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>

Answer:
The two countries are in different hemispheres.
Explanation:
Australia is in the Southern Hemisphere and Bhutan is in the Northern Hemisphere.
Answer: Its presence is a good determinant of past hot climates. Its absence can also indicate cold climates.
Explanation:
18O and 16O are oxygen Isotopes, and are used in determining past climates. Heavier than the 16O with 10 neutrons and 8 protons, the 18O does not evaporate as easily and because of this, higher amounts are found in the tropics.
Together, they serve as good determinants of past climate by checking for their ratio in fossils.
Also the 18O isotopes are not present in polar regions as they precipitate before getting to higher altitudes. Cold areas, on the other hand, are high in 16O as they get trapped in glaciers. When climate changes in a location, the quantity of both of these oxygen isotopes also changes.
