Put a check mark ( ✓✓ )  next to statements that you agree with. WIND  All the air movement in the atmosphere is caused by the differences in the temperature between the neighbouring air masses. Also, the wind flows from the areaof the higher to the area of the lower air pressure. This air flow can be horizontal, vertical (upward and downward) and vortex. XXXXXXXC   XXXXXXXX  The horizontal air movement is called wind. It has a certain direction, speed and strength. The direction of the wind is marked by the side of the world from wherethe wind is blowing and is graphically shown in the wind rose. Most often there are 8 or 16 directions marked on this and in the circle in the middle a period of calm, i.e. observation without wind, is marked. The direction is determined using Wild wind vane, which is positioned at 6-12 m above the surface of the Earth.The speed is the way that a particle of air covers in one second. It is measured with an anemometer and given in m/s and depends on many different factors,most important of these being the relief, vegetation and objects present on the surface. Hills and mountains are an obstacle for the wind, unlike river valleys andplains which are favourable for its development. Forests greatly weaken the wind which is why the forest belts are grown to serve as a defence from strongwinds. Tall buildings in big cities not only change the direction of the winds, but, due to larger friction between air and such a 'relief', also its speed. A city lowersthe average annual speed of the wind by 25-50%. However, it increases the intensity. This is why the frequency of calm is here 15% greater on average, compared to that in the surrounding areas.The intensity of the wind is the pressure it has onto vertical surface. It is determined according to the Beaufort scale with 13 degrees established according tothe effect it has on different objects.  Beaufortnumber DescriptionWind speedLand conditions 0 Calm< 1 km/hCalm.

Debris and unsecured objects are hurled about.≥ 32.7 m/s The wind, just like any other climatic feature, changes throughout the day. Inland, the speed is the highest around midday, whereas it is the lowest at night. Incoastal regions the highest speed is at night as the difference between the temperature of the sea and land is the greatest then.The wind force has been used for long for windmills. Today, however, they look differently and are no longer used for grain grinding but for the production of power as this is one of the most important renewable sources of energy.CauseEffectIdentify 3 important supportingdetails that contribute to themain idea of the passage.1)2)3)Identify 2 details that are notvery important to the main ideaof the passage.1) 2)Write 1 brief paragraphsummarizing the main idea of the passage.

The first sentence is about Carol; Carol is the subject andthe verb is washed , the simple past tense.The second sentence is about the car, the car is thesubject and the verb phrase is was washed , the passive   Rule: The prefix re  adds again or back to the meaning of a word. This is one of the most common prefixes and can be correctly added to most verbs.voice in the past tense.What is the subject of the sentence(s) below?   Directions : Identify how the passives  is used in the sentence(s) below 1.
