How does stable air differ from unstable air? What weather conditions would lead you to believe that air is unstable?
Stable air differ from Unstable air and the weather conditions would lead you to believe that air is unstable
When compared to unstable air, stable air is more resistant to upward motion. When stable air is made to rise, it often forms thin clouds that only sometimes provide light to moderate precipitation. On the other hand, when unstable air rises, clouds are frequently towering and heavy precipitation is possible.
When the air in a mass of air is warmer and/or more humid than the air above it, the air is said to be unstable in the lowest levels of the mass. The air will rise as a result because the air parcel is warmer than the air around it at that time. The weather can shift abruptly and become violent in an unstable setting.

A conical circus tent has a 20 ft central pole that supports it. The slant height of the tent is 26 ft long. Explain how to find the angle the tent pole makes with the sides of the tent.
A diagram of a cone. The length and height of a cone are 26 feet and 20 feet.
The value of the missing angle is the ratio of the length of the central pole to the length of the side of the tent, which is 0.77. Applying arccosine, we find that the angle the tent pole makes with the sides of the tent is 39.6°.
How to find the angle the tent pole makes?In order to determine the angle the tent pole makes, we would apply the law of cosine because the central pole forms a right-angle triangle with the floor of the tent:
cos(θ) = Adj/Hyp
Where:
Adj is the adjacent side of a right-angled triangle.Hyp is the hypotenuse of a right-angled triangle.θ is the angle.Substituting the parameters into the formula, we have;
cos(θ) = Adj/Hyp
cos(θ) = 20/26
cos(θ) = 0.77
θ = cos⁻¹(0.77)
Angle, θ = 39.6°.
In conclusion, we can infer and logically deduce that the value of the missing angle is the ratio of the length of the central pole (adjacent) to the length of the side of the tent (hypotenuse), which is 0.77. Applying arccosine, we find that the angle the tent pole makes with the sides of the tent is 39.6°.

When are upper air winds fastest? anytime surface temperature gradients are weak in summer in winter these winds maintain about the same speed throughout the year.
In winter the upper air winds fastest .
Why wind speed higher in winter ?
Temperature differences between air masses lead to pressure differences and this produces wind. The winter brings higher temperature gradients especially when cold fronts move in from polar regions and this causes wind speeds that are higher than normal.
Since the wind direction at the higher level is parallel to the isobars and its speed is greater than surface wind this transfer causes the surface wind to veer and increase in speed.

What do you notice about the location of the plate boundaries and the location of the earthquakes?
The majority of earthquakes happen at the points where the plates converge. Earthquake sites and the kind of ruptures they cause to aid in the identification of plate borders by geologists. Spreading zones, transform faults, and subduction zones are the three different kinds of plate boundaries.
How does the location of earthquakes relate to the location of plate margins?
Along fault lines, which are crevices in the Earth's crust where tectonic plates collide, earthquakes happen. They happen when plates are clashing, spreading, subducting, or slipping. Pressure rises as the plates become trapped as they grind against one another. Finally, the plates become loose due to the intense pressure between them.
What is the relationship between plate boundaries and earthquake size?
Earthquakes at divergent plate borders typically have modest and shallow tremors. Small yet violent earthquakes occur at plate borders. Deep and violent earthquakes occur near convergent plate boundaries, where two continental plates clash.

Why is the mesosphere colder than the thermosphere, even though it's closer to earth?
Answer:
Mesosphere lies in between 50 to 80 km above the earth surface and due to low density gases escape easily and hence it is colder.
Explanation:
Mesosphere has the capacity to not absorb the infrared radiation that's why the gases reflected from the earth surface escape the layer of mesopause and goes inside the thermosphere.
In the thermosphere, even the minute atoms of gases ca be absorbed by the layer which increases the air temperature and the air rises up hence making thermosphere as the hottest layer in the atmosphere.

Why are western boundary currents intensified compared to eastern boundary currents?
One reason for the westward boundary intensification of boundary currents has to do with the intensification of the Coriolis effect with latitude. The Coriolis effect is stronger at western latitudes than at trade wind latitudes.
The Kuroshio is the western boundary current of the subtropical gyre in the North Pacific and requires comparison with its Atlantic counterpart, the Gulf Stream.
The Western Boundary Current is a strong, narrow current confined to the western side of the basin. In the North Atlantic, the Gulf Stream is the western boundary current of the anticyclonic subtropical gyre, and the North Atlantic Current (NAC) is its northeastern extension (Arhan, 1990; Rossby, 1996).
