What is half the size of earth has two moons and has a atmosphere of mostly carbon dioxide?
The planet that is half the size of the earth, has 2 moons, and has an atmosphere of mostly carbon dioxide is Mars. The average length of a day on Mars is 37 minutes longer than that of the Earth.
What are two of the driest places on earth?
Two of the driest places on earth are the Atacama Desert in Chile and the McMurdo Dry Valleys in Antarctica. These regions receive very little precipitation and have extremely low humidity levels, making them some of the driest places on the planet.
Identify the two major reservations of carbon dioxide on earth?
The two major reservoirs of carbon dioxide on Earth are the atmosphere and the oceans. Carbon dioxide is exchanged between these reservoirs through various processes such as photosynthesis, respiration, and ocean-atmosphere exchange.
What percent of Earth's atmosphere is carbon dioxide?
Carbon dioxide (chemical formula CO2) is a naturally occurring chemical compound composed of two oxygen atoms covalently bonded to a single carbon atom. It is a gas at standard temperature and pressure and exists in Earth's atmosphere in this state, as a trace gas at a concentration of 0.039% by volume.
In what two places do convection currents form when the Sun heats Earth?
Convection currents form in the atmosphere and oceans when the Sun heats the Earth. As the air and water near the Earth's surface warm up, they become less dense and rise, creating a circulation pattern where cooler air or water replaces them.
