Earth Sciences

it all depends where you are thinking. most are used to collect foods and fruits for the local people. i have been studying Costa Del Sol which has people using the trees to make their homes etc etc. but many people, transnational companies, have taken advantage of such rainforests and used them for commercial logging where the bulldozer will collect trees but also destroys them on its path. its things like this that can also lead to illegal logging, taking trees with no permission.

i know that people are worried about costa del sol because by 2020 the forest may be destroyed if not used sustainably.

the earth is made up of different plates and all the plates are different sizes, shapes and weight.

there are 2 types of plates, oceanic and continental.

a mountain is formed when 2 continental plates of the same weight collide into each other, it creates a mountain and the oceanic plates underneath them are pused down.

No, meteoric water refers to water that originates from atmospheric condensation and precipitation, rather than being carried by a meteor. Meteors typically burn up in the Earth's atmosphere and do not bring water to Earth.

Clover peas lupins.

Astatine (At) is the element in group 7 that is so rare that there are only a few grams of it on Earth. It is a radioactive element and is created through the decay of heavier elements.

As the altitude of the Sun increases, the Sun appears higher in the sky. This leads to increased intensity of sunlight, shorter shadows, and higher temperatures on the Earth's surface. It also indicates that it is closer to noon.

Tornadoes have the highest wind speeds, often surpassing 300 mph, and are relatively short-lived compared to other storms, typically lasting only a few minutes to a few hours.

If you have a single pulley, then you would need to exert 100N + an amount to overcome friction in your pulley.

If you have 2 pulleys, rope connected to a beam at top, descends through pulley on item lifted, and back up through pulley at the top and then down to where you are pulling. Then the force is split in half and you would exert 50N + an amount to overcome friction.

If you connect a rope to the item, up through a double pulley, down through a pulley on the item, and back up through the double pulley again and down to the person who is pulling. Then you divide the force into thirds, and the force is 33.3N + an amount to overcome friction.

Essentially count the upward pulling ropes and divide by that number. A rope simply looping over a pulley that you're hanging onto the other end of only counts as once, and would be no different from you pulling up directly on the object, or on a pulley connected to the object.

1. The tilt of Earth's axis causes different parts of the planet to receive varying amounts of sunlight at different times of the year.
2. As Earth orbits the sun, its axis maintains the same tilt relative to its path, leading to varying lengths of daylight throughout the year.
3. The shape of Earth's orbit around the sun is slightly elliptical, causing Earth to be closer to the sun in some parts of the year (resulting in summer) and farther away in others (resulting in winter).

Because the ingredients collect on the bottom when a product sits in one spot for a while. You shake to mix the ingredients back together so the product can be more effective.

For A+, it's Radiant Energy.

Haha, yes it is. A solution is a mixture that looks like it's made of one substance. Therefore, gingerale is a solution =) Hope that helps xD

Introducing a heat lamp at position B in the room would increase the temperature at that specific location, causing the isotherm values to shift towards higher values around that area. This would create a new thermal gradient in the room, with higher temperature values radiating outwards from the heat lamp.

The majority of energy on Earth comes from the sun. Solar energy is captured by plants through photosynthesis, which is then passed on through the food chain to other organisms. Additionally, the Earth's internal heat also contributes to energy sources such as geothermal energy.

when the river is carrying vast amounts of erdoded material as bedload. as water levels fall and the energy decreases the river drops its coursest material. the rapid deposition of its coursest material begins to block the main channel causing the river to divide into smaller channels that seek to find the way through the obsructing channel

The Earth's magnetic field is generated by the movement of molten iron in the outer core of the Earth. This movement creates electric currents which in turn produce a magnetic field around the planet.

Sea breezes occur during the day when cooler air from the sea moves towards the warmer land, while land breezes occur at night when the land cools faster than the sea, causing cooler air to move from the land towards the warmer sea. Sea breezes are typically stronger and happen during the day, whereas land breezes are weaker and occur at night. Both sea and land breezes help regulate temperatures in coastal areas.

Greek philosopher Pythagoras is credited with being one of the first people to suggest that the Earth is a sphere, around 500 BC. However, it was later Greek philosopher Aristotle who provided more evidence for this idea in the 4th century BC.

Algal blooms and red tides are both caused by the rapid growth of certain types of algae, often due to nutrient pollution in water. This overgrowth can lead to dense populations of algae, causing discoloration of the water and potential harm to aquatic life by depleting oxygen levels. Red tides specifically refer to algal blooms that produce toxins that can be harmful to marine organisms and humans.

Oxygen did not accumulate in the atmosphere until approximately 1.5 billion years after life appeared on Earth because early organisms did not produce oxygen as a byproduct of photosynthesis. It took a few billion years for oxygen-producing cyanobacteria to evolve and become abundant, resulting in the significant accumulation of oxygen in the atmosphere known as the Great Oxidation Event.

The free oxygen in Earth's atmosphere primarily comes from the process of photosynthesis carried out by plants, algae, and certain bacteria. During photosynthesis, these organisms use energy from sunlight to convert carbon dioxide and water into oxygen and glucose.Approximately half of Earth's oxygen is produced by marine plants, specifically phytoplankton.

The mineral with the highest density is often considered to be iridium, which has a density of around 22.56 grams per cubic centimeter. Iridium is a rare and expensive metal that is often found alloyed with other metals like platinum.

Pangaea was a supercontinent that existed about 335 million years ago. Over time, the landmass broke apart due to plate tectonics, eventually forming the continents we know today. This process is known as continental drift.
