What Are Some Possible Influences Of Ocean Currents On Glaciation??
What are some possible influences of ocean currents on glaciation? Cold currents can cool the land allowing glaciers to form if there is sufficient precipitation. Cold currents can inhibit the growth of glaciers because they put less moisture into the atmosphere.
What factors affect glaciation?
- Latitude and the Seasonal Temperature.
- Angle of Solar Radiation and Temperature.
- The Seasons.
- Water Influence on Temperature.
- Ocean Currents.
- Elevation.
What happens when a glacier encounters the sea or lake?
What happens when a glacier encounters the sea or a lake? Large blocks of ice collapse off the front of the glacier and become icebergs. … As snowflakes are buried and compressed eventually becoming crystalline ice.
What is a primary reason an increase in glaciers on land would cause sea level to fall?
The land flexes upward due to isostatic rebound. What is a primary reason an increase in glaciers on land would cause sea level to fall? the erosive effects of waves.
What evidence is left behind glaciers?
The most apparent evidence is of course the glacial drift itself. Glacial drift refers to the rock material ground up and transported by a glacier and deposited by or from the ice (till) or in water derived from the melting of ice (outwash or lake sediment).
How does precession affect glaciation?
So when the precessional cycle causes a series of cooler summers in the Southern Hemisphere sea ice can expand dramatically because there’s less summer melting. The precession cycle can influence global climate because the Southern Hemisphere has a higher capacity of sea ice growth.
What causes glaciation quizlet?
A slowly moving mass or river of ice formed by the accumulation and compaction of snow on mountains or near the poles. Glaciers are made up of fallen snow that over many years compresses into large thickened ice masses.
What would occur if all of the ice on Greenland and Antarctica melted?
If all the ice covering Antarctica Greenland and in mountain glaciers around the world were to melt sea level would rise about 70 meters (230 feet). The ocean would cover all the coastal cities. And land area would shrink significantly.
Which of the following would cause sea level to rise?
The two major causes of global sea level rise are thermal expansion caused by warming of the ocean (since water expands as it warms) and increased melting of land-based ice such as glaciers and ice sheets.
What are some hazards that exist along coastlines?
Some of the hazards include movement of barrier islands sea level rise hurricanes nor’easters earthquakes flooding erosion pollution and human development along the coast.
What are some possible influences of ocean currents on glaciation quizlet?
What are some possible influences of ocean currents on glaciation? Cold currents can cool the land allowing glaciers to form if there is sufficient precipitation. Cold currents can inhibit the growth of glaciers because they put less moisture into the atmosphere.
What is a primary reason that an increase in glaciers on land would cause sea level to fall quizlet?
What is a primary reason that an increase in glaciers on land would cause sea level to fall? Glaciers tie up large volumes of water that would otherwise be in the sea.
How do glaciers contribute to sea level rise?
How much are glaciers contributing to sea-level rise? Melting ice sheets in Greenland and the Antarctic as well as ice melt from glaciers all over the world are causing sea levels to rise.
How does glaciation affect the landscape?
How do glaciers cause deposition?
What physical effects do glaciers leave on the land?
What caused the last glaciation?
When less sunlight reaches the northern latitudes temperatures drop and more water freezes into ice starting an ice age. When more sunlight reaches the northern latitudes temperatures rise ice sheets melt and the ice age ends.
What are the two primary Proposed causes of ice ages and glaciation in your textbook?
What causes ice-ages? Fluctuations in the amount of insolation (incoming solar radiation) are the most likely cause of large-scale changes in Earth’s climate during the Quaternary. In other words variations in the intensity and timing of heat from the sun are the most likely cause of the glacial/interglacial cycles.
How does glaciation affect the amount of solar energy reaching the earth?
These oscillations from more elliptic to less elliptic are of prime importance to glaciation in that it alters the distance from the Earth to the Sun thus changing the distance the Sun’s short wave radiation must travel to reach Earth subsequently reducing or increasing the amount of radiation received at the …
What are the two primary Proposed causes of ice ages and glaciation quizlet?
Ice ages could be caused by changes in the Earth’s orbit in the tilt of the Earth’s axis by plate tectonics volcanic eruptions or asteroid impacts.
What are two things that can cause an ice age?
In general it is felt that ice ages are caused by a chain reaction of positive feedbacks triggered by periodic changes in the Earth’s orbit around the Sun. These feedbacks involving the spread of ice and the release of greenhouse gases work in reverse to warm the Earth up again when the orbital cycle shifts back.
What are ice ages quizlet?
An ice age is a long period of climatic cooling during which glaciers advance and retreat. … According to the Milankovitch theory glacial periods are caused by three different changes in Earth’s movement relative to the sun.
What would occur if all of the ice on Greenland and Antarctica melted quizlet?
What sea level rise would occur if all of Greenland’s ice sheet melted? … ice streams and glaciers increase in speed and ice shelves are breaking off.
What would happen to global sea levels if all the ice in West Antarctica melts quizlet?
What would happen to global sea levels if all the ice in West Antarctica melts? Sea level would rise by a significant amount. … If you do not remember the approximate size of this rise the volume of ice is 3 000 000 km3 and the surface area of the world’s ocean is 361 000 000 km2.
Why did the Greenland Ice Sheet keep melting from 2008 to 2017 even though ocean warming paused?
With the new data we can now be certain that the Greenland ice sheet is melting from below by the warming ocean. … Together these glaciers caused nearly half of Greenland’s ice loss between 1992 and 2017. This is because the warm and salty water melted the ice from underneath and caused the ice to flow faster.
Which is the main reason that sea levels have risen recently?
Global sea levels are rising as a result of human-caused global warming with recent rates being unprecedented over the past 2 000-plus years. Sea level rise is caused primarily by two factors related to global warming: the added water from melting ice sheets and glaciers and the expansion of seawater as it warms.
What factors are currently causing the sea level to rise quizlet?
Sea level rise is caused primarily by two factors related to global warming: the added water from melting ice sheets and glaciers and the expansion of sea water as it warms.
What are the 3 causes of sea level rise?
What are different hazardous effects of coastal processes?
The main threats associated with these hazards are storm surge high winds heavy rain and flooding as well as tornadoes. Winter storms can produce rough lake conditions coastal flooding and beach erosion.
What factors influence the shape of the coast?
- The rock type/geology (see map below). …
- The fetch of the wave and the strength of the wind. …
- The angle of the slope – steep slopes erode more violently and frequently.
- Weather conditions – freezing temperatures and heavy rain increase weathering and the rate of erosion.
