📖 Unit 10: Planet Earth - Reading lớp 9

Both of my parents love travelling, and they usually take us along. My mum told me that I started travelling with them when I was just four months old. It was a short trip to a city 120 kilometres away from our home town. Mum said I was a good girl since ate and slept during the trip without ever crying.

Every year my family goes on different trips from 2 days to 2 weeks. We normally don't stay in resorts. Instead we stay at homestays where we can get to know more about the life and culture of the people in those areas. We eat with them, watch them cook, and go hiking with them.

Sometimes we go abroad for our holidays. I still remember when I went to Disneyland in Hong Kong and later visited the Taronga Zoo in Sydney. I will never forget the moment seagulls took some snacks from my hands when we were sitting outside the Sydney Opera House.

I believe that when we travel together, we can strengthen our bonds and have great memories with our beloved family members.

Landforms The surface of Earth has different landforms, which differ in size and shape. They can be mountains, valleys, deserts, dunes, or plateaus. Mountains are formed as a result of earthquakes, volcanic eruptions, and tectonic movements. Valleys can be V-shaped or U-shaped, are low-lying areas between mountains and hills. Deserts are dry areas which have very little rainfall and the daytime temperature is very high.

Dunes are small hills made up of sand. They are created from the flow of the water. Plateaus are flat areas and highlands, which are separated from their surroundings.

Glaciers are the frozen bodies of water, which cover almost 10% of Earth's land area, and are sources of fresh water on Earth. Bodies of water on Earth also provide sources of water, food, medicines, and energy to humans. They help maintain biodiversity and play an important role in transportation.
