1.In a heavy snow year that sees an expansion of the zone of accumulation, what happens to the line of equilibrium?It increases in elevation.It retreats away from the toe.It remains constant.It decreases in elevation.It retreats uphill.
In a heavy snow year that sees an expansion of the zone of accumulation the line of equilibrium increases in elevation.
The area above the firn line on a glacier known as the accumulation zone is where snowfall accumulates and outpaces ablation losses. Each year, the accumulation and ablation zones are divided by the annual equilibrium line. The area of a glacier's surface, typically at higher elevations, where there is net snow accumulation that later turns into firn and glacier ice is known as the accumulation zone. The area of the glacier where snow accumulates and freezes moves outward from that point.
Equilibrium line cuts through and separates the accumulation and the factors that lead to material destruction as a result of some factors, like erosion.
The line of equilibrium rises in elevation as a result of substance deposition during a heavy snow year that sees an expansion of the zone of accumulation.

how would a decrease in the tilt of the earth's axis change the intensity of the seasons in the mid-latitudes?
A decrease in the tilt of the earth's axis changes the intensity of the seasons in the mid-latitudes when tilt affects the amount of sunlight on the Earth's surface receives throughout the year.
The tilt of the earth's axis of rotation is a condition in which the angle of the earth's axis of a planet deviates from the perpendicular drawn to its orbital plane. This kind of tilt makes the amount of sunlight that the earth receives varies at each point. This phenomenon then affects the change of seasons on earth throughout the year.
Seasonal changes will affect temperature changes. Temperature changes are affected by latitude. The temperature will be inversely proportional to latitude. The higher the latitude, the lower the temperature. The temperature will rise or warm when the latitude is at a low point.

Toxicity can refer to an impact on an organism as a whole, such as an animal, bacterium, or plant, as well as an impact on an organism's cells or organs, such the liver. By extension, the phrase may be symbolically used to indicate the negative impacts on more substantial and intricate organisations, such the family or society as a whole.

Most earthquakes occur at depths of less than 100 km. As most of the earthquakes restricted to this depth only except the deep focus earthquake at trench.
Earthquakes happen in the crust or upper mantle, which extends from the surface of the planet to a depth of around 800 kilometers (about 500 miles).The intensity of shaking at the surface from an earthquake that happens at 500 km depth is significantly less than if the same earthquake had occurred at 20 km depth because the intensity of shaking from an earthquake weakens with increasing distance from the earthquake's source.Additionally, we can learn a lot about the tectonic environment and the structure of the Earth from the depths at which earthquakes occur. The subduction zones, where plates collide and one plate is subducted beneath another, are the most obvious examples of this. We can see specifics of the structure of a subduction zone, such as how steeply it is dipping and whether the down-going plate is planar or bending, by carefully plotting the location and depth of earthquakes associated with the zone.

This coordinate system uses comparatively small zones to reach its high level of accuracy. The various zones of the State Plane Coordinate System often correspond to county boundaries (except in Alaska). A maximum typical State Plane coordinate system scaling factor is typically not greater there, at the boundary of the zone.

the arctic and antarctic sea-ice extents are both changing. one important influence on how sea ice extent changes through time (in response to global mean sea-surface temperature rise) is the surroundings. whereas the arctic sea ice is surrounded by continental crust not covered by glaciers (with the exception of greenland), the antarctic sea ice surrounds a continent that is almost entirely covered by glacial ice.
The correct answer is Arctic sea ice has declined over the past five decades, while Antarctic sea ice has increased, and then declined.
Sea ice's surface albedo decreases as it melts at the surface, increasing the amount of solar energy absorbed by the ice surface and accelerating ice melt. By creating a barrier between the cooler air above and the warmer water below, sea ice also helps to keep the air cool. Penguins, seals, and other creatures depend on the Antarctic sea ice as part of their ecosystem. Sea ice cover has decreased globally as a result of warmer air and ocean temperatures. Less ice means less heat is reflected, which leads to more severe heatwaves everywhere. But it also means more severe winters because warmer air can cause the polar jet stream, a high-pressure wind that circles the Arctic region, to drop south and bring harsh cold with it.

We humans are changing the composition of the atmosphere in many ways. Those changes will directly affect the planet’s temperature, but the resulting change in temperature will affect other things on the planet that also affect the planet’s temperature. Suppose that we could magically change the composition of the atmosphere enough to raise the temperature one degree if all other parts of the earth system were held fixed, and after the warming, we allowed the other parts of the earth system to react for a few years or decades. At the end of that time, what would be the total change in the earth’s temperature?.
The Earth's temperature will eventually be a few degrees warmer than it was before human impact, as positive feedbacks will reverse the initial change.
Even a little increase in the average yearly surface temperature of the Earth requires a substantial amount of heat energy due to the vast size and heat capacity of the seas. The roughly 2-degree Fahrenheit (1-degree Celsius) increase in global average surface temperature during the pre-industrial era (1880-1900) signifies a large gain in heat that has been stored, despite its apparent insignificance. The added heat is boosting heavy rains, producing regional and seasonal temperature extremes, reducing snow cover and sea ice, and expanding and constricting some plant and animal habitat ranges.
