Identify the role of atmosphere in climate control from the given options:

1. The atmosphere regulates the temperature on Earth as it is a poor conductor of heat.

2. The greenhouse gases present in the atmosphere absorb sunlight and keep the climate warm during the day.

3. During the nights, the atmosphere inhibits the complete loss of the trapped heat and prevents the freezing of the planet.

4. The ozone layer prevents harmful UV rays from penetrating into the atmosphere and protects us from skin cancer and painful sunburns.
