Answer 1: The correct answer is the
crust and the upper mantle.
The lithosphere refers to a solid, rocky part of the Earth, that is the Earth's outermost layer. It is comprised of the crust and upper mantle (refer to attached image). The lithosphere is around 100 km deep.
Answer 2: The correct answer is its
crust.
The Earth's crust refers to the outermost rocky shell of the Earth where organisms live (refer to second image). The crust is made of solid rocks, including igneous, sedimentary and metamorphic rocks. The Earth's crust is around 30 km deep.
Answer 3: The correct answer is
iron and nickel.<span>
The Earth's core refers to the innermost or central part of the Earth. It lies around 2900 km beneath the Earth's surface and is spherical in shape. The Earth's core is comprised of an alloy (mixture) of the metals iron and zinc.It is made of two layers: the outer core and the inner core. </span></span>
Carbon is the basic building block of life . This is the reason carbon dating is effective, all living organisms contain carbon. Also, carbon is so important to life because virtually all molecules in the body contain carbon. ... For this reason it can form long chain molecules, each with different properties.

Answer:
The stream will flow fastest between 2 and 3.
Explanation:
On this map, we can see two basic elements, one being the contour lines, and the other being the color with which a stream is presented. The contour lines are giving us a good representation of the relief and where it is steeper and where it is less steep. Basically, where the contour lines are closer to each other, we have a steeper relief, and when the contour lines are further away, the relief is less steep.
The water moves under the influence of gravity, so downward. Where the steepness is the greatest, the gravity influences it the most, so it moves faster, while where the steepness is smaller, the gravity influences it less, so it moves slower. On this map, the contour lines are closest to each other between points 2 and 3, meaning it is the steepest part of the relief, and it is the place where the stream flows the fastest.
