Answer:
The amount of sunlight changes when moving between north and south.
Explanation:
Climate change results from global warming which is an increase in the temperature of the earth.
The sun is the primary source of temperature change on earth, and latitude place a great role in the amount of sunshine that come to an area. Places at high latitude receive less sunlight when compared to places at low latitude, this in turn determines how warm or cold a region can be. On the other when moving from east to west, it is along longitudinal lines and this can be on same elevation, thus there are no significant changes in temperature.
Therefore sunlight plays a key role in altering the temperature along latitudes.
Answer:
A, B and D
Explanation:
The continental crust contains igneous, sedimentary and metamorphic rocks. Along convergent plate boundaries, the continental crust gets renewed with igneous rock providing more rock to be made into sedimentary rock. The sedimentary rock can then continue to sink into the crust becoming metamorphic. Due to this variety of types of rock, the minerals can be diverse, including sodium, potassium, aluminium and calcium. Continental crust is also much thicker, up to 70km.
Answer:
Sample Response: Spring tides occur when the moon is full or new. Earth, the moon, and the Sun are in a line. The moon’s gravity and the Sun’s gravity pull Earth’s crust and ocean water. This causes tides to be higher than normal.
At neap tide, the moon and the Sun are at right angles to each other. This happens during the first and third quarters of the lunar cycle. At neap tide, the Sun’s gravity and the moon’s gravity are balanced. High tides are lower; low tides are higher.
