Its viscosity decreases, which allows it to flow easier.

When the temperature of lava increases, it becomes less viscous and flows more easily. This can lead to faster-moving lava flows and more extensive coverage of the surrounding area. Additionally, higher temperatures can also increase the likelihood of volcanic eruptions.
When the temperature of lava increases, its viscosity will decrease. Viscosity is a measure of the magnitude of internal friction of a substance.
The stratosphere's temperature increases as altitude increases. The mesosphere's temperature decreases as it's altitude increases. This is helpful
In the thermosphere, temperature increases with altitude due to the absorption of high-energy solar radiation by the sparse gas molecules present at that height. Despite this temperature increase, the thermosphere may feel very cold to us as the low density of molecules means that there is not enough matter to transfer heat efficiently.
As the angle at which the sun's rays strike the Earth's surface increases, the temperature tends to decrease. As the angle decreases, temperature tends to increase. At the same time, as the sun's angle decreases, shadows appear longer because the light is being cast at a greater angle.
As the altitude of the sun increases, the intensity of sunlight reaching the Earth's surface increases, leading to higher temperatures. This can result in warmer weather and more direct sunlight which is why midday tends to be the warmest part of the day.
The absolute magnitude of a start will increase both:* If its surface temperature increases, and * If its diameter increases.
