Question 22
Examine the uneven distribution of temperature over the earth’s surface.
Worked Solution & Example Answer:Examine the uneven distribution of temperature over the earth’s surface. - Leaving Cert Geography - Question 22 - 2021
Step 1
Identify the aspects of uneven temperature distribution
Answer
Temperature distribution across the Earth's surface is influenced by several factors, including latitude, altitude, ocean currents, and land use. These aspects can lead to significant variations in temperature in different regions.
Step 2
Discuss latitude and temperature distribution
Answer
Latitude is a crucial factor in temperature variation. The Earth is heated unevenly due to its spherical shape. Areas near the equator receive more direct sunlight throughout the year, resulting in higher temperatures. Conversely, polar regions receive less direct sunlight, leading to cooler temperatures.
Step 3
Discuss altitude's effect on temperature
Answer
Altitude also affects temperature distribution. As elevation increases, temperature typically decreases. This phenomenon is due to the thinning of the atmosphere at higher altitudes, which holds less heat. Mountainous regions, therefore, tend to experience lower temperatures compared to surrounding lowland areas.
