Answer:The Earth's lithosphere is relatively hard rigid-like whereas, the asthenosphere is relatively hot and plastic-like

Answer: A constructive plate boundary creates ridges
Explanation: A constructive plate boundary, sometimes called a divergent plate margin, occurs when two tectonic plates move apart. Volcanoes are formed as magma wells up to fill the gap and molten rocks from the mantle below spread out and harden, eventually forming a ridge of new land/rock. The Mid-Atlantic ridge is an example of a constructive plate boundary.
