Answer:
B- Humidity
Explanation:
Humidity is a characteristic of the atmosphere!
Answer: 1. Created or nor destroyed. 2. converted from one form to another. 3. Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces. 4. kinetic. 6. Friction, Mechanical,Thermal. 7. One way to reduce friction is to use lubricants. Friction can also be reduced by switching from sliding kinetic friction to rolling kinetic friction. Another way to reduce friction is to make surfaces that rub against each other smoother. By polishing the surface, as polishing makes the surface smooth and friction can be reduced. Using lubricants such as oil or grease can reduce the friction between the surfaces. When objects are rolled over the surface, the friction between the rolled object and surface can be reduced by using ball bearings.
Explanation:
The correct option is (D) The ecological footprint of the United States is large because per capita resource use is high.
<h3>
What is ecological footprint?</h3>
- The Global Footprint Network advocates using the ecological footprint to determine how much nature is required to support a certain population or economy.
- The ecological footprint accounting system tracks how much nature is being used and produced.The Ecological Footprint calculates the total productive areas for which a population, a person, or a product competes on the demand side.
- It evaluates the ecological resources required by a specific population or product in order to produce the natural resources it consumes, as well as to absorb its waste, particularly carbon emissions.
- The biocapacity of a city, state, or country, on the supply side, measures how productive its ecological resources are (including cropland, grazing land, forest land, fishing grounds, and built-up land).
- These regions can also be used to absorb the garbage we produce, particularly our carbon emissions from burning fossil fuels, especially if they are left unharvested.

Answer:
Geological evidence indicates that dinosaurs became extinct at the boundary between the Cretaceous and Paleogene eras, about 66 million years ago, at a time when there was worldwide environmental change resulting from the impact of a large celestial object with the Earth and/or from vast volcanic eruptions.
The correct answer is - A. The Pacific Plate is moving in a northwest direction and creating subduction zones where it converges with other plates.
The Pacific Plate is an oceanic tectonic plate. It moves into northwestern direction. Since it borders with continental plates in the direction of its movement, that have bigger density in their crust, it is subducting bellow them. On the places of subduction, lots of heath, pressure, and magma are penetrating towards the surface, and that results in abundance of volcanic activity, and the creation of the so called ''Ring of Fire''.
