 The explanation given by Courtney regarding the extinction of the dinosaurs is true.

Further Explanation:

The dinosaurs were considered to be present on the Earth about ago. It is believed that the extinction of the dinosaurs was due to the effect of a very huge asteroid that hit the Earth.

The effect of the asteroid led to the formation of the huge cloud of dust in the atmosphere. This blocked the sunlight from entering the Earth and due to this, the temperature of the Earth reduced significantly and then as the cloud cleared, the greenhouse gases caused the increase in the temperature.

This sudden change in the climatic conditions of Earth led to the extinction of the dinosaurs. The scientists discovered a wide crater on the Earth hat signifies the impact of a huge asteroid.

Therefore, the explanation given by Courtney regarding the extinction of the dinosaurs is true.
