Q

Describe the 4 Earth systems

A

Biota-collection of living things that live in the biosphere.
Atmosphere-the air blanketing the earth’s solid and liquid surfaces
Hydrosphere-all of Earth’s water , ice and water vapor
Geosphere-the features of the earth’s surface such as the continents, rocks and the sea floor., and everything below Earth’s surface.

Q

What are the 3 climate zones on Earth? Describe each.

A

Polar-at the far north and south poles very cold and often below freezing.

Temperate-Broad area between the polar and tropical climate has summer and winter seasons of about equal length.

Tropical-Surrounds the equator and runs from the tropic of Cancer to the tropic of Capricorn, and has warm moist conditions.

Q

List and describe the 4 zones of the ocean.

A

Intertidal zone-strip of land between the high and low tide zones. The beach. Organisms must tolerate a variety of conditions.

Neritic zone-from the intertidal zone to the edge of the continental shelf.

Bathyal zone- from the edge of the neritic zone to the base of the continental shelf. Water is murky as has burrowing animals
.
Abyssal zone- below 2000 meters and in complete darkness. No photosynthetic organisms. Many organisms make their own light.

Q

Why are estuaries sometimes called the nursery of the sea?

A

Highly productive ecosystem, highly photosynthetic organisms thrive providing the basis for the aquatic food web. Their protective refuge provides a good place to lay eggs.

17
Q

What is a watershed?

A

A region of land that drains into a river, river system or another body of water.

18
Q

Name and describe the three zones of lakes and ponds

A

littoral zone-located between the high and low water marks along the shoreline. Well-lit, warm, shallow a diverse set of organisms such as dragonflies, water lilies, and snails.

limnetic zone-open water located further out from shore. Abundance of Plankton communities to support populations of fish.

benthic zone-lake or pond bottom, less sunlight reaches so decomposers such as bacteria live in the mud and sand.

19
Q

Explain the difference between renewable and nonrenewable resources. Give examples of each.

A

Nonrenewable-used faster than they form. Coal and Oil

Renewable-resources can not be used up or replenish themselves over time.

20
Q

What is an ecological footprint?

A

The amount of land necessary to produce and maintain enough food and water, shelter energy and waste.

21
Q

Which continent has the largest ecological footprint?

A

North America

22
Q

What is pollution?

A

Any undesirable factor , or pollutant that is added to the air, water or soil.

23
Q

What is smog? What are the components of smog?

A

A type of air pollution caused by the interaction of sunlight with pollutants produced by fossil fuel emissions (cars etc.)
Composed of particulate matter, dust metal
ground-level ozone 03.

24
Q

What is acid rain? What is the pH of normal rain? The pH of acid rain?

A

A type of precipitation that is produced when pollutants in the water cycle cause rain ph to drop below normal levels.

25
Q

What is the greenhouse effect?

A

When carbon dioxide, water and methane molecules absorb energy radiated by Earth’s surface and slow the release of this energy from Earth’s atmosphere.

26
Q

What is global warming?

A

The trend of increasing global temperatures.
