valley
delta
hill
canyon
Answer:
its a delta
Explanation:
water moves threw the land pushing sediment, rocks and dirt close to the ocean making a river into several smaller one's.
Delta, landform develops when water causes deposition, bringing huge deposits of sediment to the mouth of a river. Therefore, the correct option is option B.
What is landform?A landform is essentially a natural geographic feature that can be seen on the earth's surface, such as hills, valleys, plateaus, and mountains. Not every landform is the same.
Some areas are much above sea level, while others are located very far below it. Both extremely soft and very hard materials are used to make different components of the product.
Some landforms are covered with flora, whereas others lack any kind of plant life. Some are really little, while others are enormous. Delta, landform develops when water causes deposition, bringing huge deposits of sediment to the mouth of a river.

I need help with this science!
Answer:
All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.
Answer:
Scientists classify living things at eight different levels: domain, kingdom, phylum, class, order, family, genus, and species. In order to do this, they look at characteristics, such as their appearance, reproduction, and movement, to name a few.

Light from the sun travels through space to Earth as transverse waves. These light waves DO NOT need a medium in which to travel. Think about the path that the light from the sun takes to shine through your Window.
How did that sunlight reach us all the way here on Earth? What does it travel through?
Light waves are transverse, like the waves in a water tank. The waves' resonant direction is at a 90° angle to the path of the light.
What is light?Electromagnetic energy that can be seen by the human eye is known as light or visible light. Between both the infrared and the ultraviolet, visible light is typically characterized as having wavelengths inside the range of 400–700 nanometers, or frequencies of 750–420 terahertz.
The term "light" in physics may be used to more generally describe electromagnetic radiation of just about any wavelength, whether or not it is visible. Waves are how light moves. These waves are transverse, like the waves in a water tank. The waves' resonant direction is at a 90° angle to the path of the light.
Therefore, light waves are transverse, like the waves in a water tank. The waves' resonant direction is at a 90° angle to the path of the light.

HURRY PLEASE In Maglev trains, fields exist between objects that are not in contact but can interact at a distance.
True
Or
False
In Maglev trains, magnetic force exist between objects that are not in contact but can interact at a distance.Hence, the statement is true.
What is a force?Force is defined as a cause which is capable of changing the motion of an object. It can cause an object which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as direction.Hence, it is a vector quantity.
It has SI units of Newton and is represented by'F'.Newton's second law states that force which acts on an object is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.
The concepts which related to force are thrust and torque .Thrust increases the velocity of an object and torque produces change in rotational speed of an object.

The given scenario is the best example of how the sun is the main source of energy for the water cycle.
What is water cycle?Water cycle is an atmospheric phenomenon in which the atmosphere and hydrosphere are involved. This process balance the amount of water in land and the atmosphere.
The heat energy radiated from sun make water sources warm up and water evaporates to the atmosphere. The water vapor in the atmosphere condenses to form liquid droplets and fall as rain.
Thus, solar energy is the main source to balance water content in atmosphere and land by water cycle and to maintain a living condition. Hence, option c is correct.
