Science worksheet on Earth's major systems for 5th grade, including labeling exercises and a diagram of Earth's spheres.

Let’s go step by step to solve this homework.

---

Part 1: Match each description to the correct Earth system — Geosphere, Atmosphere, Hydrosphere, or Biosphere.

We’ll use what we know about each sphere:

- Geosphere: Rocks, soil, mountains, land, sediments — anything solid on or in Earth.
- Atmosphere: The air around us — gases, clouds, weather, sky layer seen from space.
- Hydrosphere: All water — oceans, rivers, lakes, ice, snow, rain.
- Biosphere: All living things — plants, animals, humans, bacteria.

Now let’s match each item:

a) Ice and snow → These are frozen water → Hydrosphere
b) Rocks and Earth’s solid → That’s the ground/land → Geosphere
c) Made of gases → That’s the air → Atmosphere
d) Has all living things → Plants, animals, people → Biosphere
e) Rivers, lakes, oceans → Water bodies → Hydrosphere
f) Humans live here → We live on land (geosphere), but also need air (atmosphere) and water (hydrosphere). But since it says “live here” and shows a diagram with land, it’s mostly referring to Geosphere — though technically biosphere includes where life exists. Wait — let’s think again.

Actually, for f): “Humans live here in the ___” — looking at the diagram in Part 2, humans would be on the land part, which is geosphere. But strictly speaking, humans are part of the biosphere, and they live *on* the geosphere. However, the question is asking which sphere they “live in”. In science class, when they say “humans live here”, they usually mean the surface of the Earth — so Geosphere. But let’s check standard answers.

Wait — actually, many textbooks say that the biosphere is where life exists, including where humans live. So if the question is “humans live here in the ___”, and one option is biosphere, then it should be biosphere, because biosphere = zone of life.

But let’s look at d): “has all the living things on Earth” → that’s clearly biosphere.

So for f): “Humans live here in the ___” — since humans are living things, and they live within the biosphere, it should still be biosphere? Or maybe they mean physically on the land?

Looking at common school worksheets: often “humans live on the geosphere” is accepted, but technically, the biosphere overlaps with geosphere, hydrosphere, and atmosphere.

However, given the options and typical 5th grade level, let’s see:

In many similar worksheets:
- “Humans live on the geosphere” is used to mean the land surface.
- But “biosphere” is defined as the part of Earth where life exists — so humans are part of biosphere and live within it.

This is tricky. Let me check the diagram clue: in Part 2, there’s a landscape with land, water, sky, trees, fish, sun, clouds. The blank boxes are likely labeling spheres.

Also, note that in Part 1, item d already says “has all the living things” → biosphere.

Item f: “Humans live here in the ___” — probably expects geosphere, meaning the solid ground we stand on.

But wait — let’s think logically: if you’re standing on dirt, you’re on geosphere. If you’re breathing air, you’re in atmosphere. If you drink water, you’re using hydrosphere. But your body is part of biosphere.

The question is ambiguous, but in most elementary science contexts, “humans live on the geosphere” is the expected answer for “where do humans live?” meaning the physical place.

However, I recall that some curricula teach that the biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the lithosphere (geosphere), hydrosphere, and atmosphere.

Given that, and since item d already covers “all living things”, perhaps f is meant to be geosphere.

Let me look for consistency.

Another way: let’s list all and see if any conflict.

g) Seen from space as blueish thin layer → that’s the atmosphere (sky looks blue from space? Actually, Earth looks blue because of oceans, but the “thin layer” suggests atmosphere. Yes — astronauts see the atmosphere as a thin blue line.)

h) Sediments and soil → definitely geosphere

i) All liquid water → hydrosphere

Back to f: “Humans live here in the ___”

If we put biosphere, then d and f both point to biosphere — which is fine, since d is “has all living things” and f is “humans live here” — humans are living things, so they live in the biosphere.

Actually, that makes sense. The biosphere is the realm of life. So even though we stand on geosphere, we are part of and live within the biosphere.

I think the intended answer is biosphere for f.

But let’s double-check with standard definitions.

Upon second thought, in many K-8 science resources:

- Geosphere: rocks, minerals, landforms
- Hydrosphere: water
- Atmosphere: air
- Biosphere: living organisms and where they live

So “humans live here” — since humans are living, and they inhabit parts of geosphere, hydrosphere, and atmosphere, the best fit is biosphere.

Yes, I’ll go with that.

So:

a) Hydrosphere
b) Geosphere
c) Atmosphere
d) Biosphere
e) Hydrosphere
f) Biosphere ← humans are living things, so they live in the biosphere
g) Atmosphere ← the thin blue layer seen from space is the atmosphere
h) Geosphere
i) Hydrosphere

Wait — g: “can be seen from space as a blueish thin layer” — actually, from space, Earth appears blue mainly due to oceans (hydrosphere), but the “thin layer” refers to the atmosphere. Astronauts describe the atmosphere as a thin blue haze around the planet. So yes, atmosphere.

Okay, finalizing Part 1:

a) Hydrosphere
b) Geosphere
c) Atmosphere
d) Biosphere
e) Hydrosphere
f) Biosphere
g) Atmosphere
h) Geosphere
i) Hydrosphere

Part 2: Label the picture

The picture has several blank boxes pointing to different parts. Based on the scene:

Top left box: points to the sky/clouds area → likely Atmosphere

Middle right box: points to the mountain/land → Geosphere

Bottom left box: points to the ocean/water with fish → Hydrosphere

Bottom middle box: points to the grass/trees → Biosphere (since trees are living things)

There might be another box? Looking at the image description: four blanks.

From the user's image description:

- Top left: above clouds → atmosphere
- Right side: near mountain → geosphere
- Left bottom: in water → hydrosphere
- Bottom center: on land with trees → biosphere

Yes.

So labels:

Top-left box: Atmosphere
Right box (mountain): Geosphere
Left-bottom box (ocean/fish): Hydrosphere
Bottom-center box (trees/grass): Biosphere

Note: Sometimes the sun is labeled separately, but here no box points to sun. Clouds are part of atmosphere.

Fish are in hydrosphere, but the box is pointing to the water body, so hydrosphere.

Trees are biosphere.

Mountain is geosphere.

Sky/clouds: atmosphere.

Perfect.
