Why has it been difficult to create international agreements to address climate change?
it has been difficult to create international agreements to address climate change because Addressing climate change is costly.
Climate change threatens people with food and water shortages, increased flooding, extreme heat, increased disease, and economic losses. Migrations and conflicts can occur. The World Health Organization (WHO) calls climate change the biggest threat to global health in the 21st century.
Climate change refers to long-term changes in temperature and weather patterns. These changes may be natural, for example, due to changes in the solar cycle. However, since the 19th century, human activity has been a major contributor to climate change, primarily through the burning of fossil fuels such as coal, oil, and gas. More frequent and intense droughts, storms, heat waves, rising sea levels, melting glaciers, and warming oceans can directly harm animals, destroy their habitats and wreak havoc on human lives and communities.

The vertical movements caused by loading or unloading the crust are called?
The vertical movements caused by loading or unloading the crust are called : isostatic adjustments.
crust describes the outermost shell of a terrestrial planet. Earth's crust is generally divided into older, thicker continental crust and younger, denser oceanic crust.
The crust is a thin but important zone where dry, hot rock from the deep Earth reacts with the water and oxygen of the surface, making new kinds of minerals and rocks.
The crust is deepest in mountainous areas. It can be up to 70km thick here. The continental and oceanic crusts are bonded to the mantle, which we spoke about earlier, and this forms a layer called the lithosphere. This layer is cool and rock solid.

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.
