years of research and development for maps to become accurate enough to fully rely on. Humans have invented many tools so that maps could be as accurate as possible. One of the most widely known tools would be the compass‚ satellite‚ longitude‚ latitude‚ etc. Although all these inventions have helped greatly in creating and developing maps‚ satellites have provided information that was incredibly accurate. Invention-the satellite The satellite is the most recent invention that humans made that

To what extent is the climate of the British Isles a product of the air masses that affect it? (40 marks) The British Isles are a group of islands located off the north-western coast of continental Europe. The climate is usually considered to be temperate maritime; however‚ the weather is very changeable from place to place and from time to time. Air masses greatly affect the weather experienced in the British Isles and therefore‚ its climate. An air mass is a body of air with uniform levels of temperature

because things are correlated or related does not mean one will cause the other to happen. An example of a positive correlation is age and income; people who are older tend to earn more money. An example of a negative correlation is latitude and temperature; as latitude increases‚ temperature tends to decrease. 4. Describe an experiment requiring the statistic ANOVA for analysis.

An atmosphere may be retained for a longer duration‚ if the gravity is high and the atmosphere’s temperature is low. Some planets consist mainly

Lakes are most abundant in high northern latitudes and in mountain regions‚ particularly those that were covered by glaciers in recent geologic times. The primary sources of lake water are melting ice and snow‚ springs‚ rivers‚ runoff from the land surface‚ and direct precipitation. In the upper part of lakes there is a good supply of light‚ heat‚ oxygen‚ and nutrients‚ well distributed by currents and turbulence. As a result‚ a large number of diverse aquatic organisms can be found there. The most

However‚ despite these improvements‚ agriculture is still highly dependent on climate since solar radiation‚ temperature‚ and precipitation are the main drivers of crop growth.

moisture differences between one place and another. These differences can occur due to the sun angle at any particular spot. The strong temperature contrast between polar and tropical air gives rise to the jet stream. Weather systems in the mid-latitudes‚ such as "extratropical cyclones"‚ are caused by instabilities of the jet stream flow. Because the Earth’s axis is tilted relative to its orbital plane‚ sunlight is pointed at different angles at different times of the year. On Earth’s surface‚
