study the image about convection currents. at which location does heat transfer begin as dense material heats up? 1 2 3 4 trench lithosphere trench 1 3 4
Answer
Answer:
4
Explanation:
Step1: Understand convection process
Dense material heats up from the source.
Step2: Identify heat - source location
The core (4) is the heat source for mantle convection. Dense mantle material near the core heats up first, starting the convection current process.
