Spheres of the Earth
Which sphere includes all the water on Earth?
Hydrosphere
Plants prevent soil from washing away into rivers. Which two spheres interact?
Biosphere + Lithosphere + Hydrosphere
What does conservation mean?
Protecting Earth’s land, water, living things, and air
Why is water important for living things?
They need it to survive
Which sphere includes water?
Hydrosphere
Which sphere includes all living things on Earth?
Biosphere
Water washes and shapes rocks into sand. Which spheres interact?
Lithosphere + Hydrosphere
Name one way to conserve water at home.
Turning off water when brushing teeth
What role does sunlight play in life on Earth?
Provides heat and energy for living things
What does conservation mean?
Protecting Earth’s land, water, living things, air
Give an example of something in the lithosphere.
Rocks, soil, mountains, cliffs
Living things need water to grow. Which spheres are involved?
Biosphere + Hydrosphere
How does planting trees help the Earth?
Prevents soil erosion, provides oxygen, supports habitats
What happens if lots of glacier ice melts?
Water levels rise, affecting hydrosphere and possibly lithosphere
What happens if many trees are cut down?
Soil may erode, habitats lost; affects biosphere + lithosphere
What is the layer of air around Earth called?
Atmosphere
The sun heats water causing evaporation. Which spheres interact?
Atmosphere + Hydrosphere
Why is recycling important for the Earth?
Reduces waste and protects resources
Alberta has more sunlight in which season?
Summer
Name one way the lithosphere and biosphere interact.
Plant roots hold soil together
Name all four spheres of Earth.
Lithosphere, Hydrosphere, Atmosphere, Biosphere
Give an example of how humans can affect multiple spheres at once.
Cutting down trees affects biosphere, lithosphere, and hydrosphere
Give an example of protecting wildlife habitats.
Not littering, creating protected areas, avoiding pollution
Explain how the sun affects the water cycle.
Sun heats water → evaporation → clouds → precipitation
What might happen if lots of glacier ice melts?
Flooding, rising water levels, change to habitats
