Understand the Problem
The question is asking about the layers of the Earth and their characteristics, specifically focusing on which layer is described as plastic or semi-solid, what defines the lithosphere, false statements about convection currents, and processes associated with tectonic plates.
Answer
1) Mantle, 2) The Earth's crust and a thin part of the upper mantle, 3) Convection currents in the fully liquid layer (false), 4) Subduction.
The answers are: 1) Mantle, 2) The Earth's crust and a thin part of the upper mantle, 3) Convection currents happen in the fully liquid layer of the Earth, 4) Subduction.
Answer for screen readers
The answers are: 1) Mantle, 2) The Earth's crust and a thin part of the upper mantle, 3) Convection currents happen in the fully liquid layer of the Earth, 4) Subduction.
More Information
The mantle is semi-solid, allowing for convection currents; the lithosphere includes the crust and upper mantle; false statement about convection currents is they occur in a fully liquid layer; subduction involves one tectonic plate sinking under another.
Tips
Don't confuse the layers of Earth with each other or the processes taking place within them.
