Earth and Space Science - 2nd Grade Science

The sun sets in the evening. Looking at our answer choices, we have times that are in and .

Times that are in are morning times. Times that are in are afternoon and evening times.

Because the sun sets in the evening, our answer choice needs to end in .

is the middle of the night, and the sun is not out in the middle of the night. is a morning time so the sun would not be setting. is the middle of the afternoon, when the sun is at its highest point, which means that the sun would not be setting.

could be a time that the sun is setting.

The sun is at it's highest point during the afternoon, around

Around the sun is just rising, so it's at one of its lowest points.

Around the sun is setting, so it's at one of its highest points.

is the middle of the night, so it the sun is not up because it's dark.

When you reuse something, you use something again.

Once you are done drinking a bottle of water, if you throw it away you aren't going to reuse it. But, if you refill the water bottle, that is an example of reusing the bottle.

Re-buying the same type of water or water bottle is not an example of reusing something. You are just buying the item again.

The statement is true; 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.

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 a hot place like the desert, water will not be found in a solid form as ice; it would be a liquid. In somewhere that is below freezing, one would likely see frozen water known as ice. In conditions such as a thunderstorm, both liquid and solid ice can be found it there is rain and hail.

Water can be found in a liquid or solid state on Earth. The photo that represents a solid-state of matter is the ice and glaciers. These are large bodies of frozen water. The waterfall, ocean wave, and bottled water are all in a liquid form.

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

Water can be changed from a liquid to a solid by freezing it. Many times ponds and lakes become frozen over when temperatures drop, and the liquid water is turned to ice. In the wintertime in many places, instead of rain falling from the clouds, we see snow because the temperatures are freezing and the water freezes.

Earth has both liquid and solid water present. An example of how both of these forms can be found on Earth is that hail is solid, and rain is a liquid. They are both water but just in different forms. Students will learn about other forms of water and how they change in upper grade-levels.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
