The atmosphere.
Cloud cover acts as a barrier or blanket preventing heat from rising into space. This is why deserts, with no cloud, are often extremely cold at night.
A blanket gets its warmth primarily from its insulating properties, which trap body heat and prevent it from escaping. The materials used, such as wool, fleece, or down, have fibers that create air pockets, providing thermal insulation. Additionally, the blanket's thickness and the type of weave can enhance its ability to retain warmth. Ultimately, a blanket acts as a barrier between the body and the cooler air, helping to maintain a comfortable temperature.
The heat from an electric blanket is generated through electricity passing through heating elements within the blanket. This radiant heat warms the body when the blanket is in use.
A wet blanket is a better heat conductor than a dry blanket because water is more conductive than air. The moisture in the wet blanket helps to transfer heat more efficiently from the body to the blanket.
An electric blanket generates heat through insulated wires inside the blanket. The heat is controlled by a thermostat, allowing you to adjust the temperature. The warmth you feel comes from the blanket's surface and can be adjusted to your comfort level.
An electric blanket uses conduction as the main source of heat transfer. The electric elements inside the blanket heat up, which transfers heat through direct contact with the body when the blanket is placed on top.

The atmosphere acts as a blanket, trapping heat from the sun and preventing it from escaping into space. Without this greenhouse effect, the Earth's surface would rapidly cool down, leading to inhospitably cold temperatures.
The thick atmosphere of Venus acts like a blanket, similar to the green house effect, and traps the suns heat extremely well.
Heating a blanket primarily involves conduction, where heat is transferred through direct contact between the blanket and the heat source. Some heat may also be transferred through convection, as air around the blanket absorbs heat, rises, and circulates. Radiation plays a minor role as the blanket may emit some heat in the form of infrared radiation.
The heat blanket should go below the top sheet on the bed. Placing the blanket between the mattress and the top sheet helps to distribute the heat evenly and prevents direct contact with your skin, which can be uncomfortable.
An electric blanket transfers heat primarily through conduction, as the electric coils inside the blanket warm up and directly heat the body when in contact.
