Answer:
c. is the most common atmospheric gas.
Explanation:
Nitrogen gas is the most abundant gas in the atmosphere. This gas is about 78% of total amount of gas within the atmosphere.
- The earth's atmosphere is a mixture of many gases.
- Nitrogen is the most dominant of all the gases.
- Oxygen is about 21% and closely follows Nitrogen in terms of the volume it occupies.
- Several processes living and non-living utilizes nitrogen
Metamorphic rocks that show layers of dark minerals alternating with layers of light minerals are classified as foliated.
<h3><u>Difference between urban and rural areas:
</u></h3>
<u>Urban areas:
</u>
- These areas are large and almost planned settlements fabricated through a process called urbanization.
- Large and diverse populations reside in these areas. The allocation of natural and man made resources is also properly planned in urban areas. Industrial settlements are more in number than agricultural settlements.
<u>Rural areas:
</u>
- These areas are comparatively smaller in size and lack proper planning in settlement.
- The use of natural resources is often unsupervised. These areas also lack modern facilities and amenities.
- The population of these areas is substantially low and most of the population depends on agriculture and allied activities to make a living.
Answer:
They can blow from one direction in the morning, and from the opposite direction in the evening, and they are caused from differences in temperature of the land and the ocean.
Explanation:
The coastal breezes are breezes that occur near the coastlines. The general rule for the direction of the wind implies here as well as in any other place in the world, the wind blows from an area with higher air pressure toward an area with lower air pressure. When it comes to the coastal regions, because they have two contrasting landscapes, the wind changes direction during the day.
The land and the water have different properties, with the land heating up much faster and cooling off much faster, while the water heats and cools off slowly. This leads to larger oscillations in the temperature on land and with it larger oscillations in air pressure, while the temperature oscillations in the water are small and with it, the air pressure has much lower oscillation. When the land heats up, the wind blows from the ocean toward land because the air pressure is higher above the water, but when the land is cooler, the wind blows from the land toward the ocean because the air pressure is higher above the land.
