Wind is the horizontal movement of air from an area of high pressure to an area of low pressure.
Winds are caused by differences in air pressure.
These differences are caused by the uneven heating of the Earth’s surface.
Winds are named by their direction (where they originate from) and speed.
Wind speed is measured by an anemometer.
v Local Winds: winds that blow over short distances-caused by the uneven heating of Earth’s surface within a small area. They form only when large-scale winds are weak.
Ø Sea Breeze: a local wind that blows from an ocean or a lake.
§ Occurs because land heats up faster than water – The warm air expands creating an area of low pressure over the land, so the cooler more dense air moves toward the low-pressure land area.
Ø Land Breeze: a local wind that blows from the land toward water
§ Occurs because land cools faster than water – The low pressure (less dense) air is now over the water. The warm less dense air rises so the cooler air from the land moves toward that low pressure area by the water.
Answer:
Explanation: The water cycle, also known as the hydrologic cycle or the hydrological cycle, describes the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time but the partitioning of the water into the major reservoirs of ice, fresh water, saline water and atmospheric water is variable depending on a wide range of climatic variables.
Answer is: the density of the material is 0.8 g/cm³.
m(material) = 6.75 g; mass of unknown material.
V(material) = 9 cm³; volume of unknown material.
d(material) = m(material) ÷ V(material).
d(material) = 6.75 g ÷ 9 cm³.
d(material) = 0.75 g/cm³; density of unknown material.
The most comprehensive story of ancient environment is traced by type of Sedimentary rocks. The different ancient environment forms different kinds of sedimentary rocks in terms of shape, size, pattern of sorting etc.
For example:
an ancient environment of lake will have laminated sedimentary rocks while a deserted one will have cross beds or granules.
Not only this we can also have an idea about the kind of flora and fauna of ancient environment based on the fossils. which may be in the form of architectural features.
So they reveal both kind of life / living organism and the kind of earth like river, desert, lake, swamp, lagoon etc.
Answer:
Landscape changes over time.
Explanation:
If there is a picture, this is the correct answer.
1.5 mol H20
2.5 mol H20
O 3.5 mol NO2
O 1.0 mol NO2
Answer:
3.5 moles of NO2.
Explanation:
The balanced equation for the reaction is given below:
3NO2 + H2O —> NO + 2HNO3
Next, we shall determine the excess reactant. This is illustrated below:
From the balanced equation above,
3 moles of NO2 reacted with 1 moles H2O.
Therefore, 6.5 moles of NO2 will react with = (6.5 x 1)/3 = 2.17 moles of H2O.
From the above calculations, we can see that it will take a higher amount i.e 2.17 moles than what was given i.e 1 mole of H2O to react completely with 6.5 moles of NO2.
Therefore, NO2 is the excess reactant and H2O is the limiting reactant.
Next, we shall determine the number of mole of the excess reactant that reacted in the reaction. This is illustrated below:
From the balanced equation above, we can see that 3 moles of NO2 reacted with 1 mole of H2O.
Finally, we shall determine the leftover mole of the excess reactant after the reaction. This is illustrated below:
Given mole of NO2 = 6.5 moles
Reacted mole of NO2 = 3 moles
Leftover mole of NO2 =...?
Leftover mole = Given mole – Reacted mole
Leftover mole of NO2 = 6.5 – 3
Leftover mole of NO2 = 3.5 moles.
Therefore, 3.5 moles of NO2 remained after the reaction.
