glacial advance multiple choice a.causes earth's albedo to decrease and causes global sea level to rise. b.causes earth's albedo to increase.
c. causes global sea level rise.
d. causes earth's albedo to decrease.
Glacial advance refers to the forward movement of glaciers and ice sheets. It happens when snow accumulates and compresses to create ice. The correct option is C.
This ice then flows down the valley under the influence of gravity and builds up as more snow is added from above. As glaciers advance, they can impact the climate in a variety of ways.One of the effects of glacial advance is that it causes the Earth's albedo to decrease. Albedo refers to the reflectivity of the Earth's surface. When ice sheets advance, they cover the Earth's surface with a highly reflective layer of snow and ice. This reflects more sunlight back into space, which can cause the Earth's temperature to cool. However, as the ice sheets continue to grow, they can absorb more sunlight, which causes the Earth's albedo to decrease. This, in turn, can cause the Earth's temperature to warm.The second effect of glacial advance is that it can cause global sea levels to rise. As glaciers and ice sheets melt, the water they release flows into the oceans, causing sea levels to rise. This can have significant impacts on coastal communities, leading to increased flooding and erosion. Additionally, the release of freshwater into the oceans can impact ocean circulation patterns and lead to changes in climate.Finally, it's worth noting that glacial advance can also cause changes in the Earth's atmospheric circulation. As temperatures change and ice sheets grow, patterns of atmospheric pressure can shift, leading to changes in wind and precipitation patterns. This, in turn, can have significant impacts on weather patterns and regional climates. In conclusion, glacial advance can cause the Earth's albedo to decrease, cause global sea levels to rise, and impact atmospheric circulation patterns.

Plate tectonics is the most important for maintaining a stable climate on Earth over the time it took for large organisms to evolve. Plate tectonics is the movement of the Earth's lithosphere (outermost layer) which causes the formation of mountains, earthquakes, and volcanic activity. The process of plate tectonics helps regulate the carbon cycle, which is important for maintaining a stable climate. When tectonic plates move, they cause the release of carbon dioxide from the Earth's mantle, which is then trapped in rocks through a process called weathering. This process helps remove excess carbon dioxide from the atmosphere, which prevents the greenhouse effect and helps keep the Earth's temperature stable.

Considering the urban carbon, nitrogen, and phosphorus cycles, briefly describe two positive impacts of trees on the cycles and two potential negative impacts on the cycles (i.e.,
potential tradeoffs).
Trees play a crucial role in urban planning by positively influencing the carbon, nitrogen, and phosphorus cycles in cities. Here are two positive impacts and two potential tradeoffs associated with trees in these cycles:
Positive impacts:
1. Carbon sequestration: Trees absorb carbon dioxide (CO2) during photosynthesis, acting as carbon sinks. They store carbon in their biomass and help mitigate climate change by reducing greenhouse gas concentrations in the atmosphere.
2. Nutrient cycling and retention:Trees contribute to the nitrogen and phosphorus cycles by taking up and cycling these nutrients. They absorb nitrogen and phosphorus from the soil, preventing excessive nutrient runoff into water bodies and promoting nutrient recycling within ecosystems.
Potential tradeoffs:
1.Increased nutrient leaching: In certain cases, tree canopies can intercept rainfall and create a localized dry area beneath them, leading to reduced nutrient uptake by the roots and potential nutrient leaching. This can result in the loss of nitrogen and phosphorus from the urban ecosystem, impacting water quality.
2. Altered carbon storage in soils: The presence of trees can lead to changes in soil carbon storage. While trees contribute to aboveground carbon sequestration, they can also alter soil organic matter decomposition rates. Changes in decomposition can affect the release of carbon dioxide from the soil, potentially altering the overall carbon balance in urban areas.

Please identify and explain the processes responsible for the genesis of this glacial feature. Is this landform erosional or depositional? (you can include drawings). (4 points)
The glacial feature in question is a cirque, which is a bowl-shaped depression in a mountain or hillside that is typically formed by glacial erosion. Cirques are erosional landforms, created as glaciers carve away the surrounding rock and sediment through a process called plucking. This process occurs when the ice freezes onto loose rock and sediment, and as the glacier moves, it pulls these materials away from the mountain, forming a bowl-shaped depression.
The process of cirque formation begins with the accumulation of snow in a mountainous region, which over time becomes compacted into glacial ice. As the glacier flows down the mountain, it erodes the surrounding rock through a combination of plucking, abrasion, and melting. Over time, this process creates a bowl-shaped depression that is deeper at its center and shallower at its edges.
The steep walls of a cirque are often the result of glacial plucking, where ice freezes onto the rock surface and then pulls it away as the glacier moves. This can create overhanging walls that can be quite dramatic. Cirques are typically found at higher elevations, where snow and ice can accumulate to form glaciers.

Heat from basaltic magma partially melting overlying crust
C. Friction along the crust in a convergent plate boundary
D.
Crystal settling during magmatic differentiation
The process thought to generate most felsic magmas, such as those found at Yellowstone, is heat from basaltic magma partially melting overlying crust.
This process is known as partial melting of the crust. When hot basaltic magma rises towards the Earth's surface, it can transfer heat to the surrounding crust. The intense heat causes partial melting of the crust, leading to the formation of felsic magmas. These felsic magmas are enriched in silica and have a higher viscosity compared to basaltic magmas.
While other processes like decompression melting in a continental rift zone, friction along the crust in a convergent plate boundary, and crystal settling during magmatic differentiation can contribute to magma formation and differentiation, the partial melting of the crust is considered the primary process for generating felsic magmas at Yellowstone.

The diagram below shows a solar system model. Picture shows Earth at the center with seven circular orbits around it. The first orbit around Earth has the moon and the fourth orbit around Earth has the sun. All the other orbits have small planets on small circular orbits. The model was proposed by Claudius Ptolemy Nicolaus Copernicus Johannes Kepler Sir Isaac Newton
The observation that this geocentric model of the solar system help to explain is option C: retrograde motion.
What is retrograde motion?The term "retrograde motion" is one that is seen as the perceived reverse or westerly movement of planets observed during nighttime. During the period when the geocentric model of the solar system was widely accepted, with Earth as its focal point, the unusual occurrence of retrograde motion was a puzzling phenomenon that required further analysis.
The geocentric model states that in a flawless circular motion, all celestial entities such as stars, the Sun, planets, and the Moon orbited around the Earth. Observations made by ancient astronomers showed that specific planets, including Jupiter, Mars, and Saturn, occasionally demonstrated retrograde motion.
