What is CLimate?
is the long-term pattern of weather conditions in a particular region
100
describe Earth’s average surface temperature during this time period
Earth's surface temperature increased after 1940 because of increased greenhouse gases
100
At which locations does carbon dioxide enter Earth’s atmosphere?
B, D, C
100
When plants and animals die, their carbon is released back into the environment by bacteria and fungi through a process called -
Decomposition

Humans depend on the ocean for factors such as climate regulation, food, and transportation. Natural events and human activities can influence an ocean ecosystem.
WHat is an activity will most likely have a positive impact on an ocean ecosystem?
Building artificial reefs
Decreasing fishing
200
How do humans impact Earth's climate?
Human activities, such as burning fossil fuels, increase greenhouse gases in the atmosphere, which leads to global warming/climate change
200
Which human activity causes a population shift from rural areas to cities, leading to an increase in fossil fuel emissions?
Urbanization
200
The Rocky Mountains in North America and the Scandinavian Mountains in Europe exhibit similar rock formations and ages. This suggests that these mountain ranges were once part of the same landmass before gradually separating and drifting apart over time. This observation provides evidence of -
Plate tectonics
200
Meteor impacts can significantly affect Earth’s climate by releasing large amounts of dust and debris into the atmosphere. This can lead to disruptions in ecosystems and food supplies. The Chicxulub meteor, which struck Earth around 66 million years ago, is thought to have caused substantial climate change and contributed to the mass extinction of dinosaurs.
Which statement accurately describes the effects of the impact
A. The impact caused cooling of Earth’s surface by releasing dust and debris that blocked sunlight.
b.The impact caused warming of Earth surface by creating a large fireball that emitted heat.
c.The impact caused heating of Earth’s surface by releasing greenhouse gases that trapped sunlight.
d.The impact caused an increase in ocean temperatures by releasing lava into the ocean.
A
200
Carbon moves into the mantle during the process of subduction, when one tectonic plate sinks beneath another.
Describe how carbon returns to Earth’s atmosphere
Carbon returns to Earth’s atmosphere through volcanic eruptions
300
How does deforestation impact the environment in terms of carbon?
Deforestation releases carbon dioxide into the atmosphere
Deforestation reduces the amount of carbon dioxide absorbed through photosynthesis
300
Ocean currents are large streams of seawater that move continuously through the world’s oceans. Warm ocean currents carry warm water from the tropics to the polar regions, while cold ocean currents carry cooler water from the polar regions to the tropics. Various factors can influence these currents.
What effect does global warming have on Earth’s ocean currents?
Global warming can cause ocean currents to slow down or stop, leading to extreme temperatures.
300
describe the process Letter E represents
It represents photosynthesis, which absorbs carbon dioxide from the atmosphere.
300
Which of the following describes evidence that supports the theory of plate tectonics?
a.Similar rock patterns are found on the same mountain ranges.
b.Different glacial striations indicate that Earth’s plates are stationary.
c.Similar types of fossils are discovered on different continents.
d.Different weather patterns occur across different continents.
C
300
describe an effect a human activity can have on the watershed
Fertilizer is carried by runoff into the river, causing an overgrowth of water plants.
Pollution goes into the water
400
How can volcanic eruptions decrease global temperatures?
The gases and particles from the eruption temporarily blocked sunlight
400
WHat type of plate boundary causes rift valleys?
Divergent
400
A teacher asks students to use blocks to represent a convergent boundary. The students push two blocks toward each other.
Which event did the students best demonstrate?
Mountain formation
400
Describe the motion of each type of tectonic plate activity and what they form
Convergent- together (mountains, trenches)
Divergent- apart (rifts, ridges)
Transform- slide (earthquakes, fault lines)
400
Eutrophication can cause dead zones in the ocean. Dead zones occur when excess nutrients, such as nitrogen and phosphorus, lead to algal blooms, or an overgrowth of algae. What effect do algal blooms have on the ocean?
Algal blooms result in decreased oxygen supplies in the ocean.
500
Which of the following natural events have the most influence on Earth's climate?
A. Meteor impacts, volcanic activity, local wildfires
B. Earthquakes, flooding, and plate tectonic activity
C. Meteor impacts, volcanic activity, and abrupt chances in ocean currents
D. Earthquakes, plate tectonic activity, local wildfires
C
500
Human Activities That Impact Ocean Systems
I. Overfishing
II. Building artificial reefs
III. Limiting fishing
IV. Introducing invasive species
V. Burning fossil fuels
Which activities will most likely have a negative impact on ocean ecosystems?
I, IV, V
500
Letter A and Letter C represent the process of ________ that occurs when plants and animals take in oxygen and release carbon dioxide back into the environment.
Respiration
500
Carbon dioxide is absorbed by Earth’s oceans. Describe an effect of increased levels of carbon dioxide in the ocean systems
The Temp increases pH decreases
500
What is the carbon cycle AND how does it help stabilize Earth’s climate
The carbon cycle is the process of carbon moving from the earth and the atmosphere
It stabilizes the climate by balancing carbon and regulating Earth's temperature
