The scientist credited with developing the theory of continental drift is Alfred Wegener. Wegener was a German geophysicist who first proposed the theory in 1912.
He hypothesized that the continents had once been joined together in a massive supercontinent called Pangaea and that they had subsequently drifted apart over time.
This theory was met with much resistance from the scientific community at the time, as there was little evidence to support it.
However, the discovery of plate tectonics in the 1960s provided evidence to support Wegener's theory and it is now widely accepted.
Wegener's theory of continental drift revolutionized the field of geology and provided a foundation for the study of plate tectonics.

Comets tend to be ________ than asteroids, and it is estimated that there are far ___________ large comets than large asteroids.
Comets tend to be faster than asteroids, and it is estimated that there are far more large comets than large asteroids.
There are reportedly far more massive comets than large asteroids, and comets are often faster than asteroids.
A comet would only need to be around 7 kilometers in diameter to contact Earth with enough energy to produce Chicxulub crater, but an asteroid would need to be a bigger 10 kilometers across because comets normally originate from farther off than asteroids do.
There are asteroids that are round, elongated, and even have satellites. A comet orbits the Sun similarly to an asteroid, however unlike an asteroid, it is made of ice and dust. Therefore, a comet's ice and dust content begin to evaporate as it approaches the Sun. Consequently, a comet appears blurry and/or has a tail when viewed through a telescope.
The coma of a comet can be up to 2 million miles across, despite the fact that the comet nucleus is typically less than 25 miles across. The asteroid Ceres is almost the same size as Texas. Vesta is an asteroid that is around the same size as Arizona.

Explain how a plant grows. What are phototropism, thigmotropism, and gravitropism?
Plants grow through a process called germination, where a seed absorbs water and begins to sprout. During the germination process, the seed's embryonic shoot (plumule) and embryonic root (radicle) emerge from the seed coat and start to grow.
What is phototropism, thigmotropism, and gravitropism?1. A plant's reaction to light for growth is called phototropism. Positive phototropism, which describes how plants grow toward the light, and negative phototropism, which describes how they grow away from the light. The hormone auxin, which causes cell elongation and growth on the plant's shaded side, is the cause of this reaction.
2. Thigmotropism is a plant's response to touch in terms of growth. Plants are able to sense physical contact and change the direction of their growth in response. This reaction is brought on by adjustments in the hormone balance of the plant, including a rise in the concentration of auxin in the cells that come into touch with the foreign substance.
3. A plant's response to gravity is known as gravitropism. Stems grow against gravity whereas roots develop in its favor (positive gravitropism) (negative gravitropism). This reaction is brought on by the statoliths, heavier organelles containing starch, which settle down and cause the opposite side of the plant's cells to develop.
Together, these processes help the plant grow in the healthiest way possible so that it can thrive and adapt to its surroundings.

What is it called when two plates slide past each other?
When two tectonic plates move horizontally relative to each other, it creates a boundary known as a transform boundary or transform fault. Transform boundaries occur where plates slide past each other in opposite directions, often at a jagged boundary.
These boundaries can result in earthquakes due to the buildup of stress and sudden release of energy as the plates move past each other. One of the most famous examples of a transform boundary is the San Andreas Fault in California, USA, where the Pacific Plate and North American Plate meet. The San Andreas Fault is responsible for many earthquakes in the region, and its presence highlights the important role that transform boundaries play in shaping the Earth's crust and the potential dangers they pose to human populations.

If a meteor with a 20 m in diameter impacts earth on land, approximately how big will the crater be?
The size of the crater created by a 20 m diameter meteor impacting the Earth will depend on several factors, including the velocity of the meteor, the angle of impact, and the type of material it strikes. On average, a 20 m diameter meteor is estimated to create a crater about 1.5 to 2 times its own diameter, so a crater of around 30 to 40 m in diameter can be expected. However, the actual size of the crater could be larger or smaller depending on the specific conditions of the impact.
What is a meteor?
A meteor is a small rock or piece of debris that travels through space and enters the Earth's atmosphere. When a meteor enters the Earth's atmosphere, it encounters friction and heat due to the atmospheric resistance, causing it to ignite and create a bright trail or shooting star in the sky. If a meteor reaches the surface of the Earth, it is called a meteorite. Most meteorites are relatively small, but some can be quite large and cause significant damage if they impact the Earth.

What do we call seismic waves that are transmitted along the outside of Earth?
Seismic waves that are transmitted along the outside of Earth are called Surface Waves.
What are the characteristics of Surface Waves?Surface waves are the slowest but most destructive type of seismic waves. They travel along the Earth's surface, causing the ground to move both vertically and horizontally. They have a lower frequency and higher amplitude than body waves, and they are responsible for most of the shaking experienced during an earthquake. Love waves move the ground in a horizontal, shearing motion, while Rayleigh waves produce both vertical and horizontal ground movement.
Surface waves are the slowest type of seismic waves, but they often cause the most damage during earthquakes because they move the ground vertically and horizontally, which can cause buildings and other structures to sway and shake. They travel through the Earth's crust and the uppermost part of the mantle.

as temperatures increase, which process is responsible for increasing the amount of water vapor in the atmosphere?
The conversion of liquid water into gaseous water is a process known as evaporation (water vapor). Water is moved from the Earth's surface to the atmosphere by evaporation.
More water vapor is taken into the air as a result of rising water vapor levels and warmer temperatures. As the temperature rises, more water is absorbed. Condensation, a process, transforms water vapor into liquid. It is the reverse of evaporation since it causes liquid water to become a vapor. Condensation occurs when the air either cools to its dew point or becomes too saturated with water vapor to contain any more water, depending on which scenario occurs first.. Plants may absorb the water and release it back into the atmosphere through transpiration and photosynthesis. The burning of plants in fossil fuels can also release water into the sky.

P wave is the first of the deflection waves on a typical ECG .The first abnormality is the P wave associated with right and left atrial depolarization.
In the heart, under normal conditions, the wave of depolarizing current originates in the SA node and reaches the ventricle via the myocardial conduction system. Anatomically, ventricular depolarization comes from apex to base and from endocardium to epicardium.
Depolarization occurs in the four chambers of the heart: first in both atria and then in both ventricles. The sinoatrial (SA) node in the wall of the right atrium begins depolarization in the right and left atrium, causing a contraction that corresponds to the P wave of the EKG.

how did scientists first figure out plates could sink into the interior of the planet, since no one can see this happening?
Scientists first figure out that plates could sink into the interior of the planet through plate tectonic theory. The plate tectonic theory is based on the phenomenon of constructive and destructive boundaries.
In a constrained region where two plates move past one another at a transform plate boundary, sheared-up mountain ridges and valleys develop. And where a plate passes over a hotspot, a mountain range of volcanoes develops; as the volcanoes are moved away from the hotspot by the plate, they age and get lower.
Some of the evidence of plate tectonic theory is mentioned here:
Because plate boundaries meet with the US Pacific coast, there are earthquakes, volcanic eruptions, and emerging mountain ranges there.Plate convergence causes large chunks of continental crust (India and Asia) to clash, creating the Himalayas, the tallest mountains on Earth.Pacific ring of fire and earthquakes are also the result of plate tectonics.Know more about Plate tectonic theory here
