He African continent is home to the world's largest desert and longest river.

GarryVolchara [31]

<h2>Answer: False</h2>

The longest river in the world in is the Amazon, located in South America, with a length of 6800 kilometers, compared to 6695 of the Nile River.

It is understandable that for a long time it was believed that it was the Nile. However, a few years ago the Brazilian Institute of Geography and Statistics published an investigation claiming that the Amazon is the longest river in the world.

On the other hand, the Sahara Desert itself is the largest (warm) desert in the world, <u>but</u> the Antartic Desert occupies the first place with an area of $13,829,430km^{2}$ compared to $9,065,253 km^{2}$ of the Sahara.

Taking into account that the definition of desert is a place with very little or no rainfall in the year.

<h2>Therefore this is false.</h2>

AleksAgata [21]

Predicting where an earthquake epicenter will occur is easier because are patterns to look at due to the fact that they always occur near plate boundaries. Predicting when they will occur is difficult because they do not follow any certain pattern.
