Evidence of Earth's Rotation (Star Trails, Coriolis, Foucault)

The diagram below represents a Foucault pendulum that is swinging back and forth. Which diagram best represents the change in the motion of a Foucault pendulum that provides evidence of Earth's rotation?

• Different direction of swing

• Longer length of swing

• Swinging stops

• Begins to spin

Base your answer to the following question on the diagram below. The diagram represents the Earth at a position in orbit around the Sun, the Sun's rays at solar noon, and the direction to Polaris. Letters A through D represent positions on the Earth's surface. A projectile is launched from a point near the North Pole toward the Equator. Which diagram best represents the apparent path of the projectile, as viewed from the Earth?

The best evidence that Earth spins on its axis is provided by

• variations in atmospheric density

• apparent shifts in the swing of a Foucault pendulum

• changes in the position of sunspots on the Sun

• eclipses of the Moon

The diagram below represents an activity in which an eye dropper was used to place a drop of water on a spinning globe. Instead of flowing due south toward the target point, the drop followed a curved path and missed the target. The actual path results from

• the tilt of the globe's axis

• the Coriolis effect

• the globe's revolution

• dynamic equilibrium

A Foucault pendulum appears to change its direction of swing over a period of several hours because of Earth’s

• rotation

• revolution

• tilted axis

• gravity

The apparent change in direction of a swinging Foucault pendulum is the result of the

• A) rotation of Earth

• B) revolution of Earth

• C) tilt of Earth's axis

• D) shape of Earth's orbit

In the Northern Hemisphere, planetary winds deflect to the

• right, due to the Coriolis effect

• right, due to the Doppler effect

• left, due to the Coriolis effect

• left, due to the Doppler effect

According to Foucault, this change in direction of swing was caused by the

• Moon's rotation on its axis

• Moon's revolution around the Earth

• Earth's rotation on its axis

• Earth's revolution around the Sun
