Example Questions

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

How could water be changed from its solid form on Earth to a liquid form?

 

Possible Answers:

It could be melted.

It could be frozen.

It cannot be turned from a solid to a liquid.

It could be buried.

Correct answer:

It could be melted.

Explanation:

Water can be changed from a solid to a liquid by melting it. Many times ponds or lakes are frozen in the winter when the temperature is low, the water is solid, and has turned to ice. In the spring, the temperatures start to rise in many places, and the frozen water melts back into its liquid state. Other places in the world may still be cold, and water remains froze. This is how solid and liquid water can exist at the same time in different areas.

Example Question #2 : Explain How Water On Earth Can Be Solid Or Liquid

Water only exists in solid states when it is warm.

Possible Answers:

True

False

Correct answer:

False

Explanation:

The statement is false; water can be found on Earth in solid AND liquid form. Water can be found on Earth in a solid form in cold areas as ice. Water can be found in a liquid form in places such as ponds, oceans, rivers, and more. When water is located in a solid-state, it would be in cold temperatures.

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:

Liquid

Solid

Both solid and liquid

Neither solid nor 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

Ice Cubes, Ice, Frozen, Transparent

Nigardsbren, Glacier, Ice, Melt, Nature

Icicles, Branches, Ice, Tree, Frozen

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:

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

Rivers, ponds, oceans, and lakes

Glaciers, lakes, icebergs, and rivers

Oceans, underground, ponds, and streams

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 1.11.26 pm

Screen shot 2020 06 04 at 1.12.01 pm

Screen shot 2020 06 04 at 1.10.13 pm

Screen shot 2020 06 04 at 1.12.56 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:

False

True

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 #1 : Identify Where Water Is On Earth

Where is most of Earth's water?

Possible Answers:

In the oceans

In the ground

In our bodies

In the sink

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 #11 : Earth And Space Science

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

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

Possible Answers:

The brown part of the map.

The tan 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.

Example Question #81 : 2nd Grade Science

Bayou, Swamp, Marsh, Wetland, Louisiana

This is a location where water is found on Earth. What is the name of this location?

 

Possible Answers:

Ocean

Groundwater

Glacier

Swamp

Correct answer:

Swamp

Explanation:

This is a photo of a swamp. A swamp is a low-lying area that collects water. Water can be found everywhere on Earth though! Water can be found underground, in oceans, seas, ponds, lakes, rivers, glaciers, streams, our atmosphere, and more. This is just one location to find water on Earth.
