Answer to Question 1

TRUE

Answer to Question 2

Trenches are the deep places in the oceans where denser basaltic plates are subducted beneath lighter continental ones. The heat of this subduction always gives rise to volcanic chains immediately above the subduction zone, such as the Nazca Trench off South America and the Andes immediately east of it.
