Example Question #1 : Explain How Water On Earth Can Be Solid Or Liquid

The photo below represents water in what state(s)?

Iceberg, Ice, Water, Frozen, Melting

Possible Answers:

Solid

Neither solid nor liquid

Both solid and liquid

Liquid

Correct answer:

Both solid and liquid

Explanation:

Water on Earth can be found in both the liquid and solid states depending on the temperature and conditions of the environment it is in. In this photo, both states of water are present. There is liquid water in the ocean or sea, and the large blocks of ice are solid glaciers.

Example Question #1 : Explain How Water On Earth Can Be Solid Or Liquid

Which photo represents water in a liquid form?

Possible Answers:

Water, Clear, River, Waters, Bach

Nigardsbren, Glacier, Ice, Melt, Nature

Icicles, Branches, Ice, Tree, Frozen

Ice Cubes, Ice, Frozen, Transparent

Correct answer:

Water, Clear, River, Waters, Bach

Explanation:

Water on Earth can be found in both liquid and solid states. Three of the photographs show water in the solid form - the glacier, the ice cubes, and icicles are frozen water. The only photo that demonstrates water in a liquid form is the waterfall.

Example Question #1 : Identify Where Water Is On Earth

Which answer choice correctly lists places where water can be found on Earth?

Possible Answers:

Oceans, underground, ponds, and streams

Glaciers, lakes, icebergs, and rivers

Rivers, ponds, oceans, and lakes

All of the choices list places where water can be found.

Correct answer:

All of the choices list places where water can be found.

Explanation:

Water is everywhere on Earth. It can be found underground, in glaciers, icebergs, lakes, streams, ponds, rivers, and oceans. About 72% of the Earth is made up of water! Looking at maps of the world can help put into perspective how much water there is on Earth.

Example Question #2 : Identify Where Water Is On Earth

Which image correctly identifies where there is water on Earth?

Possible Answers:

Screen shot 2020 06 04 at 1.12.56 pm

Screen shot 2020 06 04 at 1.10.13 pm


Screen shot 2020 06 04 at 1.11.26 pm

Screen shot 2020 06 04 at 1.12.01 pm

Correct answer:

Screen shot 2020 06 04 at 1.12.01 pm

Explanation:

These four images are from the same portion of the world map. A map is a great place to look for landforms, bodies of water, and landmasses. When using a map, all bodies of water will be blue, and the land may be tan, green, or in this case, multiple colors to distinguish between the countries. You may also notice that the water is not labeled. Maybe times, there will be one label for an ocean or sea, but because it is so large, there may be portions that look unlabeled.

Example Question #3 : Identify Where Water Is On Earth

Water is found in the ocean, rivers, lakes, and ponds.

Possible Answers:

True

False

Correct answer:

True

Explanation:

The statement is a fact, so it is true. Water can be found in oceans, rivers, lakes, ponds, and more locations. Almost three-quarters of our Earth is made of water, so you are likely to find it if you go looking.

Example Question #4 : Identify Where Water Is On Earth

Where is most of Earth's water?

Possible Answers:

In our bodies

In the sink

In the ground

In the oceans

Correct answer:

In the oceans

Explanation:

Most of Earth's water is found in our oceans. About 72% of the Earth is made of water, and the oceans hold about 96% of that water! Earth has water in other places (streams, underground, glaciers, icebergs, ponds, etc.), but the majority can be found in the ocean.

Example Question #2 : Identify Where Water Is On Earth

Which part(s) of this world map identifies where water is on Earth?

Map, Earth, World, Planet, Environment, Country, Water

Possible Answers:

The tan part of the map.

The brown part of the map.

The green part of the map.

The blue and white parts of the map.

Correct answer:

The blue and white parts of the map.

Explanation:

When using a resource like a world map to identify where water is located on Earth, one must look for the blue and white portions of the map. Tan and green are the parts of Earth that are land. White represents clouds or at the top and bottom of the map, frozen water. The blue portions are bodies of water.
