i think so too

Answer 6

What is the difference in a light wave and a microwave?

They have different colors.
One is harmful and the other is not.
Their wavelengths are different.
Light is on the electromagnetic spectrum, but microwaves are not.

Answer 7

B

Answer 8

Subduction is when

two geologic plates are moving the same direction
one geologic plate is floating on top of another one
one geologic plate is pushed beneath another one
a mountain sinks into the ground

Answer 9

i think its C

Answer 10

In geology, subduction is the process that takes place at convergent boundaries by which one tectonic plate moves under another tectonic plate and sinks into the mantle as the plates converge. Regions where this process occurs are known as subduction zones.

Answer 11

correct

Answer 12

The three types of waves caused by earthquakes are

S, P, and L
S, P, and T
UV, S, and L
UV, IF, and S

Answer 13

i think s p t

Answer 14

me to

Answer 15

Science gives us

a way to investigate and learn
new opinions
all of these

Answer 16

i guess B

Answer 17

ok me also

Answer 18

The loudness of a sound wave is affected by the wave’s

pitch
frequency
amplitude
wavelength

Answer 19

Loudness depends on the amplitude of the sound wave. The larger the amplitude the more energy the sound wave contains therefore the louder the sound.

Answer 20

so C

Answer 21

yeah

Answer 22

how many questions are there left?

Answer 23

Answer 27

Which of the following is true about the asthenosphere?

It is a partially liquid layer of the inner Earth just below the lithosphere.
It is a completely solid layer of the inner Earth just below the lithosphere.
It is a completely solid layer of the inner Earth just above the lithosphere.
It is a partially liquid layer of the inner Earth that touches the inner core.

Answer 28

`The asthenosphere (from Greek ἀσθενής asthenḗs 'weak' + "sphere") is the highly viscous, mechanically weak[1] and ductilely deforming region of the upper mantle of the Earth. It lies below the lithosphere, at depths between approximately 80 and 200 km (50 and 120 miles) below the surface. The Lithosphere-Asthenosphere boundary is usually referred to as LAB. The asthenosphere is generally solid, although some of its regions could be melted (e.g. below mid-ocean ridge). The lower boundary of the asthenosphere is not well defined. The thickness of the asthenosphere depends mainly on the temperature. In some regions the asthenosphere could extend as deep as 700 km (430 mi). It is considered[by whom?] the source region of mid-ocean ridge basalt (MORB).[2`
