Question

focus skill: find main idea and details
answer the questions below to identify the main ideas a human geography.

1. how does the tilt of earth affect seasons in the northern and southern hemispheres?
2. what are the five layers of earths structure?
3. how is continental drift related to the movement of tectonic plates?
4. what are two of the ways tectonic plates move?
5. what are landforms and how do they change? what causes the changes?

Explanation:

1. The Earth's tilt causes different hemispheres to receive varying amounts of sunlight at different times of the year, leading to seasons. In summer, the hemisphere tilted towards the sun gets more direct sunlight and longer days, while in winter, the hemisphere tilted away has less direct sunlight and shorter days.
2. The five layers of Earth's structure are the crust, the uppermost solid layer; the mantle, which is semi - molten and flows slowly; the outer core, a liquid layer composed mainly of iron and nickel; the inner core, a solid sphere also of iron and nickel; and sometimes the lithosphere, which includes the crust and the uppermost part of the mantle.
3. Continental drift is the movement of the Earth's continents relative to each other. Tectonic plates are large slabs of the Earth's lithosphere. Continental drift occurs because the tectonic plates on which the continents sit are in constant motion due to convection currents in the mantle.
4. Tectonic plates move in three main ways: divergent (moving apart), convergent (moving together), and transform (sliding past each other). Two of these are divergent and convergent.
5. Landforms are natural features of the Earth's surface such as mountains, valleys, plains, etc. They change due to processes like erosion (by wind, water, ice), weathering (breaking down of rocks), and tectonic activity. Tectonic activity can create new landforms like mountains through plate collisions, while erosion and weathering gradually wear them down.

Answer:

1. The Earth's tilt causes different hemispheres to receive different amounts of sunlight, leading to seasons.
2. Crust, mantle, outer core, inner core, and sometimes lithosphere.
3. Continental drift occurs because tectonic plates on which continents sit are in motion.
4. Divergent, convergent.
5. Landforms are natural surface features. They change due to erosion, weathering, and tectonic activity.
