Earth & Seasons
This causes Earth to experience different seasons.
What is Earth’s tilt and its orbit around the Sun?
All of Earth’s water—liquid, solid, and gas—is called this.
What is the hydrosphere?
This process in plants is the opposite of cellular respiration
What is photosynthesis?
This gas makes up most of Earth’s atmosphere.
What is nitrogen?
Any physical hazard caused by too much or too little of needed resources is called this.
What is a stress to an ecosystem?
An organism that naturally lives in an ecosystem is called this.
What is a native species?
This season is known as a time of new growth for living things.
What is spring?
This process changes liquid water into water vapor.
What is evaporation?
Plants release water into the air through their leaves by this process.
What is transpiration?
True or False: Lightning can change nitrogen gas into usable compounds.
What is True
A series of gradual changes in organism populations is known as this.
What is succession?
An organism introduced to a new ecosystem that causes harm is this.
What is an invasive species?
Some parts of the Earth experience only this many seasons.
What are two seasons
This occurs when water vapor cools and turns into liquid water.
What is condensation?
Plants need nitrogen to grow and make these.
What are proteins?
Some nitrogen-fixing bacteria live in nodules on these plant parts.
What are roots?
This is the largest man-made stress on ecosystems.
What is habitat destruction?
This happens when fish are removed faster than they can reproduce.
What is overfishing?
God uses these repeating patterns to help maintain His Earth.
What are cycles?
Heavy seasonal winds that change direction are known as these.
What are monsoons?
These organisms reproduce by spores and do not make their own food.
What are fungi?
The movement of carbon between the atmosphere, Earth, and organisms is called this.
What is the carbon cycle?
Fire can help ecosystems by doing this.
What is recycling nutrients into the soil?
The red drum population declined in the 1980s because of this.
What is overfishing?
True or False: Changes in ecosystems always happen quickly.
False
True or False: Floods are always beneficial to the environment.
False
Bacteria and these organisms break down dead plants and animals.
What are decomposers?
This process uses oxygen to break down sugar and release energy.
What is cellular respiration?
True or False: Not all fires should be put out immediately.
What is True
What happened to the last passenger pigeon in 1914.
What is died in captivity?
True or False: Seasons are caused by how far Earth is from the Sun.
False
A long period of very little rainfall is called this.
What is a drought?
True or False: Plants can absorb water through their leaves.
What is True
What process do plants use to produce food?
What is photosynthesis
True or False: Stresses were part of God’s original good creation.
What is False
An organism that no longer exists is called this.
What is extinct?
