1. explain the greenhouse effect in the earths atmosphere and explain what is happening today in the world to change this. (3 marks)

draw a diagram of the greenhouse effect within the earths atmosphere. (4 marks)

Explanation:

The greenhouse effect occurs when certain gases in Earth's atmosphere (greenhouse gases like carbon - dioxide, methane) trap heat from the sun. This is a natural process that warms the planet. Today, human activities such as burning fossil fuels (coal, oil, gas), deforestation, and industrial processes are increasing the concentration of greenhouse gases, enhancing the greenhouse effect and leading to global warming. To change this, efforts are being made to reduce emissions through renewable energy adoption (solar, wind, hydro), improving energy efficiency, and reforestation.
As for drawing the diagram, the key elements include the sun emitting solar radiation, some of which is absorbed by the Earth's surface and re - emitted as infrared radiation. Greenhouse gases in the atmosphere absorb and re - radiate this infrared radiation back towards the Earth's surface, warming it.

of greenhouse effect: Natural process where greenhouse gases trap heat. Human activities are enhancing it. Solutions include renewable energy, energy efficiency, and reforestation.
For the diagram, include sun, Earth's surface, infrared radiation, greenhouse gases, and the flow of radiation being trapped.
