When the sky is clear, heat from the Earth's surface radiates directly into space, leading to faster cooling. Clouds act as a barrier, trapping heat and reflecting it back towards Earth, which slows down the cooling process.
When sky is clear the heat from earth will radiate to space and cool the night air faster. If cloudy the heat radiated is reflected back from clouds and it does not get so cool
On a clear night, temperatures tend to drop more rapidly as heat escapes into the atmosphere. Cloudy nights act as a blanket, trapping some heat and causing temperatures to not drop as much as on clear nights. This can result in warmer temperatures on cloudy nights compared to clear nights.
Dew forms on clear nights because the ground loses heat through radiation, causing temperatures to drop. As the temperature falls, moisture in the air condenses on surfaces when they cool below the dew point. Conversely, on cloudy nights, clouds act as an insulating layer, trapping heat and preventing the ground from cooling sufficiently for dew to form. This is why dew is more likely to occur on clear nights compared to cloudy ones.
The Earth formed 4.6bn years ago, and the temperature of the core is currently 5200°c, and it's projected to go cold in something like 90bn years time, which is irrelevant as the Sun will turn into a Red Giant in around 5bn years time, engulfing the Earth and completely destroying it, so to answer your question, it takes a VERY long time for the Earth to cool down- so long in fact, that it will actually NEVER cool down.
At night, the Earth cools down by radiation as heat from the surface is emitted into the atmosphere. This radiation escapes into space, causing the temperature to drop. Clear skies with low humidity allow for more efficient cooling because there are fewer clouds and water vapor to trap the heat at the surface.

Lava on the earth's surface will cool quickly.

Igneous rocks that cool quickly beneath earth's crust are known as intrusive rocks. These rocks will form from magma which will cool and solidify quickly.

Clouds and high humidity act as a blanket to hold in heat at night. If these are absent, the heat absorbed by the earth during the day quickly radiates back into space.
Water bodies like lakes or rivers tend to cool quickly due to their high specific heat capacity. On land, materials like metals, rocks, or concrete can cool quickly as they conduct heat away rapidly. Clear nights with minimal cloud cover can also lead to rapid cooling of the Earth's surface.
The cloudy weather brings us cool weather because of the air without air we will die.

The lack of clouds means that the desert will heat up quickly when the sun rises but will also cool down quickly when the sun goes down.
No metals do not cool off quickly.
