The three models below show the same amount of sunlight striking different parts of Earth's surface at different angles. Select the model that shows the part of Earth's surface that would heat up the least.
O A
O B
O C
To determine which model shows the part of Earth's surface that would heat up the least, we need to consider the angle at which sunlight strikes the surface. A smaller angle means that the sunlight is spread out over a larger area, resulting in less concentrated heat.
Looking at the models, the model with the smallest angle of sunlight striking the surface would heat up the least. The representation of this model is not provided in the question, as it only mentions models A, B, and C.
Panel A shows the Earth at night. In this panel, the arrows represent the movement of cold air from the poles towards the equator. This cold air sinks as it approaches the equator, and it helps to drive the Earth's ocean currents.
Panel B shows the Earth during the day. In this panel, the arrows represent the movement of warm air from the equator towards the poles. This warm air rises as it approaches the poles, and it helps to create precipitation.
Panel C shows the Earth at night again. This panel is similar to Panel A, but it also shows the movement of air within the troposphere, the lowest layer of the Earth's atmosphere.
Based on the provided information, panels A and C show the Earth at night. In Panel A, the movement of cold air from the poles towards the equator is depicted, which helps drive the Earth's ocean currents. This sinking cold air does not contribute to heating up the Earth's surface significantly.
Therefore, Panel A would show the part of Earth's surface that would heat up the least among the given options.
