  • Weather hazards and climate change

    • Tectonic activity and plate boundaries - Edexcel

      Earthquakes and volcanic eruptions affect people all over the world. They are caused by the movement of tectonic plates. Tectonic hazards can destroy buildings, infrastructure and cause deaths.

    • Earthquakes and tsunamis - Edexcel

      Earthquakes are caused by the release of built-up pressure at plate boundaries. They can destroy buildings and infrastructure. Tsunamis can also occur, with equally devastating and deadly effects.

    • Volcanoes and volcanic eruptions - Edexcel

      Composite and shield volcanoes are found along plate boundaries. They have distinctive characteristics and can have both positive and negative effects on people and the landscape.

    • Tropical cyclones - Edexcel

      Tropical cyclones are immensely powerful and can travel up to speeds of 65 km/h. Resembling large whirlpools, they are made up of rotating, moist air, with wind speeds that can reach over 120 km/h.

    • Atmosphere and climate - Edexcel

      Heat from the equator is transferred around the globe in three cells that connect with each other, known as the tri-circular model. This creates a global pattern of atmospheric pressure and winds.

    • Climate change - Edexcel

      Evidence has shown that Earth鈥檚 temperature is rising due to an increase in greenhouse gases. This has created and will continue to create, a number of negative effects.
