What causes temperature to decrease?

Studies show that core body temperature decreases with age. Hypothyroidism, or an underactive thyroid, can also slow down metabolism, which can lead to a drop in body temperature. If your core body temperature dips down to 95 F (35 C) or lower, that’s considered hypothermia.

How does the temperature vary within a layer of the atmosphere give one example to support your answer?

More light is absorbed at higher altitudes compared to the lower stratosphere, so the temperature increases. But at 50 kilometers, the temperature levels out again in a region called the stratopause. … In the mesosphere, the temperature decreases with height again, because there is very little ozone to warm up the air.

What causes temperature variations in the four layers of the atmosphere?

Temperature differences in the four layers are caused by the way solar energy (energy from the Sun) is absorbed as it moves downward through the atmosphere. The Earth’s surface absorbs most of the Sun’s energy. Some of this energy is bounced back out by the Earth as heat, which warms the troposphere.

Why does the temperature of the atmosphere increase as it moves from the troposphere into and through the stratosphere?

Heat is produced in the process of the formation of Ozone and this heat is responsible for temperature increases from an average -60°F (-51°C) at tropopause to a maximum of about 5°F (-15°C) at the top of the stratosphere. This increase in temperature with height means warmer air is located above cooler air.

Why does temperature decrease with elevation?

The basic answer is that the farther away you get from the earth, the thinner the atmosphere gets. The total heat content of a system is directly related to the amount of matter present, so it is cooler at higher elevations.

Why does temperature decrease as altitude increases?

As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands), and the temperature decreases.

What is the coldest temperature in the stratosphere?

The temperature in the stratosphere ranges from negative 60 degrees Fahrenheit (negative 51 degrees Celsius) at the troposphere boundary to negative 5 degrees Fahrenheit (negative 15 degrees Celsius) at the top. The temperature increase is due to the ozone layer that absorbs ultraviolet light from solar radiation.
