Where does 2 percent of all of the earths water exists in solid form?

2 percent of all Earth's water exists in the form of ice caps and glaciers, primarily located in Antarctica and Greenland.

What are some good science project questions?

  1. How does the type of soil affect plant growth?
  2. Does the angle of sunlight affect the rate of photosynthesis in plants?
  3. How does the pH level of water affect the growth of aquatic plants?
  4. What is the effect of different types of music on human heart rate?
  5. How does the temperature of water affect the rate of ice melting?

How many landmasses exist on earth?

0 my sweet heart. there is only flat land. that's because the world is flat

What effect does this organization does Sun Earth and Moon and on Earth's tides?

The gravitational pull of the Sun and Moon on Earth creates tidal forces, leading to the rising and falling of ocean water levels known as tides. The Sun and Moon's alignment determines the intensity and timing of tides, with the gravitational influence of the Moon being stronger due to its proximity to Earth.

How can you convert bar in to litter per second?

To convert bar (pressure unit) to liters per second (flow rate unit), you would need additional information such as the fluid being measured, temperature, and pipe diameter, as these factors affect the conversion. It is not a direct conversion and would require knowledge of fluid dynamics and engineering principles.

Why is force that are equal in size but opposite in direction balance force?

When two forces are equal in size but opposite in direction, they create a balanced force because they cancel each other out. This means that the forces do not result in any change in the object's motion, resulting in a state of equilibrium. As a result, the object will remain at rest or continue moving at a constant velocity.

What is geomophology?

Geomorphology is the study of the physical features of the Earth's surface, including their origin and evolution. It encompasses the processes that shape the landforms we see today, such as erosion, weathering, and tectonic activity. Geomorphologists often use a combination of field observations, laboratory experiments, and remote sensing techniques to understand these processes.

Why does oil transport over a large distance?

Oil is transported over long distances through pipelines, tankers, and trucks because it is a valuable commodity used for various purposes such as fuel production and manufacturing. These transportation methods are efficient and cost-effective for moving large quantities of oil from extraction sites to refineries and distribution centers around the world.

What accurately describes the main reaction that generates the Sun's light?

The main reaction that generates the Sun's light is nuclear fusion, specifically the fusion of hydrogen atoms into helium. This process releases a tremendous amount of energy in the form of light and heat, which is what sustains the Sun's brightness and warmth.

What is the name of the air that surrounds the earth?

The air that surrounds the Earth is called the atmosphere. It is composed of various gases such as nitrogen, oxygen, carbon dioxide, and others, and plays a crucial role in regulating the Earth's temperature and supporting life.

What are the relative sizes of each layer of the earth structure?

The Earth is divided into four main layers: the inner core, outer core, mantle, and crust. The inner core is the smallest layer, with a radius of about 1,220 km. The outer core is larger, extending from about 2,200 km to 3,000 km in depth. The mantle is the thickest layer, reaching depths of around 2,900 km to 2,900 km, and the crust is the thinnest layer, ranging from 5 km to 70 km thick.

What is mass mov wet?

Mass wasting is the downslope movement of rock, soil, and debris under the influence of gravity. Wet mass wasting refers to when water saturates the material, reducing friction and cohesion, making it more prone to sliding or flowing downhill. This can lead to events like mudslides, debris flows, and slumps.

What names do people call the earth?

Tellus

Terra

La Monde

Soil

Pachamama

Are some.

What are the elements and compounds found in the lithosphere called?

Elements and compounds found in the lithosphere are referred to as minerals. Minerals are naturally occurring inorganic substances with a specific chemical composition and crystal structure. They form the building blocks of rocks and are essential for various Earth processes.

Which statement correctly describes the density of Earth's mantle compared to the density of Earths core?

The density of Earth's mantle is lower than the density of Earth's core. The mantle is composed of solid rock while the core is made of mostly iron and nickel, which are denser materials. This difference in density contributes to the layering of the Earth's structure.

How does the temperature of the inner planets compare to the temperature of the outer planets?

The inner planets are typically warmer than the outer planets. This is because the inner planets are closer to the sun and receive more direct sunlight, leading to higher temperatures. In contrast, the outer planets are much farther from the sun and are colder as a result.

Which example shows how earth's surface has been changed by fast moving water?

The Grand Canyon is a prime example of how fast-moving water, in the form of the Colorado River, has carved out the deep canyons, steep cliffs, and intricate rock formations over millions of years. This dramatic landscape showcases the powerful force of water in shaping the earth's surface.

What does not usually trigger mass movement?

Events that do not typically trigger mass movements include minor policy changes, individual scandals, or isolated incidents that do not resonate with a large portion of the population. Movements usually require a broader issue or grievance that affects a significant portion of society to gain momentum.

What famous earthquake is convergent kind?

The 2011 earthquake in Japan, known as the Tōhoku earthquake, is a famous example of a convergent plate boundary earthquake. This megathrust earthquake occurred where the Pacific Plate subducted beneath the North American Plate, leading to significant devastation and triggering a powerful tsunami.

What are comprehensive notes?

Comprehensive notes are detailed and thorough records of information, typically gathered from lectures, textbooks, or other resources. These notes aim to capture key points, concepts, and details to aid in understanding and retention of the material being studied.

Why are earth rock layers different?

Rock layers are different and unique to each other due to the fact that each layer represents a time period. They are formed when rock, sediment, and minerals settle into one place for a long time and harden when another layer goes over it. Reading rock layers allow geologists to determine how much time has passed. They even sometimes tell of the history of the earth and all of the disasters that have occurred in each era.

What were the first land masses called?

The first land masses were called supercontinents, with the most recent one being Pangaea. These supercontinents formed and broke apart over millions of years due to the movement of tectonic plates on Earth's surface.

Which type of rock forms near the Earths surface without the influence of intense heat and pressure?

Sedimentary rock forms near the Earth's surface without the influence of intense heat and pressure. It is typically composed of fragments of pre-existing rocks or organic material that have been compacted and cemented together over time.

How thick is 25PT?

25pt is equivalent to 0.025 inches or 0.635 millimeters in thickness. This measurement is commonly used in the printing industry to specify the thickness of materials like paper or cardstock.

What major force shaps the landscape of the earth?

Tectonic plates shifting and colliding are a major force that shapes the Earth's landscape. Their movement causes earthquakes, volcanic activity, and the formation of mountain ranges and ocean trenches.
