In summary, if the Earth was composed entirely of water and received 1.27X10^17W of radiant energy from the Sun, it would take approximately 5.7x10^5 years for the Earth to reach 90 degrees Celcius at 40 degrees Celcius. This is assuming that none of the energy is radiated or reflected back into space and the specific heat of water is 4.186J/g c.

1. The Earth intercepts 1.27X10^17W of radiant energy from the Sun. Suppose the Earth, of volume 1.08X10^27 m^3, was composed of water. How long would it take for the Earth at 40 celciues to reach 90 celcius , if none of the energy was radiated or reflected back out into space?
The specific heat of water is 4.186J/g c

a-5.7x10^5 y
b-5.26x10^4 y
c-110.8 y
d-5.04x10^7 y
e-56 y


This is the same one with one different number from 40c instead of 20c i calculated and still wrong i guess its a?

Any idea?
 

1. Why is the temperature of the earth increasing?

The temperature of the earth is increasing due to the increase in atmospheric concentrations of greenhouse gases, such as carbon dioxide, methane, and nitrous oxide. These gases trap heat in the atmosphere, causing the overall temperature to rise.

2. How do scientists measure the temperature of the earth?

Scientists measure the temperature of the earth using a variety of methods, including satellite measurements, ground-based weather stations, and ocean buoys. These measurements are then combined to create a global temperature record.

3. What is the impact of rising temperatures on the earth?

Rising temperatures can have a range of impacts on the earth, including melting glaciers and sea ice, rising sea levels, more frequent and severe weather events, changes in plant and animal habitats, and disruptions to global food supplies.

4. Can human activities affect the temperature of the earth?

Yes, human activities, particularly the burning of fossil fuels and deforestation, are major contributors to the increase in greenhouse gases and subsequent rise in temperature. Other human activities, such as agriculture and land use changes, also play a role in altering the earth's temperature.

5. What can be done to address the issue of rising temperatures?

To address rising temperatures, it is crucial to reduce greenhouse gas emissions and transition to renewable energy sources. Additionally, implementing sustainable land management practices and conserving natural habitats can also help mitigate the effects of rising temperatures.
