Chalk is a soft white powdery limestone that's made with fossil shells of foraminifers. Chert is a hard dark opaque sedimentary rock which is made of silica with an amorphous fine grained texture.
Wind carries heat, moisture, pollutants, and pollen to new areas. Many daily weather patterns depend on wind. A coastal region, for instance, undergoes changes in wind direction daily. The sun heats the land more quickly than the water.
Answer:
Deserts
Explanation:
A desert is a region on the earth surface with little to no rainfall all year round. Deserts also experience a wide range of temperatures daily. During the day, temperature is very high, at night, temperature falls rapidly and it is cold.
These extremes of conditions coupled with some other factors makes deserts badlands for plant growth. The soil is very lose here and contains little to no nutrients. Organic matter is non-existent due to low biodiversity.
Plants that grow in such conditions are called xerophytes. An example is cactus. They have evolved to survive and adapt to such extremes of conditions.
Examples of such deserts around the world are Sahara desert, Namib desert, Atacama desert, Kalahari desert etc.
Answer:
supply
Explanation:
In Economics, a "supply" refers to <u>the amount/quantity of goods that a seller/producer is willing to sell/produce.</u> It goes hand-in-hand with the word "demand," which refers to the <u>amount/quantity of goods that a buyer/purchaser is willing to buy/purchase.</u>
For example, a seller wishes to sell junk food in his convenience store because he hopes to profit from it. The quantity of junk foods he wishes to sell is called the "supply."
Answer: EVAPORATION.
Explanation: Salinity can be defined as the saltiness or the concentration of salt dissolved in a body of water. Measured in grams of salt divided by the kg of water.
Evaporation increases the salinity of water. Basically, evaporation is the process of converting liquid into gaseous state. In essence, concentration of a solution can be increased by evaporation and since the salinity of water is measured in grams of salt divided by the kg of water, therefore, the lesser the amount of water per salt, the higher the salinity.
