The quote states that we should be using solar energy before our limited amount of naturally occurring oil and coal runs out. Meaning; we should be proactively working towards solar power rather than to wait for our resource to run out to start.
The physical processes on Earth create constant change. These processes—including movement in the tectonic plates in the crust, wind and water erosion, and deposition—shape features on Earth's surface.Lithospheric Processes cause magmatism, mantle dynamics, and faulting, which in turn shape the Earth's ever-changing surface.
The four common Planet Surface Processes are: Cratering, Volcanoes, Erosion, and Weathering (chemical and physical).The Earth's surface is constantly changing through forces in nature. The daily processes of precipitation, wind and land movement result in changes to landforms over a long period of time. Driving forces include erosion, volcanoes and earthquakes.
Lithospheric Processes. Lithospheric Processes cause magmatism, mantle dynamics, and faulting, which in turn shape the Earth's ever-changing surface. ... We also study the high temperature systems in the Earth's interior that produce magmas, drive metamorphism, and create mantle heterogeneity.
