Physical geography Answers

Hello,
My question is that if heating of the ground from the sun causes a low on the ground and a high pressure aloft at a higher elevation.
Then why doesn't it apply to a global level, where tropical high exist at both surface and higher elevations casing the same pattern of wind on both elevation even though both are more than 10km apart

How does fluvial discharge affect aggradation?

Using the topographic base map, zoom in so that Wauna Lake is centered in your window view. You can just see Bonneville Dam on the imagery overlay to the southwest of Wauna Lake. Wauna Lake is on the deposits of a landslide that occurred sometime between 1600 and 1760 and may be related to the 1700 Cascadia Earthquake. Look at the location of the landslide deposits on the Oregon side and the lobed nature of the deposits on the Washington State side of the Columbia River. Do you think this large, wet landslide originated in Oregon and stopped at the Columbia River or originated I Washington and crossed the Columbia River? Why?

Compare the current distribution of red spruce to its predicted distribution under a high (CO2) emissions scenario (recall: more emissions = warmer climate). How does the distribution differ between the two scenarios? HINT: use this website: https://www.fs.fed.us/nrs/atlas/tree/97
