Social Sciences

The prefix eco- means environment or habitat. It is often used in nonce compounds.

When water molecules evaporate, they gain energy from their surroundings to break free from the liquid state and enter the gaseous state. This absorption of energy from the environment causes a cooling effect in the surrounding area.

Environmental science is considered a multidisciplinary field that encompasses aspects of both natural and social sciences. While it is rooted in natural sciences like biology and chemistry, it also incorporates elements of social sciences such as sociology and economics in understanding human-environment interactions.

When a fluid is not moving, the force exerted on an object by the fluid is called buoyant force. Buoyant force is equal to the weight of the fluid displaced by the object. This force acts in the upward direction, opposing the force of gravity acting on the object.

Some fossils (mostly shells) have been known for thousands of years.

It is known that some of what we now call dinosaur bones were known in the middle ages, but the church called them fakes from the devil made to confuse people.

Paleontologists first began studying fossils in the 1800s.

The taxon Dinosauria was formally named in 1842 by paleontologist Sir Richard Owen, who used it to refer to the "distinct tribe or sub-order of Saurian Reptiles" that were then being recognized in England and around the world.

Madre de cacao leaves are effective in repelling mosquitoes because they contain natural compounds such as flavonoids and tannins that have insect-repellent properties. When crushed or dried, these compounds are released, creating a scent that mosquitoes find unpleasant and helps to drive them away.

A region is typically defined as an area with distinct physical, cultural, and political characteristics that distinguish it from other areas. Factors such as common language, climate, history, and traditions can create unique identities for different regions around the world. These characteristics help shape the identity and sense of belonging for the people residing in that particular region.

The two basic systems of forces are concurrent forces, where multiple forces act through a common point, and non-concurrent forces, where multiple forces do not intersect at a common point. Each system requires different methods for analysis and calculation.

B) Decreases. When detergent is added to water, it reduces the surface tension by disrupting the hydrogen bonding between water molecules. This causes the water molecules to spread out more evenly across the surface, lowering the surface tension.

When a sound wave is reflected, you may hear an echo or reverberation of the original sound. The reflected sound wave can create additional auditory cues that can affect how the sound is perceived in the environment.

Biological disasters belong to the class of natural disasters and define the devastating effects that may be caused by an enourmous spread of a certain kind of living organism - that may be the spread of a disease, a virus, an epidemics, but also just a sudden growth of the population of a certain kind of plants or animals, eg. a locust plague.

Examples of equilibrium include a book sitting on a table, a ball at rest on the ground, and a pencil standing vertically on its tip. In each case, the forces acting on the object are balanced, resulting in a stable state of rest.

If the useful energy output of a system is equal to the energy input, the following calculation can be done:

Efficiency = (Useful energy out) / (Energy In)
Efficiency = 1
Efficiency = 100%

Therefore, the machine you describe does have an efficiency value, which is equal to 100%. Very few situations like this exist though, unfortunately.

Tropical weather refers to the climate found in regions close to the equator, characterized by high temperatures, high humidity, and abundant rainfall. These areas typically experience warm weather year-round and are prone to the formation of tropical storms and hurricanes.

The unit that is equivalent to 1000 grams is called a kilogram.

Variables are the different thing in the experiment.

Ex.-Problem-Which ball rolls fastest?

Hypothesis-The Softball will roll fastest.

Investigation-Roll the balls at the same time and time them with a stopwatch.

Conclusion-Basketball rolled the fastest.

Variables-The balls.

Human geography is the study of people, where they lived, cultures, work, food, homes, and religion. Physical geography is the study of earth's land, features, landforms, mountains, valleys, plains, climate, environment, nonliving things, living things, plants, soil, and animals.

Yes it will float. The density of pure water will always be 1.00, anything under that such as 0.95 or 0.43 etc will float. Anything over 1.00 will sink for example 1.65 or 3.40 etc.

When scientists say there's a relationship between A and B they mean that they have reason to believe that A and B are parts of a system whose parts are causally related. This does not mean that A causes B or vice versa. It means that there might be many other parts of the system containing both A and B that somehow link A and B so that when A changes B does too, or vice versa. For instance, I believe that height is related to intelligence. I don't believe that height makes a person more intelligent or that intelligence makes a person taller. However, it's possible that better childhood diet would result in both greater intelligence and greater height. I would say that there's a relationship between adult height and adult intelligence.

the latitudes and longitudes are used to indicate the location and extension of a country or continent.longitudes influence the time of a place and divides the earth into various time zones whereas latitudes influence the duration of day and night and divide the earth into different time zones

Yes, light does produce heat. When light is absorbed by an object, the energy from the light is converted into heat, which can raise the temperature of the object. This is why objects can feel warm when exposed to sunlight or other sources of light.

When the brain stops functioning, vital bodily functions controlled by the brain cease, leading to irreversible damage. The brain requires a constant supply of oxygen and nutrients, which are delivered through blood flow controlled by the heart. Despite the heart continuing to beat, without brain function, the body cannot sustain life.

The Tropic of Capricorn passes through Botswana.

Geography is important to man because it helps us understand the world around us, including natural resources, weather patterns, and how human societies interact with their environment. It also provides insights into cultural differences, economic development, and political relationships between nations. Ultimately, geography plays a crucial role in shaping our understanding of the earth and our place within it.
