Some people say the Salton Sea was an accident, and restoring it to a condition where it was a clean and popular destination is impossible or not worth the cost, its best to just let nature take its course. Write seven sentences on why you agree or disagree with that statement.

Match the following bodies of water with their description

Draggable item		Corresponding Item
Salton Sea		the largest lake in California
Lake Mono		the source of water for the Salton Sea
Lake Owens		a healthy saltwater lake in Northern California that has been restored since lawsuits stopped Los Angeles from draining the rivers that feed it
Colorado River		A dry lakebed in Northern California that has gone dry since the Los Angeles aqueduct drained the rivers that feed it

Match the following types of chemicals in the Salton Sea with description

Draggable item		Corresponding Item
Arsenic, Mercury and Lead		Naturally occurring, disease causing heavy metals that have been concentrated in the Salton sea as large amounts of water evaporated
Pesticides, Herbicides, and Fertilizer		Chemicals, some of which are no longer legal because concerns about their toxicity to people or wildlife, that have been put on fields by farmers and then drained into the Salton Sea
Sodium and Chlorine		The most common highly soluble ions that are leached from rocks into rivers and then concentrate in ocean and saline lakes with no outlet
Hydrogen Sulfide		a naturally occurring gas released by bacteria in the sediment at the bottom of the Salton Sea that sometimes get trapped or released as a large bubble of smelly gas that the wind can blow for many miles

Which of the following have contributed to large number of fish dying in the Salton Sea (several may apply)

Which of the following have reduced water levels in the Salton Sea

formed from cooling magma or lava
Marble
formed from weathered rock particles cemented together
formed from other rocks chemically and structurally altered after being exposed to heat and extreme pressure
Obsidian
Limestone
Granite
Quartzite

Igneous
Sedimentary
Metamorphic

Match the following process with its description

Draggable item		Corresponding Item
weathering		movement of rocks or soil by wind or water
caldera		break down of rocks into small particles by wind or water
subduction		pushing of one continental plate under another
continental drift		pressurized magma pushing up through the earth's crust
erosion		movement of continental plates across the surface of the world
eruption		a large volcanic crater formed from an eruption followed by the collapse of the mouth of the volcano

Describe which was true at the Aral Sea

Some people say the Salton Sea was an accident, and restoring it to a condition where it was a clean and popular destination is impossible or not worth the cost, its best to just let nature take its course. Write seven sentences on why you agree or disagree with that statement.

a healthy saltwater lake in Northern California that has been restored since lawsuits stopped Los Angeles from draining the rivers that feed it

Colorado River

A dry lakebed in Northern California that has gone dry since the Los Angeles aqueduct drained the rivers that feed it

Sodium and Chlorine

The most common highly soluble ions that are leached from rocks into rivers and then concentrate in ocean and saline lakes with no outlet

Hydrogen Sulfide

a naturally occurring gas released by bacteria in the sediment at the bottom of the Salton Sea that sometimes get trapped or released as a large bubble of smelly gas that the wind can blow for many miles

brine from desalination plants being drained into the Salton Sea

Other toxins that may not be healthy for fish

Increased salinity (Sodium chloride concentrations)  that some species cannot tolerate as water evaporates

Decreased water volume that causes there to be less carrying capacity for the number of fish that used to thrive there

Increasing the quantity of water transferred from the Colorado River to San Diego and other coastal cities while decreasing the quantity of water sent to the Coachella Valley

Match the following locations with the plate boundary they are closest to (some may be used more than once)

Salton Sea

Dead Sea in Israel

Convergent boundary

Transform boundary 

Divergent Boundary

Which of the following is true of convection

It is circular motion of matter

in which warmer fluids rise

and move sideways as they cool

then fall after they cool

then move sideways as they start to warm again

it can happen in liquids

it can happen in gases

it can happen in solids

the sideways movement of cooling magma in a convection cell is what causes continental drift

formed from cooling magma or lava

Marble

formed from weathered rock particles cemented together

formed from other rocks chemically and structurally altered after being exposed to  heat and extreme pressure

Obsidian

Limestone

Granite

Quartzite

Igneous

Sedimentary

Metamorphic

weathering

movement of rocks or soil by wind or water

caldera

break down of rocks into small particles by wind or water

subduction

pushing of one continental plate under another

continental drift

pressurized magma pushing up through the earth's crust

erosion

movement of continental plates across the surface of the world

eruption

a large volcanic crater formed from an eruption followed by the collapse of the mouth of the volcano

Describe which was true at the Aral Sea

The Aral sea had no outlet

The water in the rivers that fed the sea were diverted to grow cotton and other crops

The Sea was rapidly drying up, exposing the dry seabed to the wind and destroying the environment and economy of communities around it

Kazakhstan built a dam to separate the sea into a higher North Aral Sea and a lower South Aral Sea

The North Aral Sea is now more salty than the South Aral Sea

Coastal communities on the North Aral Sea now have many jobs fishing again

Nothing can grow on the dry seabed once covered by the Aral Sea
