What three characteristics of earth shape and motion affect weather?

The three characteristics of Earth's shape and motion that affect weather are its spherical shape, axial tilt, and rotation. The spherical shape leads to uneven heating from the sun, creating temperature gradients that drive wind and ocean currents. The axial tilt causes seasonal variations in sunlight, influencing temperature and precipitation patterns. Lastly, Earth's rotation affects atmospheric circulation and the Coriolis effect, which influences the direction of winds and ocean currents, further shaping weather systems.


What are 3 natural physical system?

Three examples of natural physical systems are ecosystems, weather systems, and geological systems. Ecosystems involve the interactions between living organisms and their physical environment, influencing biodiversity and energy flow. Weather systems encompass atmospheric conditions, including temperature, humidity, and wind patterns, which affect climate and precipitation. Geological systems refer to the processes shaping the Earth's crust, such as plate tectonics, erosion, and sedimentation.

How many wind and pressure systems are contained within Earth's atmosphere?

There are generally three main wind systems in Earth's atmosphere: the polar easterlies, the westerlies, and the trade winds. There are also three main pressure systems: high-pressure systems, low-pressure systems, and mid-latitude cyclones. These wind and pressure systems interact to create global weather patterns.
