Living Things
What is the process by which plants make their own food using sunlight, carbon dioxide, and water?
What is photosynthesis?
This natural satellite orbits the Earth and causes the tides.
What is the moon?
This state of matter has a definite shape and volume, and its particles are tightly packed together.
What is a solid?
This force pulls objects towards the center of the Earth.
What is gravity?
This term describes the variety of living things in an ecosystem.
What is biodiversity?
This tiny living thing, often a single cell, is the basic unit of life.
What is a cell?
This imaginary line runs from the North Pole to the South Pole and the Earth spins around it.
What is the axis?
This is the process of a liquid turning into a gas at the surface.
What is evaporation?
When an object's speed and direction change, this is the force that caused it.
What is a net force?
This gas, essential for photosynthesis, is absorbed by plants from the air.
What is carbon dioxide?
This is the process of animals changing their form and structure as they grow and develop.
What is metamorphosis?
This is a sudden shaking of the Earth's surface caused by the movement of rock beneath the surface.
What is an earthquake?
Energy that is stored in the nucleus of an atom is called this.
What is nuclear energy?
This term refers to an object's resistance to change in motion.
What is inertia?
This process helps reduce, reuse, and recycle materials to reduce waste.
What is sustainability?
These are the green structures inside plant cells where photosynthesis takes place.
What are chloroplasts?
This layer of the Earth is made up of tectonic plates that float on the semi-fluid asthenosphere.
What is the lithosphere?
This type of energy is created by the movement of electric charges.
What is electrical energy?
A force that acts against motion between two surfaces in contact is called this.
What is friction?
These are the natural habitats and communities of organisms.
What are ecosystems?
What term describes animals that eat both plants and other animals?
What are omnivores?
This term refers to the changing pattern of the moon's appearance as it orbits the Earth.
What are moon phases?
This type of simple machine consists of a sloping surface that reduces the amount of force needed to lift an object
What is an inclined plane?
This is the force that allows you to push or pull an object.
What is applied force?
This term describes the gradual change of one type of habitat into another over time.
What is succession?
