Properties of the ocean
what is salinity? Where is it the highest in the ocean?
How much salt is in water. The deep ocean
What is hazardous waste?
trash that is ignitable, corrosive, reactive and/or toxic.
what does pH measure?
how acidic or basic a substance is
What is albedo?
Your answer must include an example of a high albedo surface and a low albedo surface.
Albedo is a measure of how well a surface reflects sunlight back into space.
High: snow, white pavement, ice
low: black top, dark pavement, oceans
Water can dissolve more things that any other natural substance, this is why it is referred to as a....
universal solvent
Name a negative environmental impact of incinerators
the release of toxic air pollutants
human health risks
contaminating near by water and soil
What does it mean to say that the ocean is a carbon sink?
What is urban sprawl?
the expansion of cities into rural areas. This causes the areas to be more spread out, car dependent and leaves the cities with funding.
This layer of the ocean sits between the deep and shallow waters and seperates the warm upper layer and cold deep water layer
the thermocline
How are the urban heat island effect and albedo related?
cities and more urban areas have lower albedos because they have fewer green areas. This means they absorb more of the sunlight instead of reflecting it back to space which causes warmer temperatures.
What is the relationship between sea level rise and sea ice shrinking?
When arctic sea ice melts faster than it re freezes in the winter then it shrinks. the melted water goes into bodies of water and causes the sea level to rise.
identifying a desired trait in an organism. Then taking the gene from that organism and inserting it into the DNA of another organism.
Why is it important that water is transparent and lets sunlight through to layers of the ocean.
so that photosynthetic organisms have light to produce energy
What is one benefit of choosing incinerators over landfills for municipal solid waste removal?
Shrinks the volume of waste
Can be used to make energy by capturing the heat from combustion
dissolving shells
decreased coral growth rates
vulnerable habitats
less available carbonate for organisms to make shells
Explain how noise pollution in the ocean affects animals
Disrupts animal's ability to communicate with each other through natural sounds.
Can cause stress on animals and mess with migration patterns.
Why is water saltier and colder at the bottom of the ocean?
Because saltier water is more dense which causes it to fall and hot water rises.
What are some solutions to the urban heat island effect
green roofs
increasing green space
using light colored pavement
What is recharge? What is discharge?
Recharge: when water moves into an aquifer through rain or floodwaters
Discharge: when water moves out of an aquifer through springs, rivers or wells
