Waves are caused by blank and tides are caused by blank
Answers
Answer:
Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest. ... The gravitational pull of the sun and moon on the earth also causes waves.
Gravity is one major force that creates tides. In 1687, Sir Isaac Newton explained that ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth (Sumich, J.L., 1996). ... Tidal forces are based on the gravitational attractive force.
If the Tides is working then out “ High and low tides are caused by the Moon. The Moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the Moon and the side farthest from the Moon. These bulges of water are high tides“.

Analyze the given diagram of the carbon cycle below.
An image of carbon cycle is shown. The sun, a cloud, two trees, one towards left and the other towards right, an animal, lake, and a factory are included. Arrow A points from the sun to the left tree. Arrow B points from the air above the clouds to the left tree. Arrow C points from the factory towards the air above the clouds. Arrow D points from the air to the lake labeled Carbonates in Water. Arrow E points from the label Dead Organism under the animal to label Fossils and Fossil Fuels. Arrow F points from the right tree to the air.
Part 1: Which process does arrow F represent?
Part 2: Explain how matter is conserved during the process.
Part 3: Justify why this process is a recycling of carbon in the carbon cycle.
Use complete sentences to explain your answer. (10 points)
Answers
Answer:
Part 1:
Arrow F represents Cellular Respiration, showing how the tree produces carbon after it has finished the process of Cellular Respiration.
Part 2:
Matter is conserved in this image because it shows the process of Photosynthesis and cellular respiration. These are both examples of The Law of Conservation of Mass. During both of these processes, the mass of the reactants is the same as the mass of the products.
Part 3:
This process shows the carbon cycle by showing how carbon transfers to many different types of matter and back again. It shows the process of cellular respiration, which produces carbon using the products of photosynthesis, which uses the carbon produced by cellular respiration. This shows a cycle because each of them depends on the other.

Answers
Answer:

Wind resource produces the most energy for the smallest amount of resources. Hence option 5 is correct.
What are resources?Resources are defined as a type of physical substance, like land, air, or water, that people value and require. A resource can be classified as renewable or nonrenewable based on whether it can replace itself at the rate it is used up or whether it has a finite supply. When people cherish natural resources, they become resources themselves.
Renewable energy sources like sun and wind don't consume fuel and emit no greenhouse gases. They are much more efficient at converting energy into electricity, producing less waste and cost-saving results. With 83% of the world's electricity coming from renewable sources, hydroelectric energy is by far the most common.
Thus, wind resource produces the most energy for the smallest amount of resources. Hence option 5 is correct.
