Answer:

Tiny droplets of water and ice.

Explanation:

Clouds are made of tiny water droplets and ice. The water droplets are tiny that they cant float in the air.

The air contains gas but are in the form of invisible gas when close to the earth ( water vapour).

Warm air expands and cool when it rises but cool air can not hold as much water. Some of the vapour condenses into tiny pieces of dust floating in the air to form tiny water droplets around the dust particles.

These droplets come together to form a visible cloud.

Describe the importance of biomes such as forests, freshwater, and marine biomes? How have human actions affected these biomes?

Allisa [31]

Forest biome: It gives us medicinal plants, woods for commercial purpose. Forests provides us rubber and fibers that is very important for the industries for making various products. They also contribute to perform ecological functions such as carbon storage, nutrient cycling, water and air purification. It also provides habitat to the wildlife.

Freshwater biome: We use fresh water for drinking water, irrigation, sanitation systems, and in industrial factories. Water used from groundwater, rivers and lakes is regained by rain and snowfall.

Marine biome: It serves huge amount of oxygen into the environment and absorbs the atmospheric carbon dioxide.

As a result of the activity of human there is a significant decrease in the number of trees. The products now used are synthetically made which were made up of natural fibers previously. The water source such as rivers, lakes, and ponds are polluted due to which many water borne diseases are increasing day by day. The accumulation of waste which are found in marine biome are reducing the number of flora present inside marine ecosystem.

A student has twenty identical young plants how does the amount of water given to these plants each day effect how tall the plan

mel-nik [20]

Answer:

The amount of water given to the plants depends on the effect of how tall the plant can overall grow. For instance, if all twenty identical plants are being given the same amount of water, then they will grow all at equal rates. However, if there is not equal amount/consistency with the amount of water the plants receive, then this factor may contribute to an uneven growth pattern between all twenty plants. However, other factors (such as location, sunlight, etc.) may also contribute to a plant's growth.

Scientists have discovered that the inner core of Earth is a solid while the outer core is a liquid. What is the cause of this o

Arte-miy333 [17]

Answer:

Scientists figured out that the outer core must be liquid because S waves do not pass through it, but P waves do. The behavior of P and S waves also indicates that the inner core is solid. The speed of seismic waves also depends on the density of the material through which they are traveling.
