Question

unit 1 review
identify the western and eastern hemispheres
identify the northern and southern hemispheres
what is the difference between weather and climate:
what are the 4 spheres:
the watery part of the earth
the upper most layer of the earth
the part of the earth where life lives
the layer of gas that surrounds the earth

Explanation:

The western hemisphere is the half of Earth which lies west of the prime - meridian and east of the 180th meridian. The eastern hemisphere is the half east of the prime - meridian and west of the 180th meridian. The northern hemisphere is the half of Earth north of the equator and the southern hemisphere is south of the equator. Weather is the short - term state of the atmosphere (e.g., temperature, precipitation, wind) at a specific place and time. Climate is the long - term average of weather conditions over a large area and a long period (usually 30 years or more). The four spheres of the Earth are the hydrosphere (watery part), lithosphere (uppermost layer), biosphere (where life lives), and atmosphere (layer of gas surrounding the Earth).

Answer:

• Western and Eastern Hemispheres: The western hemisphere is west of the prime - meridian and east of the 180th meridian; the eastern hemisphere is east of the prime - meridian and west of the 180th meridian.
• Northern and Southern Hemispheres: The northern hemisphere is north of the equator; the southern hemisphere is south of the equator.
• Difference between Weather and Climate: Weather is short - term atmospheric conditions; climate is long - term average of weather.
• Four spheres: Hydrosphere (watery part of the Earth), Lithosphere (uppermost layer of the Earth), Biosphere (part of the Earth where life lives), Atmosphere (layer of gas that surrounds the Earth)
