Answer:
True
Explanation:
The vernal equinox are the two days in the year in which the sun is exactly above the Equator, one for each hemisphere.
In the Northern Hemisphere, it happens when the sun crosses the Equator going North, marking the beginning of the spring in this hemisphere. It happens in March. So this affirmative is True
Answer:
landward of oceanic trenches
Explanation:
Igneous activities leads to the production of magma.
An oceanic trench is one very distinguishing feature of the deep sea. It usually lies close to subduction zones where two plates pull together. In a subduction zone, the heavier lithospheric plate usually the oceanic plate sinks beneath the lighter continental plate. The convergence of the plate leads to series of earth tectonic activities that forms the trench.
Oceanic trenches are the deepest part of the earth and they indicate the point in the oceanic plate where subduction usually sets in. Landward of the trenches is the continental plate overriding the oceanic plate. As partial melting accompanies the subducting plate, magma forces its way up to form continental igneous activities. Therefore, we can observe volcanic arcs in these zones.
