Why are the Great Lakes important to both the United States and Canada?
The great lakes are important to both the United States and Canada because:
Tens of millions of Americans and Canadians get their water from them. The economies of both nations rely on the great lakes to support activities such as industry, farming, transportation, tourism, recreation, and energy production.
The many indigenous peoples in the area place tremendous cultural value on the health of the great lakes. Some tributaries of the great lakes were utilized for years to dispose of waste and other byproducts of economic growth as well as deteriorating infrastructure in order to accommodate these byproducts.
Industrial waste was commonly buried or dumped into wetlands and nearshore seas, while liquid waste was sometimes poured straight into streams and lakes. Solid garbage was frequently deposited into marshes.

How can you protect the coastline using hard and soft engineering techniques
Hard engineering is a coastal management technique used to protect coasts, by absorbing the energy of waves, preventing erosion and flooding. They are highly visible man-made structures used to stop or disrupt natural processes
Explanation:Soft engineering is where the natural environment is used to help reduce coastal erosion and river flooding. At the coast, soft engineering is where a beach is used to absorb wave energy and reduce erosion. Through hard coastal protection strategies, we try to work against natural interactions in order to protect certain eras. Soft coastal protection strategies are methods to secure and/or restore coastal lines through a body of sand. The other option, soft Engineering, involves using natural defences to protect the coastline.

what process that brings heat from the lower mantle toward the crust?(1 point) responses compression compression conduction conduction cementation cementation convection
Mantle convection transports heat from the mantle's depths to the surface, where the heat is released to create the oceanic crust-creating magmas.
What is Mantle convection?
Convection, a thermally driven process whereby deep heating causes material to expand and become less dense, leading it to rise while being replaced by complementary cool material that sinks, is the primary method of heat transport in the Earth's mantle. Because the material that rises releases heat as it rises and cools, and the material that sinks acquires heat only to eventually rise again, this cycle of heat transfer from depth to the surface is particularly effective. Convection, together with conduction, radiation, and advection, is the most significant mechanism by which the Earth loses heat. However, the plate tectonic cycle combines a lot of these mechanisms.
Mantle convection transports heat from the mantle's depths to the surface, where the heat is released to create the oceanic crust-creating magmas.
Active hydrothermal circulation and heat loss occur along the midocean ridge axis, creating vents like black smoker chimneys. The crust and lithosphere eventually sink to a depth of 1.5–2.5 miles (2.5–4.0 km) below sea level as they move away from the midocean ridges and cool through conduction. The primary process of plate tectonics is consequently heat loss by mantle convection, and moving plates can be viewed as the conductively cooling boundary layer for large-scale mantle convection systems.
Convection heat is produced by the decay of radioactive elements, including potassium 40, uranium 235, and thorium 232. It is also produced by leftover heat from the Earth's early formation, including iodine 129, leftover heat from meteorite and asteroid impacts, and leftover heat from the Earth's core formation.
The Earth has been cooling via convection ever since the mantle of the planet was at least partially molten early in its history. Although it is difficult to gauge how much the mantle has cooled through time, reliable estimates indicate that the mantle may have been several hundred degrees hotter in the earlier Archean.

The east coast of United States is at high risk because of the presence of barrier islands, low elevation lands and gentle slopes of the coast.
The west Antarctic Ice sheet is collapsing at a faster rate due to the effect of Global Warming. This causes the ice to melt and an increase in the water level of the oceans and other water bodies. The east coast of the United States mainly comprises of the Atlantic Ocean and with the Atlantic Ice sheet melting it is the most vulnerable coast. The sea level if risen to an altitude greater than what is elevated then the people of the east coast will suffer. The presence of islands within the east coast which are called the barren islands provide the seawater a path to travel in the cities. Also, the area of the east coast is at a lower elevation, and this will provide no blockage to the rising seawater from flooding the cities. The slopes towards the coast are also gentle and not steep which will pave way for the seawater. All these reasons make the east coast most vulnerable.

Which diagram shows an oceanic-oceanic convergent boundary? describe what occurs at this type of plate boundary
Part C of the following diagram shows an oceanic- oceanic convergent boundaries.
What are Convergent boundaries?A convergent boundary is a spot-on Earth where two or more lithospheric plates collide. One plate will always slide under another during subduction. Ocean-ocean, ocean-continent, and continent-continent are the three different forms of convergent boundaries.
What is Oceanic-Oceanic Convergent boundaries?Oceanic-continental convergent borders are created when tectonic plates with primarily oceanic lithosphere collide with plates with primarily continental lithosphere.
Compared to the continental lithosphere, the crust is denser because it has more minerals rich in iron and magnesium. The oceanic lithosphere plate will buckle beneath the continental plate and plunge into the warm asthenosphere when these two very distinct plates intersect. Subduction is the term for this action. The melting occurs as the subducting plate is pushed further into the mantle. This generates magma, which rises and erupts. This creates an island arc, a line of volcanoes. Examples of island arcs include Japan, Indonesia, the Philippines, and the Aleutian Islands of Alaska.

What is the connection to seasonal cycles?
During the 10th month of the year i.e. September, the extent of the Arctic sea ice is at its lowest. During the summers and spring, the Earth's surface receives maximum insolation. As a result of this, the ocean surface receives insolation and gradually warms up. It is to be understood that on account of the high specific capacity of water, the water cools and warms up slowly. Hence, there is a time lag between the duration of insolation and the consequential appearance in the increase of the temperature of the oceanic water.The ocean bodies begin to lose their buoyancy after summer ends, and this continues to be the period when there is the least amount of ice.
