Question

1. identify what does earths mantle consist of?
2. describe what is the inner core of earth like?
3. analyze how can changes on earth affect plant and animal life?

Explanation:

1. The Earth's mantle consists mainly of silicate rocks rich in magnesium and iron. It is semi - molten and can flow slowly over long periods.
2. The inner core of Earth is a solid sphere composed mainly of iron and nickel. It is under extremely high pressure and has a high temperature.
3. Changes on Earth such as climate change (temperature and precipitation changes), geological events (volcanic eruptions, earthquakes), and human - induced changes (habitat destruction) can affect plant and animal life. Climate change can alter the range and growth patterns of plants, and disrupt the migration and breeding patterns of animals. Geological events can cause immediate destruction of habitats. Human - induced changes like deforestation reduce available living space for plants and animals.

Answer:

1. Silicate rocks rich in magnesium and iron, semi - molten.
2. A solid sphere of iron and nickel, under high pressure and high temperature.
3. Climate change can alter plant and animal patterns, geological events can destroy habitats, human - induced changes reduce living space.
