Question 7 (1 point)
Sammy feels an ocean breeze as he plays volleyball at the beach. Why do ocean winds or sea breezes blow toward shore during the day?
a
Ocean air is less dense, so it moves in to replace the air over the land.
b
Air over the beach heats up, rises and is replaced by ocean air.
c
Earth’s rotation causes air to blow toward land
d
The energy of the ocean storms push air toward shore.
Question 8 (3 points)
Describe the 3 factors that impact atmospheric pressure?
Answers
Option B is correct q no 1
Answer:
1 Ans-Air in the atmosphere moves around the world in a pattern called global atmospheric circulation. ... This pattern, called atmospheric circulation, is caused because the Sun heats the Earth more at the equator than at the poles. It's also affected by the spin of the Earth. In the tropics, near the equator, warm air rises
2 Ans-Along 30° N and 30° S are found the high-pressure areas known as the subtropical highs. Further pole wards along 60° N and 60° S, the low-pressure belts are termed as the sub polar lows. Near the poles the pressure is high and it is known as the polar high. These pressure belts are not permanent in nature.
3 Ans-A low-pressure area, low area or low is a region where the air pressure is lower than that of surrounding locations. Low-pressure systems form under areas of wind divergence that occur in the upper levels of the atmosphere. The formation process of a low-pressure area is known as cyclogenesis
4 Ans-Explanation: Usually when we talk about uneven heating of the Earth's surface we are discussing convection. The uneven heating results in some of the atmosphere to be warmer than other parts and changes in volume and pressure which result in updrafts and can cause thunderstorms and other violent weather.
5 Ans-The trade winds or easterlies are the permanent east-to-west prevailing winds that flow in the Earth's equatorial region (between 30°N and 30°S latitudes).
6 Ans-Jet streams are fast flowing, narrow, meandering air currents in the atmospheres of some planets, including Earth. On Earth, the main jet streams are located near the altitude of the tropopause and are westerly winds (flowing west to east). Their paths typically have a meandering shape.
7 Ans-Sammy feels an ocean breeze as he plays volleyball at the beach. Why do ocean winds or sea breezes blow toward shore during the day? Earth's rotation causes air to blow toward land
8 Ans-The 3 main factors that affect barometric (air) pressure are: Temperature of air. Altitude or Elevation. Moisture
