1. El Nino can cause changes in the prices of food.

True

False

El Nino is a weather phenomenon that occurs irregularly and affects global climate patterns. It can lead to extreme weather events such as droughts and floods, which can have a significant impact on agricultural production. These disruptions in food production can cause changes in the prices of food. Therefore, it is true that El Nino can cause changes in the prices of food.

These disruptions in food production can cause changes in the prices of food. Therefore, it is true that El Nino can cause changes in the prices of food.

2. El Nino causes fewer hurricanes in the Atlantic Ocean.

True

False

El Nino is a weather pattern characterized by warmer than usual ocean temperatures in the central and eastern Pacific Ocean. This phenomenon can have a significant impact on global weather patterns, including reducing the number of hurricanes in the Atlantic Ocean. The warmer waters in the Pacific can lead to increased wind shear in the Atlantic, which inhibits the formation and intensification of hurricanes. Therefore, it is true that El Nino causes fewer hurricanes in the Atlantic Ocean.
