The planet with a hot, turbulent atmosphere dominated by carbon dioxide is Venus.
1. Venus has an atmosphere that is mostly composed of carbon dioxide (over 96%) which creates a strong greenhouse effect, trapping heat and causing extremely high temperatures on the planet's surface.
2. Due to this thick layer of carbon dioxide and other gases, Venus has a runaway greenhouse effect leading to its scorching hot surface temperature of about 900 degrees Fahrenheit (475 degrees Celsius), making it the hottest planet in our solar system.
3. The turbulent atmosphere on Venus is characterized by high-speed winds that can reach speeds of up to 224 miles per hour (360 kilometers per hour) at its cloud tops, creating a chaotic and inhospitable environment.
In summary, Venus is the planet known for its hot, turbulent atmosphere dominated by carbon dioxide, which contributes to its extreme temperatures and harsh conditions.
