Earth’s Systems 🌍
What is the name of the Earth system that includes all living things, like plants and animals?
What is the biosphere?
Name one reason why water is important for living things.
Water helps regulate body temperature, provides a habitat for many organisms, or is needed for plant growth.
Which part of Earth receives the most direct sunlight?
What is the Equator?
The biosphere includes all plants, animals, and humans.
True – The biosphere includes all plants, animals, and humans.
Why is it important to recycle?
Recycling reduces waste, conserves natural resources, and keeps the environment clean.
What is the name of the Earth system made up of rocks, soil, and minerals?
What is the lithosphere?
What is the process called when water turns into vapor and rises into the air?
What is evaporation?
What is the role of the sun in sustaining life on Earth?
The sun provides heat and light, helps plants grow through photosynthesis, and supports all life.
The lithosphere includes all of Earth’s air and gases.
False – The lithosphere is made of rocks, soil, and minerals, not air and gases.
Why were National and Provincial Parks created?
National and Provincial Parks protect nature, wildlife, and important historical or cultural sites.
Which Earth system includes all of the water on Earth?
What is the hydrosphere?
Name two ways humans can conserve water.
Turn off taps when not in use, take shorter showers, fix leaks, use rainwater for plants, etc.
Why do we have seasons?
Seasons happen because Earth's axis is tilted as it orbits the sun, causing different parts of Earth to receive more or less sunlight throughout the year.
Sunlight is more direct at the North and South Poles than at the Equator.
False – The Equator receives the most direct sunlight, not the poles.
Name two actions you can take to help conserve energy and natural resources.
Turn off lights when not in use, reduce water usage, walk or bike instead of driving, recycle, etc.
What are the four Earth systems?
What are the atmosphere, lithosphere, hydrosphere, and biosphere?
How do First Nations, Métis, and Inuit cultures view water?
First Nations, Métis, and Inuit cultures view water as sacred and believe in protecting it as a gift from nature that sustains all life.
What would happen if Earth received no sunlight?
Without sunlight, plants couldn't perform photosynthesis, temperatures would drop, and most living things would not survive.
Recycling helps protect natural resources.
True – Recycling helps protect natural resources by reducing waste.
How can you help protect animals in your community?
Help clean up trash, protect habitats, avoid using harmful chemicals, support conservation programs.
How do the four Earth systems interact in the water cycle?
The hydrosphere provides water that evaporates into the atmosphere. The atmosphere forms clouds, which bring precipitation to the lithosphere. The lithosphere provides land and soil for the biosphere, where plants and animals grow.
If a river in your town were polluted, how could this affect the other Earth systems?
Pollution in the river can harm plants and animals in the biosphere, make the water in the hydrosphere unsafe to drink, impact the air (atmosphere) through harmful chemicals, and damage the soil in the lithosphere.
If you could travel anywhere on Earth to find the hottest place, where would you go and why?
You would go to places near the Equator, like the Sahara Desert, because they receive the most direct sunlight year-round.
The hydrosphere includes only freshwater lakes and rivers.
False – The hydrosphere includes all water on Earth, including freshwater, saltwater, and even water vapor in the atmosphere.
What would happen if people did not practice conservation?
If people didn’t conserve resources, we would run out of clean water, air, and natural habitats, which would harm plants, animals, and humans.
