WebApr 11, 2024 · At the starting speed of 80 km/h and 100 km/h, the radius of vertical curve is 7000 m, and the carbon emission per unit distance of the car is 185.7 g/km and 187.5 g/km respectively, with a difference of 1.8 g/km. This shows that the starting speed has little influence on the carbon emission per unit distance of the car. Geothermal gradient is the rate of temperature change with respect to increasing depth in Earth's interior. As a general rule, the crust temperature rises with depth due to the heat flow from the much hotter mantle; away from tectonic plate boundaries, temperature rises in about 25–30 °C/km (72–87 °F/mi) of depth near the surface in most of the world. However, in some cases the tem…
