Question		Answer
why does the world use time zones? start learning		The time zones were established in the 19th century in response to increased global communication and business. The system of time zones allows people to easily determine the time in another location.
what are features of the time zones in your city or country? start learning		The time zone where I live is one hour after Universal Time. When it's noon in my time zone, it's 11 am GMT in otherworlds.
solar noon start learning		a time each day when the sun is at the highest point in the sky
political boundary start learning		an imaginary line that separates one country or state from another.
confusion start learning		a skute of disorder in which something is unclear
frame of reference start learning		a set of criteria or stated values in relation to which measurements or judgements can be made .
GMT (Greenwich Mean Time) start learning		the time in the zero meridian that all other zones are based on.
time zone start learning		any are of 24 geographical regions used to determine time
international date line start learning		is an imaginary line halfway around the globe where the date jumps
daylight saving time start learning		is the practice of setting clocks one hour or more
universal time (UT) start learning		is the local time of the zero meridian which passes through Greenwich, England
Standard time start learning		is the official time of a zone or region
jogs start learning		is a jump of interruption in the straight line of a time zone
central meridians start learning		is a line that can be found at every 15th degrees of longitude, and is used to establish time zones.
What is the Earth system? start learning		The Earth system is the network of interconnected processes that occur on Earth.
What areas of study are included in geography? start learning		geology, biology, physical science, social science and political science
interconnected start learning		having all constituent parts linked or connected.
dependent start learning		requiring something else in order to function
natural resource start learning		a substance or process in nature that people use
worldwide start learning		applying to the entire Earth or many parts of it
limited start learning		not widely available
survive start learning		to remain alive
critical start learning		something that is necessary in order for something else to occur to be true
variable start learning		a factor that may change the quality, quantity, size, etc.
life-support system start learning		a set of conditions or factors that allow living things to survive in an environment
How do the biosphere and hydrosphere interact? start learning		The biosphere and the hydrosphere have two different definitions, but their domains overlap. The biosphere includes all life on Earth. This includes humans and other life on land. But it also includes aquatic life, which lives in the hydrosphere. However, some parts of the hydrosphere are not part of the biosphere. This includes water stored in the upper atmosphere.
lithosphere start learning		the layer that includes the rocky surface of the Earth
atmosphere start learning		the layer of air around the Earth
interact start learning		to behave in response to each other
physical start learning		related to qualities that are seen or touched
overlap start learning		to exist in an area that something else also exists in
hydrosphere start learning		the layer that includes all the Earth's water
crust start learning		the surface of the Earth, made up of rock and soil
troposphere start learning		the inner layer of the atmosphere, closer to the Earth than the stratosphere that contains most of the planet's air
biosphere start learning		set of all living organisms on the Earth
stratosphere start learning		is an outer layer of the atmosphere, farther from the Earth than the troposphere, that filters out harmful rays from the sun.
What are some features of the Earth's orbit around the sun? start learning		The Earth revolves around the sun, following an elliptical orbit. Since the path is not a perfect circle, the Earth's distance from the sun varies throughout the year. That is why a year is 365 days, with one extra full day every four years to account for the extra 0.25. However, these variations are too small to affect the seasons. The Earth makes one full revolution once every 365.25 days.
How do the Earth's movements affect conditions on the surface? start learning		The conditions on the surface of the Earth change depending on the position of the Earth in relation to the sun. As the Earth revolves, it remains at a fixed tilt. for half of the year and tilted away for the other half. This causes the changing seasons throughout the year. Of course, the conditions also change each day as the Earth rotates. The 24-hour rotation causes alternating days and nights. As a result, each pole is tilted towards the sun
alternate start learning		switch back and forth repeatedly
variations start learning		changes to the conditions
solar system start learning		network of objects that revolve around the sun.
elliptical start learning		rounded but not circular
orbits start learning		paths that planets follow around the sun
perihelion start learning		the orbital position of the Earth on January 3, when it is closed to the sun
aphelion start learning		the orbital position of the Earth on July 4, when it is farthest from the sun
resolve start learning		to move in circular motion around a central point
rotate start learning		to turn around a fixed point without changing location.
season start learning		part of the year during which a location has particular weather conditions
oblique ray start learning		light that is cast onto a point at a slant or incline
vertical ray start learning		light that is cast directly onto a point at a 90° angle
equinox start learning		an astronomical event in which the sun's rays are cast most directly on the equator
Tropic of Cancer start learning		an imaginary line that receives direct light during the Northern Hemisphere's summer solstice
Arctic Circle start learning		a region around the North Pole that receives a full day of daylight or darkness
Antarctic Circle start learning		a region around the South Pole that receives a full day of daylight or darkness
Tropic of Capricorn start learning		an imaginary line that receives direct light during the Southern Hemisphere's summer solstice
solstice start learning		an astronomical event in which a point on Earth is tilted farthest from or closest to the sun
daylight start learning		the presence of sunlight during the daytime, so that surroundings are easy to see
hemisphere start learning		is one half of the Earth, divided by a line such as the equator or a meridian
darkness start learning		a state without light, generally occuring at night
incline start learning		to learn or to deviate towards a particular direction, rather than being oriented straight up and down.
weather start learning		state of the atmosphere as it is experienced on the surface of the Earth in a particular time and place, and includes features like temperature and precipition
