What is the name of the idea that rock layers are all laid down parallel to the surface of the earth?
The idea that rock layers are typically deposited parallel to the Earth's surface is known as the Principle of Original Horizontality. This principle, proposed by geologist Nicholas Steno in the 17th century, suggests that sediments are originally deposited in horizontal layers due to the influence of gravity. When layers are found tilted or folded, it indicates that geological processes have occurred after their deposition.

How does air help shape the Earth?
the wind causes erosion, carrying the soil to any place on earth, dropping it onto any surface, thus controlling the earth's surface.
Why ozone doesn't settle to earth?
Ozone is a fairly unstable molecule. The ozone in the stratosphere will break down before it can diffuse to the surface.
What are the 5 chemical layers of the earth?
Physically, the Earth has numerous layers. Chemically, however, the solid portion of Earth can be divided into three distinct layers. In order from the surface going down, they are as follows: 1. The Crust--Major chemical constituents are oxygen, silicon, and aluminum. 2. The Mantle--Major chemical constituents are silicon, oxygen, iron, and magnesium. 3. The Core--Mostly iron and nickel.

Why does satellites orbit Earth at least 150 km above the surface?
The altitude of (manmade) satelites assures minimal signal interference when sending/recieving transmission. It also gives the device a "birds eye view", necessary for optimal data collection and transmission. note: a satelite can be defined as anything with an orbit around another mass.
If earth is hanging in space how do oceans not flow down?
Gravity holds the oceans (and us) to the Earth's surface, as the Earth orbits the Sun at nearly 30 kilometers per second (67,000 mph!). There is no up or down in open space and everything is in motion with regard to everything else. The Earth's rotation (1000 mph at the equator) causes the surface and oceans to bulge outward, but cannot overcome gravity. The concept that the earth is "hanging in space" is just a saying, like "the moon is hanging in the sky" or the like. The Earth has its planetary mass concentrated in the middle, and all things on its surface (and above it) are pulled "in" toward the center. We call the "inward" pull of the earth "down" instead. Water does, in fact, flow "down" on the surface, as objects are drawn toward the center of the Earth by gravity. The oceans are actually slightly "pulled away" from the Earth by the gravity of the Moon, which is the main basis for Earth's tides, the movement of water from one area to another. The Earth's spin affects tidal flow but does not create it.
Why does the earth have layers?
Looking at the whole earth is is layered with the densest materials in the core and the lightest materials forming the surface. This is because it was once molten and was therefore able to differentiate into density stratified layers. Looking in finer detail at the surface of the planet, the process of erosion and deposition of rocks causes sediments to be laid down in layers parallel to the surface of the planet. These then get deformed when the continents move and the layers can be seen in outcrop.
How do you know that the earth is in layers?
Scientists have determined the layers of the Earth by studying seismic waves from earthquakes. These waves travel through the Earth at different speeds and provide information about the density and composition of the different layers beneath the surface. By analyzing this data, scientists have been able to deduce the Earth's structure and layers.
True or false Motion parallel to earths surface is vertical motion Motion parallel to earths surface is vertical motion?
False. Consider a car moving on the road, along the earth's surface. That is considered to be Vx or Horizontal motion or velocity. If the car were to move perpendicular to the earth's surface that would be Vy or Vertical motion and velocity.
How do three processes act together to wear down and build up earth's surface?
Weathering breaks down rocks into smaller pieces, erosion transports these pieces to new locations, and deposition delivers these particles to build up new layers on the Earth's surface. Together, these processes continuously wear down and reshape the Earth's surface over time.
Is horizontal an adjective?
Yes. It is a form of the noun horizon. It refers to the dimension that is parallel to the Earth's surface (i.e. sideways) rather than vertical (up and down).
What is the process of breaking down rock and soil layers with water?
This process is called weathering. Water dissolves and erodes rock and soil layers through physical or chemical means. Over time, this can lead to the breaking down and reshaping of the Earth's surface.
How does pressure change as you go from the surface of the earth towards the center of the earth?
Pressure increases as you go towards the center of the Earth due to the weight of the Earth's layers above pushing down. At the Earth's core, pressure can reach extreme levels due to the immense mass of the overlying material.
In which temperature zone of Earth's atmosphere is the space dust first slowed enough by friction to be pulled to Earth's surface?
The space dust usually first enters Earth's atmosphere in the thermosphere, where the friction from the air slows it down. As it continues to descend, it passes through the mesosphere before reaching the lower layers where it can settle on the Earth's surface.
Lava cools down and accumulates into rock as it reaches Earth's surface?

What is the breaks down the Earth's surface?
Weathering!
What is the correct order of earth's atmospheric layers from earth's surface into outer space?
the layers of the atmosphere in order are troposphere, stratosphere, mesosphere, thermosphere, and exosphere
How do particles move in a surface wave?
Surface Waves can propagate only along the boundary of solid.Two types are:Rayliegh Waves propagate along boundary between two dissimilar solid media, in a plane perpendicular to the surface and containing the direction of propagation.Love Waves are polarized shear wave with an associated oscillatory particle motion parallel to the free space and perpendicular to the direction wave motion.
