The \( 30 \% \) extinction rate is not an effect on humans from climate change.
Correct option is D. \( 30 \% \) extinction rate
Climate change has had a tremendous impact on the world's ecosystems and human life, but it is not responsible for a \( 30 \% \) extinction rate. Warmer temperatures have caused numerous changes in our environment, including human refugees, wide spread famine, and the collapse of global industries.
Human refugees are people who have been displaced from their homes due to extreme weather conditions and changes in their local climate, such as flooding, drought, and sea level rise. Wide spread famine is also the result of extreme weather events, which disrupt food production and access to basic necessities.
Collapsed global industries are the result of the economic disruption caused by resource scarcity, particularly in coastal communities that rely on fisheries or tourism for their livelihoods. Climate change has far reaching effects on the health of all living things, but it does not appear to be directly linked to a \( 30 \% \) extinction rate of any species.

Describe how a daytime sea breeze may form in a coastal region
and describe the associated wind pattern. Explain how and why the
wind pattern changes at night.
A daytime sea breeze forms in coastal regions due to differential heating between the land and sea surfaces. During the day, the land heats up more quickly than the sea due to its lower heat capacity.
As a result, the air above the land becomes warmer and less dense, leading to a lower atmospheric pressure compared to the air over the sea. This pressure gradient initiates the sea breeze. The sea breeze is characterized by wind blowing from the cooler sea towards the warmer land. As the cooler air from the sea replaces the warmer air over the land, it brings a refreshing and cooler breeze inland. The sea breeze typically reaches its maximum strength in the afternoon.
At night, the wind pattern undergoes a reversal due to the radiative cooling of the land. The land surface cools faster than the sea, causing the air over the land to become cooler and denser. This creates a pressure gradient that drives a land breeze, with the wind direction reversing from the sea towards the land. The land breeze is typically weaker and less pronounced compared to the daytime sea breeze.
Overall, the daytime sea breeze and nighttime land breeze are diurnal patterns driven by the differential heating and cooling of the land and sea surfaces, respectively.

The description of the tectonic setting needs to include the plate names, types of the lithosphere at the boundary, and specific boundary type responsible for forming the volcanoes. Also, be sure to explain how and where melting occurs that generates the magma that fuels the volcanoe
The Cascade Volcanoes are located along the Cascadia Subduction Zone, a convergent plate boundary between the Juan de Fuca and North American plates.
The Juan de Fuca plate is an oceanic plate composed of dense basaltic lithosphere, while the North American plate is a continental plate composed of lighter granitic lithosphere. As the Juan de Fuca plate subducts beneath the North American plate, the denser oceanic lithosphere is forced down into the mantle, creating a zone of intense friction and melting.
This melting generates magma that rises to the surface, fueling the Cascade Volcanoes. The Cascadia Subduction Zone is a type of convergent boundary known as a subduction zone, where one plate is forced beneath another. This type of boundary is responsible for the formation of the Cascade Volcanoes, as well as other volcanoes located along the Pacific Ring of Fire.

If the earth rotation increases up to 1.5 times its current speed, we should expect that days would be shorter. This is because the earth would be spinning faster, meaning that it would take less time for the earth to make one full rotation.
This would result in shorter days, as the same amount of time would be spent in a day, but the earth would have rotated further. Additionally, the number of days during one revolution around the sun would increase. This is because the earth would be spinning faster, meaning that it would take less time for the earth to make one full revolution around the sun.
However, the number of hours needed to complete a full revolution around the sun would remain the same as today.

Explain how the following characteristies differs in rocks formed close to steep mountain slopes and those within the beaches. i) Size. ii) Sorting. iii) Roundness
Size: Boulders near steep hillsides tend to be larger than those on the coast. Geological processes such as weathering, erosion, and mass transfer near mountain slopes cause larger rock fragments to collapse. These fragments accumulate to form coarse-grained rocks. Coastal rocks, on the other hand, are constantly under the action of waves, and large rocks tend to break into smaller particles.
Sorting: Rocks that form near steep hillsides are usually poorly fractional, implying the presence of a wide range of sizes within rock groups. The dynamic nature of mountain slopes, such as rockfalls and landslides, mixes particles of different sizes. In contrast, coastal rocks often exhibit better sorting because waves act continuously, selectively transporting and sorting particles based on size and weight. This makes the size of the particles within the beach rock relatively uniform.
Roundness: Rocks near steep hillsides are generally jagged or have sharp edges. Intense mechanical weathering processes near mountain slopes break rocks into irregular, rough-surfaced fragments. In contrast, coastal rocks are worn and carried by waves, thus smoothing and rounding their edges. Over time, due to continuous wear and collision with other particles, wave action shapes beach rocks into a more rounded shape.

Describe how clouds affect the solar radiation balance of the atmosphere. Differentiate between high-altitude thin clouds and low-altitude dense white clouds.
Use these terms:
1. Albedo
2. Greenhouse effect
Clouds affect the solar radiation balance of the atmosphere by reflecting and absorbing incoming solar radiation. High-altitude thin clouds, such as cirrus clouds, are composed of ice crystals and are highly reflective, meaning they have a high albedo.
This means that they reflect a large portion of the incoming solar radiation back into space, cooling the atmosphere. Low-altitude dense white clouds, such as cumulus clouds, are composed of water droplets and are less reflective, meaning they have a lower albedo.
This means that they absorb a large portion of the incoming solar radiation, trapping it in the atmosphere and contributing to the greenhouse effect. This causes the atmosphere to warm. In summary, clouds can both cool and warm the atmosphere depending on their composition and altitude.
