History of Science

The first space mission to space was made by the USSR. The name of the mission was Vostok-1, on the craft Kedr (cedar in English), on April 12, 1961, piloted by Cosmonaut Yuri Gagarin.

If you are wondering about the first American mission to space, it was Mercury-3. The ship was called Freedom 7, it was launched on May 5, 1961, piloted by Alan B. Shepard Jr.

No, there are no continents on Mars. Mars does not have tectonic plates like Earth that lead to the formation of continents. Mars does have large landmasses such as the Tharsis volcanic plateau and the Hellas Planitia impact basin.

A concrete block is made from a mixture of water, cement, and aggregates such as sand or gravel. In this case, water acts as the solvent and cement serves as the solute which, when mixed together, forms a solid structure that hardens over time.

Yes, the South Pole is currently experiencing a small increase in ice due to the accumulation of snowfall. This growth, however, is relatively minor compared to the overall loss of ice occurring in Antarctica due to higher global temperatures causing ice melt.

The condensed electron configuration for Rhodium (Rh) is [Kr] 4d^8 5s^1.

To make a light bulb, a thin filament is suspended in a glass bulb filled with an inert gas. The bulb is then sealed, creating a vacuum or low-pressure environment to prevent the filament from oxidizing and burning out quickly. When electricity passes through the filament, it heats up and produces light.

P waves are longitudinal mechanical waves which are formed from alternating compressions and rarefactions. In a longitudinal wave the particle displacement is parallel to the direction of wave propagation.The particles do not move with the wave; they simply oscillate back and forth about their individual equilibrium positions. Thus particles in the ground move or vibrate along or parallel to the traveling direction of the P wave when it passes through them..

In the simplest terms, Oxygen is necessary for life because it is important in both photosynthesis and respiration, which require oxygen to occur.

In more complex terms, anaerobic organisms do not require molecular oxygen for metabolism. Oxygen is actually lethal to some of these anaerobes. In this case oxygen is still necesary as it forms OH groups used in enzymes and other molecules.

That's called the crust. The size of the crust compared to the size of the Earth's mantle can be compared to the size of the radius of an apple as the mantle and the apple's skin as the thickness of the crust. the crust is broken up into several plates that float and move around on the mantle's molten surface.

first I would like to tell you that the venation of apple leaf is like you that way.... dahil ito ya galing sa latin word na "derisdias pwende" na ang ibig sabin ay ikaw rin o ang iyong sarili na may buhay.

Thunderstorms can weaken as they move over land due to a loss of moisture and energy supply from the warm water. However, certain factors like terrain, atmospheric conditions, and local heating can sometimes help sustain or even intensify thunderstorms as they travel over land.

There is no layer of Earth that is predominantly molten rock. The only layer of Earth that is liquid is the outer core, however this is mainly iron and nickel.

The mantle, the thickest layer of the Earth, contains rock that is "ductile" (i.e. very viscous and able to flow very slowly), but not technically "liquid."

About ten years. The New Horizons space probe was launched towards Pluto in 2006 and is expected to get there in 2015. It experienced the fasted launch speed from earth ever, though is now still only about halfway to Pluto.

Mount Vesuvius is a stratovolcano characterized by a steep-sided cone shape and a crater at the summit. It is composed of alternating layers of lava, ash, and rock fragments. The volcano is known for its frequent eruptions, which can produce pyroclastic flows and ash clouds.

King Neptune's Ceremony, also called the Line-crossing Ceremony is a rite of passage for sailors crossing the Equator for the first time. Traditions vary between navies and over time. In some ceremonies, those who have already passed the Equator are called the Sons of Neptune and the ceremony takes place before King Neptune and his court.

I have been studying this topic at school and what i think that maybe not to many wildlife would live on the top of thsat mountin probably birds come and perch on the top at different times maybe also some plants

• stay indoors
• don't use the telephone
• unplug your tv
• don't take a shower or bath
• stay in your car if you're traveling
• don't stand near or under a tree

The discovery of oil in Texas in 1901 led to a boom in the oil industry in the United States. This created wealth for individuals and economic growth for the country. It also changed the geopolitical landscape as the U.S. became a major player in the global oil market.

Curium was obtained for the first time by Glenn Seaborg, Ralph James, Albert Ghiorso in 1944 at Berkeley Radiation Laboratories, USA.

Umm, plant or animal death, it has no special name.

In some cases, seeds may still be able to grow in polluted soil, but their growth may be stunted or the plant could be negatively affected by the pollutants present. Polluted soil can restrict nutrient availability, hamper root growth, and lead to plant diseases. It's generally not ideal for healthy plant growth.

The direction of the wind can vary depending on location, weather systems, and time of year. In general, the prevailing wind direction at a location is determined by factors such as the rotation of the Earth, pressure systems, and topography. For example, near the equator, winds tend to blow from east to west (easterly) as part of the trade winds, while in mid-latitudes, westerly winds are more common.

The African tectonic plate is approximately 61 million square kilometers in size. It covers most of the continent of Africa and includes portions of the Atlantic Ocean floor.

The movement you are referring to is called seafloor spreading. It occurs at mid-ocean ridges, where two tectonic plates move apart from each other, causing magma to rise and solidify, creating new oceanic crust.

Collenchymatous cells have rigid cell wall
