Answers
Answer:
a. A globe is a spherical figure which is a miniature form of earth.
b.A map is a symbolic representation of selected characteristics of a place, usually drawn on a flat surface. Maps present information about the world in a simple, visual way.
c.Latitude is an angle (defined below) which ranges from 0° at the Equator to 90° (North or South) at the poles.
d.Longitude is the measurement east or west of the prime meridian.
e.Climate means the usual condition of the temperature, humidity, atmospheric pressure, wind, rainfall, and other meteorological elements .
f.Air pollution is a type of environmental pollution that affects the air and is usually caused by smoke or other harmful gases, mainly oxides of carbon, sulphur and nitrogen.
g.Noise pollution is generally defined as regular exposure to elevated sound levels that may lead to adverse effects in humans or other living organisms.
Answer:
Heya m8! this is your answer.
Explanation:
i) Globe : globe is a spherical model of Earth, of some other celestial body, or of the celestial sphere. Globes serve purposes similar to maps, but unlike maps, they do not distort the surface that they portray except to scale it down. A model globe of Earth is called a terrestrial globe.
ii) Map: map is an image of an area, usually of the Earth or part of the Earth. A map is different from an aerial photograph because it includes interpretation. Many maps are called "charts" such as star charts and nautical charts. Before the late 20th century almost all maps were on paper. Today, many maps are digital, and can be seen on smartphones and computers. However, paper maps are still used.
iii) Latitude : Latitude is an angle (defined below) which ranges from 0° at the Equator to 90° (North or South) at the poles. Lines of constant latitude, or parallels, run east–west as circles parallel to the equator. Latitude is used together with longitude to specify the precise location of features on the surface of the Earth.
iv) Longitude: Longitude is the measurement east or west of the prime meridian. Longitude is measured by imaginary lines that run around the Earth vertically (up and down) and meet at the North and South Poles. These lines are known as meridians. ... Degrees of longitude are divided into 60 minutes.
v) Revolution: The movement of the Earth around the Sun in a fixed path is called a revolution. The Earth revolves from west to east i.e, in the anticlockwise direction. The Earth completes one revolution around the Sun in one year or precisely in 365.242 days. The revolution speed of the earth is 30 km/s-1.
vi) Climate: Climate means the usual condition of the temperature, humidity, atmospheric pressure, wind, rainfall, and other Meteorology|meteorological Weather|elements in an area of the Earth's surface for a long time. In simple terms climate is the average condition for about thirty years. Climate and weather are different.
vii) Air Pollution: Air pollution refers to any physical, chemical or biological change in the air. It is the contamination of air by harmful gases, dust and smoke which affects plants, animals and humans drastically. ... An increase or decrease in the composition of these gases is harmful to survival.
viii) Noise Pollution: Noise pollution, also known as environmental noise or sound pollution, is the propagation of noise with ranging impacts on the activity of human or animal life, most of them harmful to a degree. ... High noise levels can contribute to cardiovascular effects in humans and an increased incidence of coronary artery disease.
