Earth Sciences

The most meteoite material that people have dated stems from the time when the solar system formed and stems from bodies that never managed to grow the size of planets.

When people date materials that are that old, they use techniques that tell them when the material solidified for the last time either from a homogenous protoplanetary nebula or from a liquid magma.

Since the moon is believed to have formed by a giant impact of a roughly mars-sized body with the proto-Earth millions of years after most meteorites were formed and moon experienced ongoing magmatic activity thereafter, the ages obtained by radiometric dating of moon rocks are usually younger than those of meteorites.

The chunks of lithosphere that are scraped off of subducting plates and added to the edge of a continent are called accreted terranes!

Yes, Hawaii is an island. It is the largest of the 8 main Hawaiian islands, also known as the Big Island.

if youstanding one place and watch your shadow it will slowly get smaller/longer and move the reason is either that the sun is moving around and making the shadow different or the earth is moving around the Sun. This is why the sun appears to "rise and set". your body blocking the suns light is what makes the shadow

No, genes are not composed of hormones. Genes are segments of DNA that contain the instructions for producing proteins, while hormones are chemical messengers produced by various glands in the body that regulate different physiological processes. While genes can influence the production and regulation of certain hormones, they are not composed of hormones.

Metal-bearing rocks are called ore. They contain valuable metals that can be extracted and refined for various industrial purposes. Examples include iron ore, copper ore, and gold ore.

Silica gel is made from silicon dioxide, which can be derived from sources like quartz or sand. Sand is a common source for producing silica gel because it is abundant and easily accessible.

From the new moon (where it isn't visible) through to the full moon (when it is visible from earth as a full circle, all night long).

At "New Moon" the moon is between the earth and the sun, so we can only see the dark side (but because it's dark you can't actually see it !). Over the next 2 weeks the moon continues it's orbit around the earth, becoming progressively more and more visible as each day goes by, until we see the "full moon", which is when the moon is on the opposite side of the earth to the sun and is fully illuminated by the sun.

Over the following 2 weeks the visible area of the moon reduces, as the moon completes it's monthly orbit of the earth (actually 29.5 days). This is known as waning.

Kosovo. It was liberated from Serbia in 2008.

Yes, volcanoes can form far from plate boundaries in locations known as hotspots. Hotspots are areas of volcanic activity that occur deep within Earth's mantle, causing magma to rise and create volcanoes on the surface. Examples include the Hawaiian Islands and Yellowstone National Park.

It is believed that Kilauea grew above sea level some 50,000 years before present. However the information is just an estimate based on the eruptive history as well as the radiocarbon dating of certain surfaces of the volcano

Mesopotamians believed that ziggurats, large stepped pyramids, served as a link between heaven and earth. They were sacred structures where priests performed rituals and offerings to the gods in order to maintain harmony and balance between the two realms.

Scientists use properties such as luminosity, temperature, mass, size, and spectral characteristics to group stars. These properties help categorize stars into different classes based on their similarities and differences.

If you weighed 50 kg on Earth, you would weigh about 179 kg on Neptune. This is because Neptune's surface gravity is roughly 1.14 times that of Earth.

A fern fossil is an example of a preserved ancient plant specimen that provides valuable information about plant evolution, biodiversity, and environmental conditions in the past. By studying fern fossils, researchers can gain insights into the history of plant life on Earth and how plants have adapted to changing climates over millions of years.

No, the sun rises in the east in China, as it does in most locations on Earth. The direction of the sunrise and sunset is determined by Earth's rotation.

The approximate temperature of the sun's surface is around 5,500 degrees Celsius (9,932 degrees Fahrenheit).

Mount St. Helens erupted on May 18, 1980, in Washington state, USA. The eruption caused massive destruction, including the collapse of the north side of the volcano and the creation of a large crater.

Artificial satellites can be seen with the naked eye when they reflect sunlight. The best time to see them is typically during dusk or dawn when the sun is below the horizon but the satellite is still illuminated. Satellites appear as moving points of light against the night sky.

One is due to the spinning on axis, the entire Earth evenly get's lit.

Two is, due to the spinning on axis, no one place get's scorched nor frozen.

Three is, due to the spinning on axis, underground water is pressured to the surface.

Four is, due to the orbit, the seasonal changes allows plants and animals to go through birth, growth, and death.

The moon was not full on March 20 2012, it was a waning crescent

Day and night are created by the rotation of the Earth on its axis. As the Earth spins, different parts of the planet are exposed to the Sun's light, creating daytime in those regions and nighttime on the other side. This cycle repeats every 24 hours.
