What scientific evidence supports the continental drift the theory?
Scientific evidence supporting the theory of continental drift includes the fit of the continents like puzzle pieces, matching geological features across continents, distribution of similar fossils and rocks across continents, and patterns of ancient climate change and glacial activity that align when continents are reconstructed into a single landmass. Additionally, modern techniques like GPS satellite monitoring continue to provide direct evidence of plate movements.
Where was the first stegosaurus fossil found?
The first Stegosaurus fossil was found in Morrison Formation rocks in Morrison, Colorado, in the United States in 1877 by paleontologist Othniel Charles Marsh.
What type of rocks are dolerite rocks?
Dolerite rocks are a type of igneous rocks (formed as a result of cooling of magma or lava). They are mafic (45-52% SiO2), and subvolcanic (formed within the earth's crust). Within this characterisation there is considerable variation. Please see the link.
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.
Why topographic maps are so important?
Topographic maps are important because they show detailed features of the Earth's surface, such as elevation, terrain, and natural landmarks. They are crucial for planning outdoor activities, understanding geology, managing land use, and navigating in remote areas. Topographic maps provide essential information for various fields, including environmental science, urban planning, and emergency management.
Why can't radiometric dating be used with accuracy on metamorphic rocks?
An accurate radiometric date can be obtained only if the mineral remained a closed system during the entire period since its formation this is why radiometric dating can't be used with accuracy.
Fibrinogen is a soluble plasma glycoprotein that plays a crucial role in blood clotting. It is converted to fibrin during the clotting process, helping to form a stable blood clot by interacting with platelets. Reduced levels of fibrinogen may lead to increased bleeding tendencies, while elevated levels can indicate inflammation or increased risk of blood clotting disorders.
How does science contribute to society?
Science contributes to society by improving our understanding of the world around us, leading to advancements in technology, healthcare, and agriculture. Scientific research helps to solve real-world problems, enhance quality of life, and drive economic development. Additionally, science education promotes critical thinking skills and fosters innovation in various industries.
What is stronger pavement concrite or asphalt?
In terms of compressive strength, concrete is generally stronger than asphalt. Concrete is more durable and has a longer lifespan compared to asphalt, but it is also more expensive to install. Asphalt is quicker to install, more flexible, and absorbs more noise. The choice between the two depends on factors like cost, climate, and expected traffic load.
What are landforms found in sharjah?
Some landforms found in Sharjah include desert dunes, salt flats, rocky outcrops, and wadis (dry riverbeds). The city also has a varied coastal landscape, with sandy beaches, mangrove forests, and coral reefs along the Arabian Gulf. Sharjah is known for its diverse natural features, offering a mix of desert and coastal environments.
When do plants get their food or do they?
Plants produce their own food through a process called photosynthesis. They use sunlight, water, and carbon dioxide to create glucose, which serves as their primary source of energy. This process occurs in the chloroplasts of plant cells.
That point is in northeastern China, about 70 miles west of the center of Beijing.
What includes water droplets and droplets from volcanoes?
Both water droplets and droplets from volcanoes are part of the water cycle. Water droplets form from condensation when water vapor in the air cools and changes phase. Droplets from volcanoes are created from the ejected molten rock, ash, and gases that cool and solidify in the atmosphere.
Which is easier to change the soil texture or structure?
It is generally easier to change the soil texture than the soil structure. Soil texture can be transformed through the addition of amendments like sand, silt, or clay. Soil structure, on the other hand, refers to how particles are arranged and bonded, making it more challenging to alter without time and proper soil management practices.
How meteorologists measure various weather patterns like tornadoes and hurricanes?
Hurricanes are measured through a combination of satellite imagery, manned flights into the storms, Doppler radar, and ground ad seas surface based observations.
Tornadoes are more difficult because they are smaller, shorter lived, and overall less predictable. Measurements have been made using Doppler radar and ground and ground based probes. Even then, most tornadoes do not have any measurements taken, so strength is estimated based on the damage caused.
Is there a difference in dirt and store bought soil?
Yes, there is a difference between dirt and store-bought soil. Dirt is the natural material found in the ground, while store-bought soil is a mix of organic matter, minerals, and other ingredients designed for specific gardening needs. Store-bought soil is often better suited for growing plants due to its nutrient content and consistency.
Geothermal energy comes from heat stored beneath Earth's surface, not from the sun. This energy is produced by harnessing heat from the Earth's interior, typically through the use of geothermal power plants that tap into underground reservoirs of hot water or steam. It is a renewable energy source that can be used to generate electricity and provide heating for homes and buildings.
How do hot spots and the plate tectonics theory account for the different ages of Hawaiian Islands?
it is because every island is formed at a different time when a volcano erupts so in theory if everything stayed the same except for the island in a million years or so the Hawaiian islands could in fact reach all the way to japan or south America
What is the difference between soil and volcanic soil?
Volcanic soil is formed from volcanic ash and lava, which are rich in minerals and nutrients. This makes volcanic soil fertile and ideal for agriculture. Regular soil, on the other hand, can vary greatly in composition and fertility depending on factors like weathering, organic matter content, and parent material.
What are some of the unusual properties of water?
Water has a high surface tension, allowing objects to float on its surface. It also has a higher boiling point and lower density in its solid state (ice) compared to its liquid state. Additionally, water exhibits capillary action, where it can move against gravity in narrow spaces.
Which biomes has the most varied seasons?
Temperate deciduous forests biomes have the most varied seasons. They experience four distinct seasons including winter, spring, summer, and autumn, with noticeable changes in temperature and vegetation throughout the year.
What is the habitat of any organism?
The habitat of an organism is the natural environment where it lives and thrives. It includes factors such as climate, resources, and other organisms present in that area that contribute to the organism's survival and reproduction. Each organism has specific habitat requirements that are essential for its existence.
What is the relationship between soil land and earth?
Soil is a part of the Earth's crust that forms the outermost layer of its surface. It is made up of minerals, organic matter, water, and air. Land refers to the solid part of the Earth's surface, which includes soil, rocks, and other materials. So, soil is a component of the land, which is a broader term encompassing various surface features of the Earth.
