The photographer captured an interesting scene (pictured): a crow resting on the back of an eagle. The following statement is correct: a.
Test analysis: To solve this problem, we should start with the following knowledge points: (1) To judge whether an object is moving or static, it depends on whether there is a position change between this object and the selected reference object; If the position changes, the object moves relative to the reference object; If the position is unchanged, the object is stationary relative to the reference object. (2) Light travels in a straight line in the same uniform medium. (3) The spread length of the eagle's wings exceeds 1 meter.
A, the eagle catches the crow and flies, so the ground is taken as the reference, and the crow is moving, so this option is incorrect;
B, the crow stands on the back of the flying eagle to rest. Crow and eagle are relatively static, so taking crow as reference, eagle is static, so this option is incorrect;
C, the shadow of the eagle on the ground is formed by the straight-line propagation of light, so this option is correct;
D, the eagle's wing length is greater than 1 m, so this option is incorrect.
So choose C.
