Because as they travel through the earth, the density of the material through which they are travelling will vary. This causes the speed of the wave to change which in turn results in a process known as refraction where the waves direction of propagation changes. As the density of the material in the earth continually increases with depth due to the increasing overburden pressure, the speed of the seismic waves will continuousy change with depth leading to continuous small changes in propogation direction which leads to the formation of a curved propagation path.
Geophysicists make use of this phenomenon to estimate the density and structure of the interior of the earth.

What evidence do we have to prove that their are layers inside the earth?
We know based on the timing and paths taken by seismic waves that such waves travel through different parts of the Earth at different speeds.
How does earths rotation affects the patterns of surface currents?
It causes the currents to move in curved paths instead of going in a straight line, which is known a the Coriolis effect.
Scientists have identified the boundaries between Earth's layers by studying?
The paths of seismic waves
What is the process by which small streams erode their forward paths through rock is called?
headward erosion
How do seismic waves help scientists understand earth's interior?
The speed of the waves that travel through the interior can tell the density of each layer of the Earth. Some waves can make it through certain layers, but not others.
Does a tornado travel straight?
Very often tornadoes, will travel in a straight line, but many do not, following meandering or curved paths instead.
What evidence do we have to prove that their are layers inside the earth?
We know based on the timing and paths taken by seismic waves that such waves travel through different parts of the Earth at different speeds.
Why do surface currents travel in curved paths around the earth?
Two main reasonsthe surface of the earth is not smooth so currents have to travel in curved paths to get around obstaclesCoriolis forces - because of the huge distances involved the differences of forces due to the changes in the circumference of the earth at different latitudes causes currents to curve even if they are trying to travel in a straight line. Note: it takes huge distances - on the order of miles - to see any effect from Coriolis forces (- despite the urban folklore out there about drains swirling different directions in the Northern and Southern hemispheres. Hint - they don't) Unless your sink or toilet is miles across, you won't be seeing Coriolis forces determining the direction of swirl as they drain.
What causes currents to move in curved paths instead of straight lines?
Earth's rotation causes the water to move in a curve; this is a manifestation of The Coriolis force.
How the earth rotation affects the pattern of surface currents?
It causes the currents to move in curved paths instead of going in a straight line, which is known a the Coriolis effect.
Why do s waves and p waves curved paths?
Because as they travel through the earth, the density of the material through which they are travelling will vary. This causes the speed of the wave to change which in turn results in a process known as refraction where the waves direction of propagation changes. As the density of the material in the earth continually increases with depth due to the increasing overburden pressure, the speed of the seismic waves will continuousy change with depth leading to continuous small changes in propogation direction which leads to the formation of a curved propagation path.

Why do p wave and s waves follow curved paths?
gravity
Why do wind currents move in curved paths?
Because of the Coriolis Effect
A mathematical procedure used in vector graphics to describe curved paths is called?
Bezier
What is a seisemic wave?
Geologists record the seisemic waves and study how they travel through Earth. different types of waves behave differently. The speed of the waves and the paths they take reveal the structure of the planet. That's all I know................................
Why are the paths of the surface planetary winds curved due to earths?
It is due to the earth's rotation. (source: January 2005 earth science regents exam)
Circular motion includes all curved paths not just movement in full circles?
Yes, circular motion refers to any motion along a curved path with a constant radius. This can include partial circles, ellipses, or any other curve with a consistent radius of curvature. It is a common type of motion in physics that involves a continuous change in direction.
