Test: Our Environment - Class 7 MCQ

The physical environment includes things like land, water, and air around us. These are non-living parts of nature that make up Earth. They help us to have mountains, oceans, and the air we breathe. It's like the ground we walk on, the water we swim in, and the air we feel around us.

The lithosphere is like Earth's outer skin. It's tough and hard. We also call it the crust. It's the top layer of our planet where we find land, mountains, and soil. It's important for plants, animals, and us to live on.

• An ecosystem is like a community made by a group of living things in a specific place.
• Just like how you have your friends and family around you, different plants and animals live together in an ecosystem.
• They all help each other in different ways, like how we help our friends when they need us.
• It's important to keep this community balanced so that everyone can live happily and peacefully.

An ecosystem is like a community where different plants and animals live together in a particular place. It's like a big team where everyone helps each other to survive.

• Humans change their environment in dry areas by constructing wells, dams, and canals to access water.
• These structures help them to store and distribute water for drinking, farming, and other needs.
• It's like building special rivers to bring water to places where it's needed, making sure people and plants have enough to drink and grow.

The built environment consists of physical structures created by humans, such as houses, factories, and farms. Farms are places where food is grown, animals are raised, and crops are cultivated.

• It's important to protect the environment to keep the Earth clean and safe for all living things.
• When we take care of the environment, we help animals, plants, and people live healthy lives.
• Remember, by picking up trash, recycling, and using less plastic, we can all do our part to protect our planet for the future.

When we take care of nature by using things like trees, water, and air carefully, we are doing conservation. This helps us keep the Earth healthy and safe for animals and people.

The environment includes plants and animals. Plants provide us with oxygen to breathe, and animals are living creatures like birds, dogs, and cats. They all together make our environment beautiful and full of life!

Living organisms are animals, plants, and other living things. Human-made objects are things like buildings, roads, and vehicles that people create.

• The natural environment has two main types:
  • Landforms like mountains, valleys
  • Water bodies like oceans, rivers
• Landforms are the different shapes of the land.
• Water bodies are places where water is found, like seas and lakes.
• These parts of the natural environment are very important for all living things on Earth.

• The natural environment includes things like mountains, rivers, weather, and air. It can be split into two main types: the physical environment, which includes landforms, water bodies, climate, and air, and the biological environment, which includes living things like plants, animals, and tiny organisms.

• The physical environment includes things like land, water, and air - all the non-living elements around us. These things are essential for us to live and are part of the world we see every day. So, when we talk about the physical environment, we mean everything around us that is not alive, like the ground we walk on, the water we drink, and the air we breathe.

The Earth's rigid outer layer, also known as the crust, is where we live. It's like the Earth's skin, and it's made of rock. Mountains, plateaus, and plains are different kinds of landforms on this outer layer.

• An ecosystem is like a big community of living things, like plants and animals, all living together in one place and working with the environment around them. It's like a big team where everyone has a special job to do to keep things running smoothly. If one part of the team is missing or stops working, it can make things go wonky for everyone else in the ecosystem.

The built environment means structures made by people like houses, factories, and roads. When we talk about the built environment, we are focusing on things that humans have built to live and work in. So, it's like the homes we live in, the schools we study in, and the roads we travel on.

The human environment consists of the built environment created by humans like houses and the natural environment, including plants, animals, and landscapes. Natural elements are those not made by people, like forests, rivers, and mountains.

• It's important to protect our environment to keep the planet clean and safe for all living things.
• When we take care of our environment, we help animals, plants, and people live in a healthy and happy world.
• So, by picking up trash, recycling, and using resources wisely, we can all work together to make sure our planet stays beautiful and safe for everyone.

Sustainability means using resources carefully so that they can last a long time. It's like making sure we have enough of everything we need without causing harm to our planet.
