Soil texture, soil structure, and slope have the largest impact on infiltration rate. Water moves by
gravity
into the open pore spaces in the soil, and the size of the soil particles and their spacing determines how much water can flow in.
Which of the following best describes how ocean acidification affects coral formation?
Which of the following best describes how ocean acidification affects coral formation?
The increase in hydrogen ions dissolved in the ocean water sequesters available carbonate ions
, preventing the use of calcium carbonate for coral skeleton formation.
Which of the following will be the greatest impact of the development on the local water supply quizlet?
Which of the following will be the greatest impact of the development on the local water supply?
There will be less recharge of groundwater.
Which of the following best describes how the use of hydrogen fuel negatively impact the environment?
Which of the following best describes how the use of hydrogen fuel negatively impacts the environment?
The energy needed to produce the hydrogen fuel may come from fossil fuels
, whose use contributes to ocean acidification and global climate change.
Which of the following explains the variable that would be the best for the students to measure to determine the direct impact of soil erosion caused by the construction project on the river?
Which of the following explains the variable that would be the best for students to measure to determine the direct impact of soil erosion caused by the construction project on the river? …
Water temperature
, because a decrease in shading in the area would indicate an increase in soil erosion.
What are the four most important properties of soil?
All soils contain mineral particles, organic matter, water and air. The combinations of these determine the soil’s properties – its
texture, structure, porosity, chemistry and colour
.
Which type of soil can hold the greatest amount of water?
Generally speaking,
clay-rich soils
have the largest pore space, hence the greatest total water holding capacity.
What is ocean acidification and why is it important?
Acidification
reduces the availability of carbonate ions in ocean water
, which provide the building blocks these organisms need to make their shells and skeletons, significantly reducing the chances for their offspring to survive.
What are the effects of ocean acidification?
Ocean acidification
reduces the amount of carbonate, a key building block in seawater
. This makes it more difficult for marine organisms, such as coral and some plankton, to form their shells and skeletons, and existing shells may begin to dissolve.
What is the process of ocean acidification?
When carbon dioxide (CO
2
) is absorbed by seawater, chemical reactions occur that reduce seawater pH, carbonate ion concentration, and saturation states of biologically important calcium
carbonate minerals. These chemical reactions are termed “ocean acidification” or “OA” for short.
Which of the following is an environmental advantage of urbanization?
In cities, property values are higher and space is used more efficiently. That means that more people live in the same square mile of land than in the rural areas. Another environmental advantage of cities compared to rural areas is a
decrease in carbon emissions per person
.
What are the advantages and disadvantages of hydrogen energy?
Hydrogen is incredibly dense in energy and is able to provide a lot of power
. It is 3 times more powerful than most fossil based fuel sources so less hydrogen is required to perform the same tasks. This is why hydrogen is used in space exploration to fuel spaceships, aeroplanes, boats, cars and fuel cells.
How do fuel cells affect the environment?
Fuel cells have strong benefits over conventional combustion-based technologies currently used in many power plants and cars. They produce
much smaller quantities of greenhouse gases
and none of the air pollutants that create smog and cause health problems.
Which statement best describes an independent variable quizlet?
Terms in this set (10) Which statement best describes an independent variable?
The variable you change in an investigation.
Which explanation best describes why City B regularly receives less precipitation than City A?
Which of the following best explains why City B regularly receives less precipitation than City A?
The rain shadow effect causes City B to be drier because
the mountain blocks precipitation from reaching the city.
Which of the lettered choices in the soil profile represents the region with the greatest concentration of organic material?
Called the A horizon,
the topsoil
is usually the darkest layer of the soil because it has the highest proportion of organic material.
