What causes two distinct pressure zones between equator and the poles?
The Earth's rotation turns the polar high pressure systems westward as they move from the poles (westerlies), and the subtropical high pressure systems eastward as they move toward the equator (tropical easterlies).
Explain why Geostrophic wind is not possible at the equator?
Geostrophic wind is not possible at the equator because the Coriolis force is negligible at the equator due to the Earth's rotation, resulting in a weak pressure gradient force dominating. This weak Coriolis force prevents the balance between pressure gradient force and Coriolis force required for geostrophic winds.
Why when a long range cannon is fired toward the equator from a northern latitude it lands west in its intended longitude?
This is due to the Earth's rotation causing a Coriolis effect, which deflects the trajectory of moving objects. As the cannonball travels towards the equator from a northern latitude, it retains some of the eastward velocity from the Earth's rotation, causing it to land west of its intended longitude.
What happens if a cyclone crosses the equator?
This is impossible. A cyclone cannot cross the equator. The reason why this cannot happen is because the Coriolis Force reduces to almost nothing at the equator. The effect on a cyclone would be to cause it to dissipate.
At which location does the coriolis force have the least effect on wind?
The Coriolis effect has the least effect on winds in equatorial regions and the most effect on winds in polar regions. Coriolis effect deflects winds to the right of their initial direction in the northern hemisphere and left of their initial direction in the southern hemisphere.
What causes two distinct pressure zones between equator and the poles?
The Earth's rotation turns the polar high pressure systems westward as they move from the poles (westerlies), and the subtropical high pressure systems eastward as they move toward the equator (tropical easterlies).
Why is the Coriolis effect zero at the equator?
The Coriolis effect is zero at the equator because the rotation of the Earth is perpendicular to the direction of motion at the equator, resulting in no deflection of moving objects.
As a result of the Coriolis effect an air mass moving from the equator toward the North Pole will?
Turn towards the right
Explain why Geostrophic wind is not possible at the equator?
Geostrophic wind is not possible at the equator because the Coriolis force is negligible at the equator due to the Earth's rotation, resulting in a weak pressure gradient force dominating. This weak Coriolis force prevents the balance between pressure gradient force and Coriolis force required for geostrophic winds.
Ocean currents flow from east to west near the?
Equator due to the trade winds pushing the surface waters westward. This creates the Equatorial Counter Current, which flows eastward at the surface.
Where is Coriolis effect weakest?
The Coriolis effect is weakest at the equator because the effect is a result of the Earth's rotation, and the rotational speed is slower at the equator compared to higher latitudes. As a result, the Coriolis force is less pronounced near the equator.
Where is the Coriolis Effect the largest?
The Coriolis Effect is strongest at the poles and weakest at the equator. This is because the effect is influenced by the rotation of the Earth, and the rotational speed is greatest at the poles and slowest at the equator.
In what direction do global winds and currents flow near the equator?
westward

As the cannonball travels towards the equator from a northern latitude, it retains some of the eastward velocity from the Earth's rotation, causing it to land west of its intended longitude.
Why can't hurricanes form at the equator?
Hurricanes cannot form at the equator because the Coriolis effect, which is needed for their formation, is too weak in that region. The Coriolis effect is a force caused by the Earth's rotation that helps hurricanes spin and develop.

This is impossible. A cyclone cannot cross the equator. The reason why this cannot happen is because the Coriolis Force reduces to almost nothing at the equator. The effect on a cyclone would be to cause it to dissipate.
