Tectonic evidence is the best one to complete the diagram, as it shows a crack in the Earth's crust which is most likely a fault, which is a fracture in the Earth's crust where rocks have moved past each other.
Faults are caused by the movement of tectonic plates, which are the giant slabs of rock that make up the Earth's crust.
Meteorological evidence is evidence that has to do with the weather, such as temperature, precipitation, and wind but there is no meteorological evidence in the diagram. Physiochemical evidence is evidence that has to do with physical and chemical processes, such as erosion and sedimentation and there is no physiochemical evidence in the diagram.
Weather evidence is evidence that has to do with the short-term conditions of the atmosphere, such as temperature, precipitation, and wind and no weather evidence in the diagram.
