Oceans
What watershed are we living in?
Chesapeake Bay Watershed
Give 2 examples of non renewable resources
any petroleum based products (coal, oil, etc)
What is a watershed?
an area of land where all water drains to a common outlet
What is a fossil?
a preserved remnant or impression of an organism
What are the layers of the atmosphere in order?
Troposphere → Stratosphere → Mesosphere → Thermosphere → Exosphere
What ocean current affects our weather?
Gulf Stream
Give 2 examples of renewable resources
wind, solar, etc
What are the three main freshwater systems present on Earth?
wetlands, rivers, groundwater
Which type of fossil is formed when an organism is trapped in substances like tar, amber, or ice?
Carbon film fossil
Preserved fossil
Trace fossil
Petrified fossil
2. preserved fossil
How does the fossil record support the idea of continental drift?
Identical fossils have been found on different continents thought to have been joined in the past.
The Gulf Stream and North Atlantic Current modify the climate of northwestern Europe by making the climate
warmer and more humid
What is one advantage of using solar power over fossil fuels?
Solar power is a finite resource
Solar power does not contribute to greenhouse gas emissions
Solar panels are very expensive and difficult to install
Solar power produces air pollution
2. Solar power does not contribute to greenhouse gas emissions
How can wetlands act as a natural filter?
trapping sediments, absorbing pollutants, breaking down waste
Which of the following is an example of a trace fossil?
A complete dinosaur skeleton
A petrified tree trunk
A fossilized footprint or burrow
An insect trapped in amber
3. a fossilized footprint or burrow
Which layer of Earth’s atmosphere is where weather occurs?
troposphere
Where do warm and cold ocean currents typically originate, and how does this affect climate?
Warm currents come from the equator and warm nearby land; cold currents come from polar regions and cool nearby land
Which of the following is a common environmental concern related to mining?
Habitat destruction
Improved soil quality
Reduced water pollution
Increased biodiversity
1. Habitat destruction
Why are wetlands important to the environment as well as humans?
It acts as a natural filter to keep water clean for wildlife and acts as a natural buffer to keep flood waters at bay.
What type of fossil forms when minerals replace all or part of an organism's tissue?
Cast fossil
Trace fossil
Petrified fossil
mold fossil
3. petrified fossil
In which layer of the atmosphere would you find the ozone layer, which helps protect Earth from harmful ultraviolet (UV) radiation?
stratosphere
What is the general direction of ocean currents in the Northern Hemisphere compared to the Southern Hemisphere?
Northern Hemisphere currents move clockwise, while Southern Hemisphere currents move counterclockwise
Which of the following is a potential impact of mining on local water sources?
Increased water quality
Reduced water usage
Pollution from heavy metals and chemicals
Replenishment of groundwater reserves
3. Pollution from heavy metals and chemicals
In the past, civilizations were colonized near waterways. Why do you think this is?
Past civilizations did not have running water. It allowed for easy trade. It was an abundance of life to act as a food source for people.
What is the difference between a mold and a cast fossil?
A mold is formed from bones; a cast is from plants
A mold is a hollow impression; a cast is a filled-in copy of the organism’s shape
A mold is the exact replica of an organism; a cast is a trace
A mold is living; a cast is fossilized
2. A mold is a hollow impression; a cast is a filled-in copy of the organism’s shape
How can weather affect the location, quality, and supply of available freshwater?
Rainfall patterns determine where freshwater is most abundant. Flooding can cause contamination of drinking water supplies. Droughts drastically reduce surface and groundwater supplies.
