Question 11 (3 points)
what have scientists learned from studying seismic waves that travel through earth's
interior
there is almost no layering between earth's surface and its core.
the outer core of the earth is liquid.
seafloor spreading is the result of earthquakes that can occur at quite a
distance,
the mantle of the earth is a place where molten rocks remain in rigid alignment
with one another

The outer core of the earth is liquid.  

Explanation:

Seismic waves travel through the Earth at different speeds and are reflected and refracted diffracted differently as they encounter layers of different densities.

By analyzing these waves, they have concluded that there is an inner core of solid iron surrounded by a liquid outer core consisting of nickel and iron.

A is wrong. The Earth consists of several layers

C is wrong. Seafloor spreading is caused by the movement of tectonic plates away from each other.

D is wrong. The mantle is mostly solid rock.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
