Why did Peruvian fishermen call the event El Niño?

• Because it occurred near Christmastime

• Because it happened during the rainy season

• Because it caused droughts in Asia

• Because it improved fishing opportunities

How often does El Niño occur?

• Every ten years only

• Every two to seven years

• Every few months randomly

• Every year without fail

What did scientists confirm about El Niño?

• It only affects Peru

• It has no effect on economic activities

• It causes changes in global weather patterns

• It only happens during the 19th century

Which regions are affected by El Niño?

• Europe and Antarctica

• Greenland and Canada

• Asia, Africa, and North America

• South America only

What does El Niño demonstrate about climate?

• Weather is always unpredictable

• Only humans influence climate

• Local events are not connected globally

• Climate conditions are part of a global system

Which of these is a major factor influencing climate?

• Wind and ocean currents

• Types of animals

• Population growth

• Soil composition

What is convection?

• Transfer of heat in the atmosphere by upward motion

• Rotation of the earth on its axis

• Movement of water in oceans only

• Erosion caused by wind and rain

How is wind created?

• By cooler dense air moving into low-pressure zones

• By rainfall evaporating

• By the movement of tectonic plates

• By ocean waves crashing

Why don’t winds blow in straight lines?

• Mountains block the flow

• The earth’s rotation bends winds

• Winds move randomly without cause

• The moon affects wind direction

What is the Coriolis effect?

• Circulation of ocean currents

• Increase in temperature at the equator

• The warming of waters near Peru

• Bending of winds due to earth’s rotation
