1st Grade Science Quiz On Natural Resources And Man-made Resources!

Explanation
Natural resources are things that are found in nature and are not created by humans. They include materials such as air, water, minerals, plants, and animals, which are essential for the survival and well-being of living organisms. Man-made resources, on the other hand, are created by humans and do not occur naturally. Therefore, the correct answer is natural resources.

Explanation
Water, soil, and coal are examples of natural resources because they are all found in nature and are used by humans for various purposes. Water is essential for all living organisms and is used for drinking, agriculture, and industrial processes. Soil is necessary for growing crops and is also used for construction purposes. Coal is a fossil fuel that is used for generating electricity and as a fuel source in industries. These resources are limited in quantity and need to be managed sustainably to ensure their availability for future generations.

Explanation
Natural resources are the materials or substances that are found in nature and are essential for human survival and development. These resources include air, water, land, minerals, forests, and wildlife. They are not created by humans and are available in their natural form. Natural resources are crucial for various human activities such as agriculture, industry, and energy production. They provide raw materials for manufacturing and are also important for maintaining ecological balance. Therefore, natural resources are the correct answer as they are directly obtained from nature.

Explanation
A road accident can be considered as a natural disaster because it is an event that occurs naturally without human intervention and causes significant damage and loss of life. While road accidents are often caused by human error or negligence, they can also be triggered by natural factors such as weather conditions or wildlife crossing the road. Additionally, road accidents can have widespread effects on communities and infrastructure, similar to other natural disasters like earthquakes or stampedes.

Explanation
We use rocks for the purpose of building. Rocks are a natural resource that can be used in construction for various purposes such as creating foundations, walls, and pathways. They provide stability and durability to structures and are commonly used in the construction industry. Additionally, rocks can be used as decorative elements in landscaping projects.

Explanation
A resource that is derived from nature is called a natural resource. This term refers to any material or substance that occurs naturally in the environment and is used by humans for various purposes. Examples of natural resources include water, air, minerals, forests, and wildlife. These resources are essential for the survival and well-being of both humans and other living organisms. They can be renewable, such as solar energy or wind power, or non-renewable, such as fossil fuels like coal and oil. Natural resources play a crucial role in sustaining life on Earth and are vital for economic development and human progress.

Explanation
We inhale oxygen because it is essential for our body's respiration process. Oxygen is needed for the cells in our body to produce energy through a process called cellular respiration. When we breathe in, oxygen enters our lungs and is then transported to the bloodstream, where it is carried to all the cells in our body. These cells use oxygen to break down glucose and produce ATP, which is the energy currency of our body. Without oxygen, our cells would not be able to generate enough energy to function properly.

Explanation
Trees undergo a process called photosynthesis, where they absorb carbon dioxide from the atmosphere and release oxygen as a byproduct. This oxygen is then released into the air through tiny pores called stomata on the surface of leaves. Therefore, the correct answer is oxygen.

Explanation
Water - 70% of the Earth is covered in water.

Explanation
Approximately 70 percent of Earth's surface is covered by water. This includes the oceans, seas, lakes, rivers, and other bodies of water. This large percentage of water coverage is a significant feature of our planet and plays a crucial role in various ecological processes and the overall balance of the Earth's climate.
