Unit 6 Warm ups

Question 1

What is the difference between climate change and global warming

Answer 1

climate change= any change in Earth’s climate including global trends in warming, cooling, precipitation, wind direction etc.

Global warming- an INCREASE in average temperature of Earth’s surface

Question 2

What are the main factors that influence Earth’s climate

Answer 2

Earth’s tilt and orbit

tilt- area getting different amounts radiation

orbit- when Earth’s orbit is more circular it leads to lower temperatures

Question 3

Most of the energy reflected from Earth is in the form of what

Answer 3

Infrared Radiation

Question 4

Are greenhouse gasses themselves bad

Answer 4

No.

Without greenhouse gases, Earth’s average surface temp would be -18 degrees Celsius.

They are gases in the atmosphere that absorb and reflect back energy to keep Earth warm

Question 5

What are our greenhouse gasses. Name them

Answer 5

water vapor, CO2, methane, nitrous oxide

Question 6

What on Earth absorbs great amounts of Carbon Dioxide

Answer 6

Earth’s Oceans

Question 7

How does the Ocean’s temps. impact greenhouse gas

Answer 7

A colder ocean can absorb and store more CO2, allowing for cooler temps.

A warmer ocean can’t absorb and store as much CO2, causing for warmer temps.

Question 8

What is the importance of ocean currents on climate

Answer 8

Ocean currents move warm water from the equator to the poles and cold water from the poles to the equators. This allows for the climate to be less extreme in the poles and close to the equator.

Question 9

What 2 events can break ocean current cycles along the equator

Answer 9

El Niño and la Nina- they cause the gulf coast to be wetter than normal

Question 10

What geologic processes move carbon naturally

Answer 10

plate motion

Question 11

What impacts do volcanic gasses have

Answer 11

Volcanic Eruptions disperse CO2 and sulfur dioxide into the atmosphere.

When sulfur dioxide is released into the atmosphere, its high albedo can cool Earth for years.

The CO2 released can heat Earth, but this may not last as long as the cooling

Question 12

What impact can meteorites have on Earth’s climate

Answer 12

When meteorite particles go into the air, they block the sun and cool Earth’s climate

Question 13

How have plants changed the global climate

Answer 13

They release oxygen into the atmosphere, leading to CO2 in the biosphere. Because of less carbon in the air, there is less heat, leading to a cooler climate

Question 14

What 3 processes are part of the slow cycling of carbon

Answer 14

weathering
formation of sedimentary rocks
volcanic activity

Question 15

Where does fast cycling of carbon occur

Answer 15

biosphere- through photosynthesis and cellular respiration, organisms are able to move carbon between the biosphere and atmosphere quickly

Question 16

What has the IPCC determined as the leading causes of climate change

Answer 16

the increase of greenhouse gases (Co2) into the atmosphere through burning fossil fuels and deforestation

Question 17

How does deforestation affect climate

Answer 17

Plants allow for the removal of Co2 and pollution from the atmosphere but when being cut down, there is less carbon dioxide that is being absorbed leading to an increase in climate

Question 18

What is the impact of climate change on Earth’s waters

Answer 18

An increase in climate leads to waters warming, becoming more acidic(because of more CO2 absorption), and water levels increasing (because ice melts).

Increased temperatures also leads to increased evaporation and therefore more rain and flooding in wet regions, while it also increases drought in drier areas

Question 19

What causes coral to lose their color?

Why does this occur?

Answer 19

Because coral are sensitive to temperature changes, when water temp, increases, it causes coral to release their photosynthetic algae (main source of energy).

Question 20

What is one of the largest outputs of carbon emissions

Answer 20

cities- 75% of global carbon emissions.

Question 21

Explain the negative effects of deforestation. Be sure to include and discuss why it has such a negative impact in regards to the carbon cycle

Answer 21

By using photosynthesis, plants help remove CO2 from the atmosphere allowing for a cooler climate. When plants and trees are cut though, carbon dioxide cannot be moved into the biosphere, and it leads to an increase in temp and climate. This doesn’t allow for stable exchange in the carbon cycle and leads to more carbon in the atmosphere

Question 22

What is biomass

Answer 22

the burning of organic matter such as wood, peat, and plant oils.

Question 23

how does biomass impact the carbon cycle

Answer 23

The burning of biomass doesn’t impact the carbon cycle because the burning of them release carbon that absorbed by the growing of the tree/plant. There is additional carbon as the same same carbon absorbed from the atmosphere from the plant during its growth is the same carbon released whether by people burning it or by it decaying and decomposing naturally.

Question 24

How do natural disasters such as volcanic eruptions impact climate.

Question 25

Are natural disasters such as volcanic eruptions short or long term changes

Question 26

How do growing seasons impact carbon capture in plants

Question 27

What is the greenhouse effect and how does it work

Question 28

Discuss things about the Earth that impact our climate

Question 29

What is albedo and how does it affect solar energy absorbed or reflected back into the atmosphere

Question 30

How does urbanization affect climate? Discuss the impact and what can be done to help minimize or reduce that impact

Question 31

Carbon cycles in the atmosphere at different rates throughout the year. Producers play a huge role in this. Why do carbon rates fluctuate over the course of a year

Question 32

What are ways carbon is captured? What are ways carbon is released

Question 33

What are some things that indicate changes to Earth’s climate

Question 34

What are ways that carbon is quickly cycled on Earth

Question 35

What are ways that carbon is slowly for cycled n Earth

Question 36

What cell organelle is responsible for making proteins

Question 37

Explain how to distinguish between and independent and dependent variable.
