₂ by burning fossil fuels, cutting down forests and farming livestock. Among the choices, only burning fossil fuels is one of these named activities. Rainfall and winds are natural processes, not human causes.

Gaaffii 5

According to the chapter, increases in atmospheric CO₂ are responsible for about what share of the total energy imbalance that is causing the earth's temperature to rise?

A.One-third
B.About two-thirds
C.All of it
D.One-tenth

Deebii fi sababa agarsiisi

Deebii: B About two-thirds

Sababa

The chapter says increases in atmospheric carbon dioxide are responsible for about two-thirds of the total energy imbalance that is causing the earth's temperature to rise.

Gaaffii 6

In which year was Ethiopia's Green Legacy Initiative launched?

A.2007
B.2011
C.2019
D.2010

Deebii fi sababa agarsiisi

Deebii: C 2019

Sababa

The chapter says the Green Legacy Initiative (GLI) was launched in 2019. The 2007 plan was the National Adaptation Plan of Action, and the CRGE strategy came in 2011.

Gaaffii 7

In which year was the Kyoto Protocol adopted?

A.1992
B.2009
C.1997
D.1994

Deebii fi sababa agarsiisi

Deebii: C 1997

Sababa

The chapter states that the Kyoto Protocol was adopted on 11 December 1997. The UNFCCC was agreed in 1992, and the Copenhagen meeting (COP15) was in 2009.

Gaaffii 8

A cyclone moves at 62 km per hour near a coastal town. How far does it travel in 3 hours? Use the speed from the chapter.

A.124 km
B.60 km
C.206 km
D.186 km

Deebii fi sababa agarsiisi

Deebii: D 186 km

Sababa

The chapter says cyclones move at sixty-two km per hour or more. Distance = speed × time, so 62 × 3 = 186 km. The other choices come from wrong multiplication or from using the wrong number.

Gaaffii 9

A fisherman at a coastal village in Ethiopia notices that the sea has suddenly pulled far back from the shore. What should he do first, according to the chapter's tsunami advice?

A.Walk out onto the exposed sea floor to look at the fish
B.Move inland to higher ground immediately
C.Wait on the beach until the water comes back
D.Stay near the shore and take photos

Deebii fi sababa agarsiisi

Deebii: B Move inland to higher ground immediately

Sababa

The chapter says a noticeable recession in water away from the shore is nature's tsunami warning and should be heeded. The correct action is to move inland to higher ground immediately and stay there.

Gaaffii 10

According to the chapter, what causes most earthquake-related deaths and injuries?

A.Being in open ground during the shaking
B.Ground movement during the earthquake itself
C.Collapsing walls, flying glass and falling objects
D.Tsunami waves that follow every earthquake

Deebii fi sababa agarsiisi

Deebii: C Collapsing walls, flying glass and falling objects

Sababa

The chapter says ground movement is seldom the direct cause of death or injury. Most earthquake-related casualties result from collapsing walls, flying glass and falling objects. This is why people are told to stay away from glass and to take cover.
